Objective: To evaluate the prevalence and characteristics of recreational cannabis use in women with pelvic pain, and to examine the influence of cannabis legalization on these parameters., Methods: We conducted a retrospective analysis of a prospective registry of women with self-reported moderate-to-severe pelvic pain referred to a tertiary care clinic in Vancouver, Canada, 2013-2019. We excluded patients aged 18 years or younger and those with unknown data on cannabis use. Demographic, clinical, and validated questionnaire data were extracted for two main analyses: 1) comparison of current cannabis users with current nonusers, and 2) comparison of current cannabis users who entered the registry before cannabis legalization (October 17, 2018) with those who entered the registry on or after legalization., Results: Overall, 14.9% (509/3,426) of patients were classified as current cannabis users. Compared with nonusers, cannabis users were younger (P<.001), had lower levels of education (P<.001) and lower household income (P<.001), were taking opioids (P<.001), antiinflammatories (P=.003), neuromodulators (P=.020), and herbal medications (P<.001) more frequently. They had worse questionnaire scores for depression, anxiety, pain catastrophizing, quality of life, and pelvic pain severity (P<.001 for all). After cannabis legalization, prevalence of current cannabis use increased from 13.3% (366/2,760) to 21.5% (143/666) (P<.001). Compared with prelegalization, postlegalization users were associated with higher levels of education (P<.001), worse anxiety (P=.036), and worse pain catastrophizing (P<.001) scores. They were taking fewer antiinflammatories (P<.001), neuroleptics (P=.027) and daily opioids or narcotics (P=.026), but more herbal medications (P=.010)., Conclusion: Recreational cannabis use increased among patients with pelvic pain after legalization in Canada. Cannabis users had worse pain-related morbidities. Postlegalization, cannabis users were less likely to require daily opioids compared with cannabis users before legalization. The role, perceived benefits, and possible risks of cannabis for pelvic pain require further investigation., Clinical Trial Registration: ClinicalTrials.gov, NCT02911090., Competing Interests: Financial Disclosure Alasdair M.

Chronic pelvic pain affects one in seven women worldwide, and there is an urgent need to reduce its associated significant costs and to improve women's health. There are many correlated factors associated with chronic pelvic pain (CPP), and analyzing them simultaneously can be complex and involves many challenges. A newly developed interaction ensemble, referred to as INTENSE, was implemented to investigate this research gap. When applied, INTENSE aggregates three machine learning (ML) methods, which are unsupervised, as follows: interaction principal component analysis (IPCA), hierarchical cluster analysis (HCA), and centroid-based clustering (CBC). For our proposed research, we used INTENSE to uncover novel knowledge, which revealed new interactions in a sample of 656 patients among 25 factors: age, parity, ethnicity, body mass index, endometriosis, irritable bowel syndrome, painful bladder syndrome, pelvic floor tenderness, abdominal wall pain, depression score, anxiety score, Pain Catastrophizing Scale, family history of chronic pain, new or re-referral, age when first experienced pain, pain duration, surgery helpful for pain, infertility, smoking, alcohol use, trauma, dysmenorrhea, deep dyspareunia, CPP, and the Endometriosis Health Profile for functional quality of life. INTENSE indicates that CPP and the Endometriosis Health Profile are correlated with depression score, anxiety score, and the Pain Catastrophizing Scale. Other insights derived from these ML methods include the finding that higher body mass index was clustered with smoking and a history of life trauma. As well, sexual pain (deep dyspareunia) was found to be associated with musculoskeletal pain contributors (abdominal wall pain and pelvic floor tenderness). Therefore, INTENSE provided expert-like reasoning without training any model or prior knowledge of CPP. ML has the potential to identify novel relationships in the etiology of CPP, and thus can drive innovative future research., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2020 Elgendi, Allaire, Williams, Bedaiwy and Yong.)

Objective: To investigate the role(s) of hyaluronan synthase 2 (HAS2) and hyaluronan in disease progression of endometriosis and epidermal growth factor (EGF)-induced motility changes of endometriotic cells., Design: A case-control experimental study and in vitro primary cell culture study., Setting: University hospital-affiliated research centers., Patients: A total of 21 women with stage I/II endometriosis, 33 women with stage III/IV endometriosis with endometrioma, and 32 women without endometriosis were included in our study., Interventions: Serum, eutopic endometrial tissues, and/or ectopic endometriotic tissues were collected. Primary eutopic endometrial stromal cells (EuESCs) and ectopic ovarian endometriotic stromal cells (OvESCs) were isolated and cultured from women with ovarian endometrioma, and then treated with or without EGF., Main Outcome Measures: The concentrations of EGF and hyaluronan in serum were analyzed by enzyme-linked immunosorbent assay. The expressions and localizations of EGF receptor (EGFR), phosphorylated-(p)EGFR, HAS2, and hyaluronan receptor CD44 in tissues were examined by immunohistochemistry. The mRNA and protein levels of HAS2 in EuESCs and OvESCs were examined by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blot, respectively, and the concentrations of hyaluronan in conditioned medium were examined by enzyme-linked immunosorbent assay (ELISA). Cell motility was evaluated by transwell migration/invasion assays., Results: Serum EGF and hyaluronan concentrations were higher in women with stage III/IV endometriosis than in women with stage I/II or without endometriosis. EGFR, pEGFR, HAS2, and CD44 were immunolocalized in eutopic endometrium and ectopic endometriotic lesions, and the expressions of pEGFR and HAS2 were elevated in ectopic endometriotic lesions compared to eutopic endometrium. Treatment with EGF upregulated HAS2 and hyaluronan expression as well as cell migration and invasion in both EuESCs and OvESCs, and pharmaceutical blocking of EGFR abolished these effects. In addition, knockdown of HAS2 by small interfering RNA attenuated both basal and EGF-induced hyaluronan expression and cell motility changes. Notably, ERK1/2 and AKT signaling pathways were shown to be downstream of EGF in regulating HAS2 and hyaluronan expression as well as cell migration and invasion., Conclusion: EGF increased the expression of endometriosis-associated hyaluronan and its synthase HAS2, both of which mediated EGF-induced stromal cell migration and invasion in women with endometriosis., (Copyright © 2020 American Society for Reproductive Medicine.

Introduction: the objective of this study was to evaluate the incidence of Chronic Intervillositis of Unknown Etiology (CIUE) at our institution and to report on the pregnancy outcomes based on severity of lesions., Methods: retrospective cohort study including 29 889 perinatal specimens from 27 968 patients. The pathology database at our institution was queried for the keywords "intervillositis" and "CIUE" between February 2006 and April 2019. Histology was re-examined using a standardized diagnostic criterion to confirm diagnosis. Cases in which diagnosis was confirmed were categorized as low grade (5-49% intervillous space involvement) or high grade (≥50% involvement). Interventions and pregnancy outcomes were recorded., Results: The overall prevalence of CIUE is 0.17% (47 of 27 968 patients), with significantly higher prevalence in 1st trimester products of conception compared with 2nd and 3rd trimester specimens (0.38% vs 0.09%; p < 0.0001). A total of 97 specimens were initially diagnosed with chronic intervillositis. 56 out of 97 (57.7%) specimens met our diagnostic criteria for CIUE on review. Pregnancies with confirmed CIUE had significantly higher rates of pregnancy loss compared with pregnancies with chronic intervillositis not meeting our study criteria for CIUE (94% vs 71%; p = 0.003). Pregnancy loss between low grade (42.9%; 24 out of 56 cases of CIUE) and high grade (57.1%; 32 out of 56 cases) CIUE were not significantly different., Discussion: CIUE prevalence is low at 0.17%, but it is associated with pregnancy loss, particularly in the first trimester. High grade disease may be associated with worse pregnancy outcomes than low grade disease., (Copyright © 2020 Elsevier Ltd. All rights reserved.)

Background: Endometriosis is a complex condition that can negatively affect a woman's quality of life, including her sleep. This study aims to assess the multifactorial variables associated with poorer quality of sleep in women with endometriosis. Materials and Methods: Data from the Endometriosis Pelvic Pain Interdisciplinary Cohort (EPPIC) data registry were analyzed for women who underwent surgery at the BC Women's Center for Pelvic Pain and Endometriosis with histopathological confirmation of endometriosis (June 2015 to June 2017). The primary outcome was quality of sleep preoperatively, from the Chronic Pain Sleep Inventory (0-100 VAS). Bivariate analysis and multivariable linear regression were done to determine any significant associations between preoperative patient variables and overall quality of sleep, based on p -value of 0.05. Results: Two hundred and seventy-five women met the study criteria. Poorer overall quality of sleep was independently associated with poorer functional quality of life (EHP-30) (b = -0.18, p  = 0.0026), more depressive symptoms (PHQ-9) (b = -1.62, p  < 0.001), and painful bladder syndrome (PBS) (b = -5.82, p  = 0.035). This indicates that a 1 point increase in the EHP-30 (worsening quality of life), a 1 point increase in the PHQ-9 (worsening depression), and the presence of PBS increased the primary outcome ( i.e ., toward poorer quality of sleep) by 0.18, 1.62, and 5.82 points. Conclusions: Poorer quality of sleep in women with endometriosis is associated with poorer quality of life, more depressive symptoms, and bladder pain. Research into interventions that improve sleep is warranted as part of the management of some women with endometriosis.

Endometriosis is characterized by the presence of ectopic endometrial tissues. Mechanisms of tissue dissemination in endometriosis may be similar to those involved in tumor metastasis. We hypothesize that dysregulation of kisspeptin (KISS1), a metastasis suppressor in endometrial carcinoma, may contribute to the pathogenesis of endometriosis. In this study, we characterized the immunoreactivity of kisspeptin and its receptor, KISS1R, in eutopic and ectopic endometrial tissue of women with and without endometriosis, in proliferative and secretory menstrual cycle phases. Immunohistochemistry was performed using KISS1 and KISS1R antibodies on samples from women with (n = 35) and without (n = 14) endometriosis. Samples from women with endometriosis included eutopic endometrium (n = 20) samples, superficial endometriotic implants (SUP, n = 10) deep infiltrating endometriotic implants (DIE, n = 15), and ovarian endometriomas (OMA, n = 15). Immunoreactivity was quantified using histoscores. KISS1 and KISS1R immunoreactivity was significantly lower in eutopic endometrial stroma of women with versus without endometriosis, regardless of the menstrual cycle phase (P = 0.001 and P = 0.015 respectively). In endometriotic implants, KISS1 levels were significantly lower in both glandular and stromal components of DIE (P < 0.01) and OMA (P < 0.01) compared to SUP. KISS1R immunoreactivity was lower in the glandular component of OMA (P = 0.035) compared to SUP. KISS1 and KISS1R levels are lower in eutopic endometrial stroma from women with versus without endometriosis, consistent with a role for decreased KISS1 expression in the pathogenesis of endometriosis. As deeply invasive lesions showed lower KISS1 levels than superficial lesions, downregulation of KISS1 levels may contribute to implant invasiveness.

Background: Uterine fibroids are common in women and their management is heavily influenced by information gathered through imaging. We aimed to evaluate the type and quality of imaging performed for assessment of uterine fibroids in Canada., Methods: Starting in July 2015, premenopausal women with symptomatic fibroids were enrolled in a prospective, noninterventional, observational registry (Canadian Women With Uterine Fibroids Registry [CAPTURE]) that included 19 Canadian sites. Clinical characteristics were extracted from the baseline visit. We evaluated the association between demographic and clinical variables of interest with regard to imaging type using unadjusted and adjusted logistic regression models., Results: Of 1493 women, 1148 had ultrasonography, 135 had magnetic resonance imaging (MRI), 80 had other types of imaging and 130 did not have imaging reported within 12 months of the baseline visit. After adjusting for demographic and clinical characteristics, patients who underwent MRI had larger fibroids (odds ratio [OR] per 1-cm increase 1.11, 95% confidence interval [CI] 1.05-1.17) and more numerous fibroids (1 v. > 1; OR 1.74, 95% CI 1.14-2.64) compared with those who underwent ultrasonography only. For ultrasonography reporting, quality criteria were met for 268 of 1148 patients (23.3%). There was a difference in the quality of reporting among the 19 sites ( p < 0.001). Logistic regression model accounting for within-site variability showed that reporting results from ultrasonography in the province of Quebec were less likely to meet all quality criteria (OR 0.20, 95% CI 0.06-0.66) and those from sites in more populated cities (≥ 400 000 inhabitants) were more likely to do so (OR 6.15, 95% CI 2.20-17.18)., Interpretation: We determined that imaging modality for fibroids is associated with patient characteristics. The quality of reporting results for ultrasonography of fibroids in Canada falls short of internationally endorsed guidelines and needs improvement., Study Registration: ClinicalTrials.gov, no.

Introduction: Deep dyspareunia is a cardinal symptom of endometriosis, and as many as 40% of people with this condition experience comorbid superficial dyspareunia., Aim: To evaluate the relationship between sexual pain and infertility concerns among women with endometriosis., Methods: This is a cross-sectional study conducted at a university-based tertiary center for endometriosis. 300 reproductive-aged participants in the prospective Endometriosis Pelvic Pain Interdisciplinary Cohort (ClinicalTrials.gov Identifier: NCT02911090) with histologically confirmed endometriosis were included (2013-2017)., Main Outcome Measure: The total score on the infertility concerns module of the Endometriosis Health Profile-30 categorized into 5 groups (0, 1-4, 5-8, 9-12, 13-16)., Results: The odds of infertility concerns did not increase with severity of deep dyspareunia (odds ratio = 1.02, 95% CI: 0.95-1.09, P = .58). However, the odds of infertility concerns increased with severity of superficial dyspareunia (odds ratio = 1.09, 95% CI: 1.02-1.16, P = .011); this relationship persisted after adjusting for endometriosis-specific factors, infertility risk factors, reproductive history, and demographic characteristics (adjusted odds ratio [AOR] = 1.14, 95% CI: 1.06-1.24, P < .001). Other factors in the model independently associated with increased infertility concerns were previous difficulty conceiving (AOR = 2.09, 95% CI 1.04-4.19, P = .038), currently trying to conceive (AOR = 5.23, 95% CI 2.77-9.98, P < .001), nulliparity (AOR = 3.21, 95% CI 1.63-6.41, P < .001), and younger age (AOR = 0.94, 95% CI: 0.89-0.98, P = .005)., Conclusion: Severity of superficial dyspareunia, but not deep dyspareunia, was associated with increased odds of infertility concerns among women with endometriosis. Strengths of the study included the use of a validated measure of infertility concerns and disaggregation of sexual pain into deep and superficial dyspareunia. Limitations included the setting of a tertiary center for pelvic pain, which affects generalizability to fertility clinic and primary care settings. Women experiencing introital dyspareunia, who can have difficulties with achieving penetrative intercourse, may be concerned about their future fertility and should be counselled appropriately.

Endometriosis-associated chronic pelvic pain can at times be a complex problem that is resistant to standard medical and surgical therapies. Multiple comorbidities and central sensitization may be at play and must be recognized with the help of a thorough history and physical examination. If a complex pain problem is identified, most endometriosis expert reviews and guidelines recommend multidisciplinary care. However, there are no specific recommendations about what should be the components of this approach and how that type of team care should be delivered. There is evidence showing the effectiveness of specific interventions such as pain education, physical therapy, psychological therapies, and pharmacotherapies for the treatment of chronic pain. Interdisciplinary team models have been well studied and validated in other chronic pain conditions such as low back pain. The published evidence in support of interdisciplinary teams for endometriosis-associated chronic pain is more limited but appears promising. Based on the available evidence, a model for an interdisciplinary team approach for endometriosis care is outlined., Competing Interests: Dr Allaire reports personal fees from Abbvie, outside the submitted work.

Study Question: Does interleukin-1β (IL-1β) play a role in promoting nerve growth factor expression, neurogenesis and deep dyspareunia in endometriosis?, Summary Answer: IL-1β directly stimulates nerve growth factor (NGF) expression in endometriosis and is associated with local neurogenesis around endometriosis and more severe deep dyspareunia., What Is Known Already: Local nerve density around endometriosis (using the pan-neuronal marker PGP9.5) is associated with deep dyspareunia in endometriosis, mediated in part by NGF expression., Study Design, Size, Duration: This in vitro study included endometriotic tissue samples from 45 patients., Participants/materials, Setting, Methods: This study was conducted in a university hospital affiliated research institute and included 45 women with surgically excised deep uterosacral/rectovaginal endometriosis (DIE, n = 12), ovarian endometriomas (OMA, n = 14) or superficial peritoneal uterosacral/cul-de-sac endometriosis (SUP, n = 19). Immunolocalisation of IL-1β, IL-1 receptor type 1 (IL-1R1), NGF and PGP9.5 in endometriotic tissues was examined by immunohistochemistry (IHC), and the intensity of IHC staining in the endometriotic epithelium and stroma was semi-quantitatively evaluated using the Histoscore method (H-score). For each case, deep dyspareunia was pre-operatively rated by the patient on an 11-point numeric rating scale (0-10). In addition, primary endometriosis stromal cells were isolated and cultured from surgically excised endometriosis. These cells were treated with IL-1β alone or in combination of Anakinra (an inhibitor of IL-1R1), small inference RNA (siRNA) against IL-1R1, siRNA against c-FOS or NGF neutralising antibody. The mRNA and protein levels of target genes (NGF and c-FOS) were assessed by reverse-transcription qPCR and western blot/ELISA, respectively. Furthermore, immunofluorescent microscopy was used to examine the neurite growth of rat pheochromocytoma PC-12 cells, as an in vitro model of neurogenesis., Main Results and the Role of Chance: For IHC, IL-1β expression in the endometriosis epithelium was significantly associated with more severe deep dyspareunia (r = 0.37, P = 0.02), higher nerve fibre bundle density around endometriosis (r = 0.42, P = 0.01) and greater NGF expression by the endometriosis epithelium (r = 0.42, P = 0.01) and stroma (r = 0.45, P = 0.01). In primary endometriosis stromal cells, treatment with exogenous IL-1β significantly increased the mRNA and protein levels of NGF and c-FOS. Pre-treatment with Anakinra, siRNA against IL-1R1, or siRNA against c-FOS, each attenuated IL-1 β-induced increases of NGF expression. In addition, supernatants from IL-1β treated endometriosis stromal cells significantly stimulated PC-12 neurite growth compared to controls, and these effects could be attenuated by pre-treatment with NGF neutralising antibody or Anakinra., Large-Scale Data: N/A., Limitations, Reasons for Caution: We did not have data from cultures of endometriosis glandular epithelium, due to the known difficulties with primary cultures of this cell type., Wider Implications of the Findings: Our study revealed a mechanism for deep dyspareunia in endometriosis, whereby IL-1β stimulates NGF expression, promoting local neurogenesis around endometriosis, which in turn leads to tender pelvic anatomic sites and thus deep-hitting dyspareunia. There may also be potential for drug targeting of IL-1β and/or NGF in the management of endometriosis-associated pain., Study Funding/competing Interest(s): This study was funded by grants from the Canadian Institutes of Health Research (MOP-142273 and PJT-156084).

Research Question: Does initiating levothyroxine treatment based on thyroid-stimulating hormone (TSH) >2.5 mIU/l or thyroid autoimmunity improve pregnancy continuation rates in recurrent pregnancy loss (RPL) patients?, Design: A retrospective cohort study of 1064 RPL patients, in which subjects were classified as either euthyroid (TSH 0.1 to ≤2.5 mIU/l), borderline-subclinical hypothyroid (borderline-SCH, TSH 2.5 to ≤4 mIU/l) or subclinical hypothyroid (SCH, TSH 4 to ≤10 mIU/l). For subjects with ≥2 pregnancy losses and a subsequent pregnancy with known outcome, a comparison was done of the pregnancy continuation rate past 10 weeks of treated and untreated borderline-SCH (n = 98) and untreated euthyroid (n = 279) subjects, and between subjects with positive (n = 18) and negative (n = 206) thyroid peroxidase (TPOAb tests) within the borderline-SCH and euthyroid groups., Results: 72.7% were euthyroid (721/992), 19.4% (192/992) were borderline-SCH, and 5.4% (54/992) were subclinically hypothyroid (SCH). Of 401 women with a subsequent pregnancy of known outcome at 10 gestational weeks, 21% received treatment with levothyroxine. 57.7% of subjects had a TPOAb test, which was positive in 9.25% (37/400) in euthyroid, 16.5% (22/133) in borderline-SCH subjects and 35.3% (12/34) in SCH subjects. Treatment did not improve pregnancy continuation rates in borderline-SCH subjects (P = 0.392). There was no difference in pregnancy outcomes based on TPOAb status and treatment for borderline-SCH subjects (P = 0.4214), or based on TPOAb status for euthyroid subjects (P = 0.2668)., Conclusions: Treatment of hypothyroidism in pregnancy should be initiated based on a TSH >4 mIU/l. Treatment initiation based on thyroid autoimmunity or a TSH >2.5 mIU/l may result in overtreatment., (Copyright © 2019 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.)

Introduction: Deep dyspareunia, a common symptom in endometriosis, has previously been associated with bladder and/or pelvic floor tenderness (BPFT), which suggests a role for central nervous system sensitization. The Central Sensitization Inventory (CSI, 0-100) is a validated self-reported scale for patients with central sensitization., Aim: The objective of this study was to phenotype deep dyspareunia using BPFT and the CSI., Methods: The methods included cross-sectional analysis from a prospective registry from January 2018 to June 2018 at a tertiary center for endometriosis (ClinicalTrials.gov #NCT02911090). Included were women aged 18-50 years with endometriosis (previously surgically diagnosed, current visualized endometrioma on ultrasound, or current palpable or visualized nodule on ultrasound), who were newly or re-referred to the center. Severity of deep dyspareunia was self-reported using an 11-point numeric rating scale (0 = no pain; 10 = worst pain imaginable), categorized as no or low deep dyspareunia (0-4) and high deep dyspareunia (5-10). We identified the subgroup with high deep dyspareunia and presence of BPFT, where we hypothesized a central component of the sexual pain. This subgroup was compared with 2 other subgroups: no or low deep dyspareunia and high deep dyspareunia but no BPFT. The CSI was compared between the groups using analysis of variance, followed by post hoc testing (P < .05)., Main Outcome Measure: The main outcome measure was the CSI score ranging from 0 to 100., Results: Data from 163 women with endometriosis were analyzed. The mean age of this cohort was 36.4 ± 6.8 years, and the mean CSI score was 41.0 ± 18.6. 37 percent (61/163) had high deep dyspareunia and BPFT; 29% (47/163) had high deep dyspareunia and no BPFT; and 34% (55/163) had no or low deep dyspareunia. The CSI significantly differed between the 3 groups (analysis of variance: F = 22.4, P < .001). In post hoc testing, the CSI was higher in women with high deep dyspareunia and BPFT (51.3 ± 16.9), compared with women with no or low deep dyspareunia (30.9 ± 15.4, P < .001) and compared with women with high deep dyspareunia but no BPFT (39.4 ± 17.2, P = .001)., Clinical Implications: The CSI could be used to classify and phenotype patients with endometriosis-associated sexual pain., Strength & Limitations: Strengths include a prospective registry with integrated pain scores, validated questionnaires, and physical examination findings. Limitations include the lack of quantitative sensory testing for central sensitization., Conclusions: In women with endometriosis, the subgroup with high deep dyspareunia and bladder and/or pelvic floor tenderness had a significantly higher score on the CSI than other subgroups, suggesting that this group may have a central component to their sexual pain.

Objective: This study sought to identify factors independently associated with a negative impression of the medical profession in patients with endometriosis who were presenting to a tertiary referral centre., Methods: A cross-sectional analysis was conducted on a prospective data registry between December 2013 and June 2017 at a tertiary referral centre for pelvic pain and endometriosis. The main outcome variable, negative impression about the medical profession, was measured with the four-item subscale of the Endometriosis Health Profile-30 and divided into three groups: no (0), some (1-8), and many (9-16) negative impressions. Patients with a surgical and histological diagnosis of endometriosis were included. Postmenopausal women were excluded. Bivariate analyses determined significant associations (P < 0.05) between variables from the registry and the main outcome. Variables with a significant association were put into ordinal logistic regression with sequential backwards elimination., Results: Negative impression of the medical profession was independently associated with previous surgery that did not help symptoms (adjusted odds ratio [aOR] 1.77; 95% confidence interval [CI] 1.09-2.87; P = 0.021), presentation to an emergency room in the past 3 months (aOR 1.90; 95% CI 1.17-3.07; P = 0.009), and previous visits to a complementary health care provider (aOR 2.16; 95% CI 1.42-3.29; P < 0.0005), while controlling for an endometriosis pain-related morbidity composite variable., Conclusion: Negative perception of the medical profession in women with endometriosis was associated with surgical treatment failure, emergency room use, and accessing complementary health care. Each identified factor offers an opportunity for intervention to improve the perception of the medical profession among women with endometriosis., (Copyright © 2019 The Society of Obstetricians and Gynaecologists of Canada/La Société des obstétriciens et gynécologues du Canada.

Study Question: What are the use patterns and factors associated with combined hormonal contraception (CHC) ineffectiveness or discontinuation due to side-effects in patients with endometriosis and pelvic pain?, Summary Answer: Worse chronic pelvic pain (CPP) severity and pelvic floor myalgia were associated with continuous CHC ineffectiveness, while poorer quality-of-life was associated with continuous CHC discontinuation due to side-effects., What Is Known Already: CHC is a first line of therapy for endometriosis-associated pelvic pain in women. However, some patients state that CHC is ineffective for their pain, while others have to discontinue CHC due to side-effects., Study Design Size Duration: Analysis of a prospective patient database from a tertiary care referral center for patients with endometriosis and pelvic pain between December 2013 and April 2015 was carried out., Participants/materials Setting and Methods: A total of 373 patients of reproductive age with endometriosis from the database were included in the study. Data included patient self-reported questionnaires, physical examination findings and validated instruments. There were four variables of interest: history of cyclical CHC ineffectiveness (yes/no), history of cyclical CHC discontinuation due to side-effects (yes/no), history of continuous CHC ineffectiveness (yes/no) and history of continuous CHC discontinuation due to side-effects (yes/no). The primary outcome was CPP severity for the past 3 months (score of 0-10), and secondary outcomes were other pelvic pain scores, quality-of-life on the Endometriosis Health Profile 30 (EHP-30) and underlying conditions including irritable bowel syndrome, painful bladder syndrome, abdominal wall pain, pelvic floor myalgia and depression, anxiety and pain catastrophizing., Main Results and the Role of Chance: Among the 373 cases in the dataset, prior cyclical CHC use was reported by 228 (61.1%) women, of which 103 (27.6%) stated it was ineffective for their pain and 94 (25.2%) stated they discontinued CHC due to side-effects. Previous continuous CHC use was reported by 175 (46.9%) women, of which 67 (18.0%) stated it was ineffective and 59 (15.8%) stated they discontinued due to side-effects. Worse CPP severity in the last 3 months was associated with a history of continuous CHC ineffectiveness ( P  < 0.001). Poorer quality-of-life was present in women who reported a history of continuous CHC discontinuation due to side-effects ( P  = 0.005). Among the underlying conditions, pelvic floor tenderness (as a marker of pelvic floor myalgia) was associated with CHC ineffectiveness., Limitations and Reasons for Caution: This study involved patient recall and no longitudinal follow-up. Also, we do not have data on the type of side-effect that led to discontinuation. Medication ineffectiveness was reported subjectively by the patient rather than using standardized criteria. Finally, the diagnosis of endometriosis was based on previous surgery or a current nodule or endometrioma on examination/ultrasound; without prospective surgical data on all the patients, it was not possible to do a sub-analysis by current surgical features (e.g. stage)., Wider Implications of the Findings: In women with endometriosis, CHC ineffectiveness was associated with worse CPP and pelvic floor myalgia, which suggests myofascial or nervous system contributors to CPP that does not respond to hormonal suppression. A tender pelvic floor, as a sign of pelvic floor myalgia, may be a clinical marker of patients with endometriosis who are less likely to have an optimal response to hormonal suppression. For women who discontinue CHC due to side-effects, research is needed to help alleviate these side-effects as these patients report worse quality-of-life., Study Funding/competing Interests: This work was supported by a Canadian Institutes of Health Research (CIHR) Transitional Open Operating Grant (MOP-142273) as well as BC Women's Hospital and the Women's Health Research Institute.

Objective: To systematically review and perform a meta-analysis of the risk of ectopic pregnancy in endometriosis., Data Sources: MEDLINE (OVID), Embase (OVID), CINAHL (EBSCO), and Cochrane Library to April 1, 2019. Inclusion criteria were cohort or case-control studies from 1990 onward. Exclusion criteria were cohort studies without controls, case reports or series, or no English full-text., Methods of Study Selection: A total of 1361 titles/abstracts were screened after removal of duplicates, 39 full-texts were requested, and, after 24 studies were excluded, there were 15 studies in the meta-analysis., Tabulation, Integration, and Results: Data were extracted using standardized spreadsheets with 2 independent reviewers, and conflicts were resolved by a third reviewer. We performed random effects calculation of weighted estimated average odds ratio (OR). Heterogeneity and publication bias were assessed with the I 2 metric and funnel plots/Egger's test, respectively. The Ottawa-Newcastle Quality Assessment Scale was used with a cutoff of ≥7 for higher quality. There were 10 case-control studies (17 972 ectopic pregnancy cases and 485 266 nonectopic pregnancy controls) and 5 cohort studies (30 609 women with endometriosis and 107 321 women without endometriosis). For case-control studies, endometriosis was associated with increased risk of ectopic pregnancy with an OR of 2.66 (95% confidence interval [CI] = 1.14-6.21, p = .02). For cohort studies, the OR was 0.95 (95% CI = 0.29-3.11, p = .94), but after post hoc analysis of the studies with a Ottawa-Newcastle score ≥7, the OR was 2.16 (95% CI = 1.67-2.79, p <.001). For both case-control and cohort studies, there was high heterogeneity among studies (I 2  = 93.9% and I 2  = 96.6%, Q test p <.001) but no obvious evidence of systematic bias in the funnel plot, and Egger's test results were not significant (p = .35, p = .70), suggesting no strong publication bias. There were insufficient data to make any conclusions with respect to anatomic characteristics of endometriosis (e.g., stage) or mode of conception (e.g., assisted reproductive technology vs spontaneous)., Conclusion: Possible evidence of an association between endometriosis and ectopic pregnancy was observed (OR = 2.16-2.66). However, these results should be considered with caution, owing to high heterogeneity among studies. Continued research is needed to delineate the pregnancy implications of endometriosis., (Copyright © 2019 AAGL. Published by Elsevier Inc. All rights reserved.)

What is the impact of noncavity-distorting intramural fibroids on live birth rates in in vitro fertilization (IVF) cycles? We searched Embase, MEDLINE, Google Scholar, Cochrane Library, and PUBMED from inception to May 2018. We included studies with women undergoing IVF treatment who had at least one noncavity-distorting intramural fibroid. The studies had to report one or more of the following outcomes: live birth rate as our primary outcome, and implantation rate, clinical pregnancy rate, or miscarriage rate as our secondary outcomes. We excluded studies where women also had submucosal fibroids or had undergone myomectomy. Two authors independently selected studies and extracted data. Methodological quality was assessed using Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. We included 15 studies with 5029 patients. Patients with noncavity-distorting intramural fibroids had 44% lower odds of live birth (estimated average odds ratio [OR] = 0.56, 95% confidence interval [CI] = 0.46-0.69) and 32% lower odds of clinical pregnancy (estimated average OR = 0.68, 95% CI = 0.56-0.83). Subgroup analysis of women with purely intramural fibroids showed significantly lower odds of live birth rates and clinic pregnancy rates. Analysis of prospective and retrospective studies shows that noncavity-distorting intramural fibroids have a significant adverse effect on live birth rates in women undergoing IVF. Further, well-designed prospective studies are needed to investigate whether removal of these fibroids improves IVF outcomes in this population.

Endometriosis and atherosclerotic cardiovascular disease (ASCVD) share similar pathogenic mechanisms. Hence, this systematic review evaluates the association between endometriosis and lifetime ASCVD risk including co-prevalence with dyslipidaemia, atherosclerosis and non-invasive markers of endothelial dysfunction. The electronic databases Embase, PubMed, MEDLINE, Cochrane Register of Trials and ClinicalTrials.gov were systematically searched for relevant articles. Two prospective cohort studies demonstrated an increased lifetime ASCVD risk after controlling for demographic and lifestyle confounders in women with endometriosis, as measured by higher incidence of myocardial infarction (relative risk [RR] 1.52), angiography-confirmed angina (RR 1.91), or requiring coronary artery bypass graft surgery (RR 1.35). Among 10 studies that included 407 patients with surgically proven endometriosis and 557 controls, RR of developing hypercholesterolemia and hypertension were 1.25 and 1.14, respectively, while higher serum lipoprotein a and lower paraoxonase 1 levels were found in women with endometriosis that was negatively correlated with stage of disease (r = -0.74, P < 0.0001). Hence, currently available evidence suggests that women with endometriosis are at higher lifetime risk of developing ASCVD than women without endometriosis. However, robust causal evidence is still lacking and future studies are needed to determine whether women with endometriosis represent a high-risk population for lifelong ASCVD risk., (Copyright © 2019 Reproductive Healthcare Ltd.

Purpose of Review: The purpose of this review is to summarize and highlight recent critical advances in the diagnosis, classification, and management of adenomyosis., Recent Findings: Recent studies have clarified the specific mechanism through which adenomyotic lesions invade the underlying myometrium by epithelial-mesenchymal transition. Correlation studies using diagnostic MRI also strongly support the hypothesis of a different pathogenesis between the inner and outer myometrium forms of adenomyosis. Given advances in diagnostic imaging, several international organizations have also highlighted the importance of classification systems for adenomyosis. Finally, selective progesterone receptor modulators and gonadotropin-releasing hormone antagonists have demonstrated significant promise for treating pelvic pain and bleeding associated with adenomyosis, whereas novel fertility-preserving surgical techniques have been introduced to excise diffuse adenomyotic pathology while maintaining adequate uterine integrity., Summary: Recent attempts at a uniform and reproducible classification system likely represent the first step for the development of a staging system for adenomyosis that can be correlated with the severity of clinical symptoms and promote an individualized therapeutic approach. Simultaneously, further insights into the etiology and pathogenesis as outlined in this review may also help in the development of targeted medical therapies.

Purpose: Deep infiltrating endometriosis (DIE) is defined as an endometriotic lesion penetrating to a depth of >5 mm and is associated with pelvic pain, but the underlying mechanisms are unclear. Our objective is to investigate whether plasminogen activator inhibitor-1 expression (PAI-1) in endometriotic tissues is increased in women with DIE., Methods: In this blinded in vitro study, immunohistochemistry and Histoscore were used to examine the expression of PAI-1 in glandular epithelium (GECs) and stroma (SCs) in a total of 62 women: deep infiltrating uterosacral/rectovaginal endometriosis (DIE; n = 13), ovarian endometrioma (OMA; n = 14), superficial peritoneal uterosacral/cul-de-sac endometriosis (SUP; n = 23), uterine (eutopic) endometrium from women with endometriosis (UE; n = 6), and non-endometriosis eutopic endometrium (UC; n = 6). The following patient characteristics were also collected: age, American Fertility Society stage, hormonal suppression, phase of menstrual cycle, dysmenorrhea score and deep dyspareunia score., Results: PAI-1 expression in GECs and SCs of the DIE group was significantly higher than that of SUP group (p = 0.01, p = 0.01, respectively) and UE group (p = 0.03, p = 0.04, respectively). Interestingly, increased PAI-1 expression in GECs and SCs was also significantly correlated with increased dysmenorrhea (r = 0.38, p = 0.01; r = 0.34, p = 0.02, respectively)., Conclusions: We found higher expression of PAI-1 in DIE, and an association between PAI-1 and worse dysmenorrhea., Competing Interests: Dr. Bedaiwy received lecture fees and served on advisory boards for Abbvie and Allergan, and received funding for research unrelated to the present study from Allergan (CAPTURE fibroid registry).

Endometriosis and atherosclerotic cardiovascular disease (ASCVD) are both essentially diseases of inflammation. It is well established that inflammation is the leading mechanism in the initiation and maintenance of vascular injury and in the development and progression of atherosclerosis. Thus, if women with endometriosis do indeed have increased general inflammation, they are at increased risk of developing microvascular dysfunction and atherosclerosis. Currently available evidence suggests that young female patients with proven endometriosis may be at a higher lifetime risk of developing cardiovascular disease; this may be unrecognized due to the relatively young age of women found to have endometriosis. Other mechanisms proposed to explain the link between endometriosis and ASCVD include similarities in the genetic underpinnings of each condition, including microRNA dysfunction and the association between endometriosis and early menopause, a risk for developing ASCVD. Although physicians today primarily focus on traditional risk factors when evaluating an individual female patient's risk of developing ASCVD, we believe that a history of endometriosis should be included as a possible risk factor and needs further exploration. A better understanding of the mechanisms linking endometriosis with ASCVD will hopefully guide the implementation of new therapies to mitigate the increased cardiovascular disease burden that patients with endometriosis might face., (Copyright © 2019 AAGL.

Study Objective: To evaluate the point-of-care preoperative transvaginal ultrasound (TVUS) sliding sign in comparison with palpation of a nodule on digital pelvic examination for the prediction of pouch of Douglas (POD) obliteration., Design: Analysis of data from a prospective data registry (Canadian Task Force classification II-2)., Setting: A tertiary referral center., Patients: Women with suspected endometriosis who had preoperative pelvic examination and point-of-care TVUS followed by laparoscopic surgery between August 2015 and December 2016., Interventions: Women were preoperatively assessed for the prediction of POD obliteration with pelvic examination for a nodule and point-of-care TVUS uterine/cervix sliding sign., Measurements and Main Results: The study included 269 women, 15.2% (41/269) of whom had POD obliteration at the time of surgery. A preoperative negative sliding sign had a sensitivity of 73.2% (95% confidence interval, 57.1%-85.8%) and a specificity of 93.9% (95% CI, 89.9%-96.6%) in the prediction of POD obliteration compared with preoperative palpation of a nodule on pelvic examination, which had a sensitivity of 24.4% (95% CI, 12.4%-40.3%) and a specificity of 93.4% (95% CI, 89.4%-96.3%). The difference in sensitivity was statistically significant (McNemar test, p <.001). A negative sliding sign was also associated with longer operating times and more difficult surgery including the need for ureterolysis., Conclusion: The point-of-care TVUS sliding sign showed significantly improved sensitivity compared with palpation of a nodule on pelvic examination for the prediction of POD obliteration. Therefore, the point-of-care TVUS sliding sign improves the preoperative assessment of POD disease and thus may lead to more optimal surgical planning in women with suspected endometriosis., (Copyright © 2018 AAGL.

Sperm DNA fragmentation (sDF) has emerged as a valuable tool for evaluating male fertility, yet the relationship between DNA fragmentation in the male gamete and idiopathic recurrent pregnancy loss (RPL) remains a topic of ongoing debate. Hence, a meta-analysis was conducted of 12 prospective and 2 retrospective studies involving 530 men with a history of RPL who underwent sDF testing compared with 639 fertile control participants. The main outcome measures were sDF measured by comet assay, TdT (terminal deoxynucleotidyl transferase)-mediated dUDP nick-end labelling (TUNEL), sperm chromatin dispersion (SCD) or sperm chromatin structure assay. Overall, couples with a history of idiopathic RPL demonstrated higher levels of sDF than fertile couples (average mean difference 11.98, P < 0.001). Subgroup analysis demonstrated a similar average mean difference between the RPL and control groups using SCD compared with TUNEL, while mean paternal age and mean sperm motility in the RPL groups tested by meta-regression demonstrated no significant effect on the mean differences in sDF (P > 0.10). These results support the diagnostic value of sDF over standard semen analysis, as well as a possible paternally derived genetic origin of unexplained RPL. Further prospective studies are required to further assess the predictive utility of sDF for assessing couples with unexplained RPL., (Copyright © 2018 Reproductive Healthcare Ltd.

Introduction: Pelvic pain and vulvar pain are common conditions in women. In this study, we sought to characterize the clinical picture of patients with concurrent pelvic pain and provoked vestibulodynia (PVD)., Aim: To analyze the association between sexual/clinical characteristics and a diagnosis of PVD among women with pelvic pain., Methods: Cross-sectional analysis of a prospective registry at a tertiary referral center for pelvic pain and endometriosis, involving consecutive non-menopausal sexually active patients 18-49 years-old seen by a single gynecologist from January 2016-December 2017. The sample was divided into 2 groups: pelvic pain with PVD; and pelvic pain alone (without PVD)., Main Outcome Measures: Superficial dyspareunia and deep dyspareunia on a 11-point numeric rating scale, and the sexual quality-of-life subscale of the Endometriosis Health Profile-30 (0-100%)., Results: There were 129 patients that met study criteria: one third with pelvic pain and PVD (n = 42) and two-thirds with pelvic pain alone (without PVD) (n = 87). Women with pelvic pain and PVD had significantly more severe superficial dyspareunia ≥7/10 (OR = 12.00 (4.48-32.16), P < .001), more severe deep dyspareunia ≥7/10 (OR = 4.08 (1.83-9.10), P = .001), and poorer sexual quality of life (Endometriosis Health Profile-30 ≥50%) (OR = 4.39 (1.67-11.57), P = .002), compared with the group with pelvic pain alone. Women with pelvic pain and PVD also had more anxiety, depression, and catastrophizing, more frequent tenderness of the bladder and pelvic floor, and more common diagnosis of painful bladder syndrome. On the other hand, there were no significant differences between the 2 groups in terms of dysmenorrhea, chronic pelvic pain, abdominal wall allodynia, positive Carnett test for abdominal wall pain, functional quality of life, endometriosis, and irritable bowel syndrome., Conclusions: In the pelvic pain population, PVD may be associated with more negative impact on dyspareunia, sexual quality of life, and bladder/pelvic floor function, but it may not significantly impact abdominopelvic pain or day-to-day function in general.

Study Objective: To investigate ethnic differences for moderate-to-severe endometriosis., Design: Analysis of a prospective registry (Canadian Task Force classification II-2)., Setting: Tertiary referral center., Patients: A total of 1594 women with pelvic pain and/or endometriosis., Interventions: None MEASUREMENTS AND MAIN RESULTS: On logistic regression, adjusting for potential confounders, East/South East Asians were 8.3 times more likely than whites to have a previous diagnosis of stage III/IV endometriosis before referral (adjusted odds ratio [aOR], 8.33; 95% confidence interval [CI], 3.74-18.57), 2.7 times more likely to have a palpable nodule (aOR, 2.66; 95% CI, 1.57-4.52), 4.1 times more likely to have an endometrioma on ultrasound (aOR, 4.10; 95% CI, 2.68-6.26), and 10.9 times more likely to have stage III/IV endometriosis at the time of surgery at our center (aOR, 10.87; 95% CI, 4.34-27.21)., Conclusion: Moderate-to-severe endometriosis was more common in women with East or South East Asian ethnicity in our tertiary referral center.  This could be explained by East/South East Asians with minimal to mild disease being less likely to seek care or genetic/environmental differences that increase the risk of more severe disease among East/South East Asians.

Objective: To examine temporal trend in maternal mortality/severe morbidity associated with hospitalisation due to ectopic pregnancy., Design: A population-based observational study., Setting and Participants: All women hospitalised for ectopic pregnancy in Washington State, USA, 1987-2014 (n=20 418). The main composite outcome of severe morbidity/mortality included death, sepsis, need for transfusion, hysterectomy and systemic or organ failure, identified by diagnostic and procedure codes from hospitalisation files. Severe morbidity/mortality due to ectopic pregnancy were expressed as incidence ratios among women of reproductive age (15-64 years) and among women hospitalised for ectopic pregnancy. Comparisons were made between 1987-1991 (reference) and 2010-2014 using ratios of incidence ratios (RR) and ratio differences (RD). The Cochran-Armitage test for trend assessed statistical significance; logistic regression was used to obtain adjusted OR (AOR) and 95% CI, adjusted for demographic factors and comorbidity., Results: Hospitalisation for ectopic pregnancy declined from 0.89 to 0.16 per 1000 reproductive age women between 1987-1991 and 2010-2014 (p<0.001). Among reproductive age women, ectopic pregnancy mortality remained stable (0.03 per 100 000); and mortality/severe morbidity increased among women aged 25-34 years (p=0.022). Among women hospitalised for ectopic pregnancy, mortality increased from 0.29 to 1.65 per 1000 between 1987-1991 and 2010-2015 (p=0.06); severe morbidity/mortality increased from 3.85% to 19.63% (RR=5.10, 95% CI 4.36 to 5.98; RD=15.78 per 100 women, 95% CI 13.90 to 17.66; AOR for 1-year change was 1.08, 95% CI 1.07 to 1.08)., Conclusions: Hospitalisation for ectopic pregnancy declined in Washington State, USA, between 1987 and 2014; however, mortality/severe morbidity associated with ectopic pregnancy increased in female population aged 25-34 years., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Controversy exists regarding surgical management of endometriomas in infertile women before in vitro fertilization (IVF) because growing evidence indicates that surgery may impair the ovarian response. The objective of the present systematic review and meta-analysis was to compare surgical and expectant management of endometriomas regarding IVF outcomes. Prospective and retrospective controlled studies were found via the Cochrane Library, Embase, and MEDLINE databases. Thirteen studies (1 randomized controlled trial and 12 observational studies, N = 2878) were pooled, and similar live birth rates were observed in the surgically and expectantly managed groups (odds ratio = 0.83; 95% confidence interval [CI], 0.56-1.22; p = .98). The clinical pregnancy rates (odds ratio = 0.83; 95% CI, 0.66-1.05; p = .86), the number of mature oocytes retrieved, and the miscarriage rates were not statistically different between study groups. However, the total number of oocytes retrieved was lower in the surgery group (mean difference = -1.51; 95% CI, -2.60 to -0.43; p = .02). Findings suggest that surgical management of endometriomas before IVF therapy yields similar live birth rates as expectant management. However, future properly designed randomized controlled trials are warranted., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

Background: Fallopian tube occlusion is a common cause of infertility, but the effect of unilateral tubal block (UTB) on pregnancy rates (PR) after controlled ovarian hyperstimulation and intrauterine insemination (COH-IUI) remains controversial., Objective: To evaluate PR after COH-IUI among infertile women with proximal and distal UTB diagnosed by hysterosalpingogram (HSG), compared against women with bilateral patent tubes experiencing unexplained infertility., Search Strategy: We searched EMBASE, MEDLINE, Google Scholar, Cochrane Library, and PUBMED from inception to 14 January 2018., Selection Criteria: Studies that report PR/cycle or cumulative PR among women with UTB and controls were included., Data Collection and Analysis: Two authors independently selected and extracted study characteristics and data. Methodological quality was assessed using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines., Main Results: Among 2965 patients and 5749 IUI cycles across ten studies, no significant difference in PR/cycle (odds ratio, OR = 0.88; 95% confidence interval, 95% CI = 0.69-1.12) and cumulative PR (OR = 0.80, 95% CI = 0.62-1.04) was observed. Patients with proximal UTB demonstrated similar PR/cycle (OR = 1.06, 95% CI = 0.68-1.66) and cumulative PR (OR = 1.10, 95% CI = 0.75-1.62), compared with controls, whereas patients with distal UTB had significantly lower cumulative PR (OR = 0.49, 95% CI = 0.25-0.97, P = 0.04). Patients with proximal block also demonstrated significantly improved cumulative PR, compared with patients with distal block (OR=2.41, 95% CI = 1.37-4.25, P = 0.002)., Conclusion: Infertile patients with proximal UTB diagnosed by HSG can expect similar pregnancy rates after COH-IUI, compared with those with bilateral tubal patency and unexplained infertility, whereas patients with distal UTB have lower odds of pregnancy. These differences may reflect inherent diagnostic limitations of HSG or differences in underlying pathologies., Tweetable Abstract: Meta-analysis evaluates pregnancy outcomes after COH-IUI in women with unilateral tubal block diagnosed by HSG., (© 2018 Royal College of Obstetricians and Gynaecologists.)

Introduction: Deep dyspareunia is a common symptom in women, including in half of women with endometriosis, but little is known about its response to treatment and predictors of persistent deep dyspareunia over time., Aim: To follow up deep dyspareunia severity over a 1-year prospective cohort at an interdisciplinary center, and to identify baseline predictors of more persistent deep dyspareunia at 1 year., Methods: Prospective 1-year cohort study at a tertiary referral center for pelvic pain and endometriosis, where a range of interdisciplinary treatments are provided at a single center (surgical, hormonal, physical, and psychological therapies). Exclusion criteria were menopause, age >50 years, and never previously sexually active. Primary outcome (deep dyspareunia severity) and secondary outcome (sexual quality of life) were followed up over 1 year. Ordinal logistic regression was performed, controlling for baseline severity of deep dyspareunia, to identify baseline predictors of deep dyspareunia severity at 1 year., Main Outcome Measure: Primary outcome was severity of deep dyspareunia on an 11-point numeric rating scale (0-10), categorized into absent-mild (0-3), moderate (4-6), and severe (7-10); secondary outcome was sexual quality of life measured by the Endometriosis Health Profile-30., Results: 1-year follow-up was obtained for 278 subjects (56% response rate at 1 year; 278/497). Severity of deep dyspareunia improved over the 1 year (McNemar test, P < .0001): the proportion of patients in the severe category decreased from 55.0% to 30.4%, the moderate category remained similar from 17.7% to 25.0%, and the absent-mild category increased from 27.3% to 44.6%. Sexual quality of life also improved (56% to 43% on the sex subscale of the Endometriosis Health Profile-30) (Welch t test, P < .001). On ordinal regression, severity of deep dyspareunia at 1 year was independently associated with younger age (OR = 0.94, 95% CI = 0.91-0.97, P = .008), and with a higher baseline depression score on the Patient Health Questionnaire-9 (OR = 1.07, 95% CI = 1.03-1.11, P = .01)., Clinical Implications: Clinicians should consider employing an interdisciplinary approach for deep dyspareunia, and screening for and treating depression symptoms in these women., Strength & Limitations: Strengths of the study include its prospective nature, and assessment of deep dyspareunia specifically (as opposed to superficial dyspareunia). Limitations include non-randomized design, and the patients lost to follow-up over the 1 year., Conclusion: Over 1 year in an interdisciplinary setting, improvements were observed in deep dyspareunia and sexual quality of life, but younger women and those with more severe depression at baseline had more persistent deep dyspareunia at 1 year.

Background: Uterine fibroids are the most common benign tumor in women. Among those with fibroids, approximately 30% become symptomatic, with abnormal uterine bleeding, pelvic pain, and bulk symptoms. Despite the high prevalence of fibroids, little information is available regarding symptoms, treatment choices, and outcomes for patients., Objective: A Canada-wide patient registry was established to understand the real-world practice. This registry included patient presentation and treatment preferences, health care provider attitudes, and clinical outcomes in the management of symptomatic uterine fibroids., Methods: This study is a prospective, noninterventional, observational patient registry. It will include women diagnosed with uterine fibroids and being managed for symptoms. Participant inclusion criteria were (1) at least 18 years of age, (2) premenopausal with a confirmed diagnosis of uterine fibroids, and associated symptoms, and (3) initiating treatment (drug intervention, procedure intervention, or a combination of both) or watchful waiting. Patients (or legal representative) must understand the nature of the project and provide written informed consent before enrollment. Participant exclusion criteria were (1) they have known or suspected clinically significant pelvic pathology not associated with uterine fibroids, and (2) they are undergoing an emergency hysterectomy at the initial visit. Outcomes will be evaluated in the context of routine clinical practice., Results: Participant recruitment of this registry began in July 2015. This study currently has a total sample of 1500 patients., Conclusions: This registry, a first in Canada, will accumulate evidence on the risks and benefits of watchful waiting, and medical and procedural interventions. It will contribute to enhancing access to treatment options for patients., Trial Registration: ClinicalTrials.gov NCT02580578; https://clinicaltrials.gov/ct2/show/NCT02580578 (Archived by WebCite at http://www.webcitation.org/6yax4Hpvr)., International Registered Report Identifier (irrid): RR1-10.2196/10926., (©Mohamed A Bedaiwy, Peter Janiszewski, Sukhbir S Singh, CAPTURE Steering Committee.

Background: Polycystic ovary syndrome (PCOS) affects between 8 and 18% of women and is the leading cause of female anovulatory infertility. Unfortunately, common treatments for women trying to conceive can be ineffective as well as disruptive or harmful to patients' quality of life. Despite evidence that women with PCOS have expressed the need for alternative fertility treatments, lifestyle interventions incorporating a nutritional plan with supplementation, increased physical activity, and techniques for stress management have not been combined as a program and studied in this population. Literature suggests that each of these individual components can positively influence reproductive hormones and metabolic health., Methods/design: This is a randomized controlled trial which will include 240 women diagnosed with PCOS, according to the Rotterdam criteria, who are trying to conceive. Participants will be randomized to either a comprehensive lifestyle intervention program or prescribed an oral fertility medication, letrozole. These two groups will be further randomized to consume either myo-inositol or a placebo. Participants will be between the ages of 18 and 37 years. Exclusion criteria include women who have already begun fertility treatment, who are currently using myo-inositol or have taken it within the past 3 months, or who are being treated for, or have a history of, an eating disorder. The primary outcome will be the ovulation rate, the secondary outcome will be conception. Other outcomes include miscarriage rates, validated rating measures of overall quality of life (including social, relational, mind/body and emotional sub-categories) and mental health scores (depression, anxiety, and stress)., Discussion: This trial will determine the effectiveness of a structured lifestyle-based comprehensive intervention program for women with PCOS experiencing infertility. In addition, it will determine whether supplementing with myo-inositol provides any further benefit. The objective of this study is to assess a possible non-pharmacological solution to ovulatory dysfunction in these patients and perhaps improve other associated features of PCOS., Trial Registration: ClinicalTrials.gov, ID: NCT02630485 .

Introduction: Deep dyspareunia occurs in half of women with endometriosis, a condition present in 10% of reproductive-age women and associated with negative effects on sexual quality of life (SQoL). However, women with endometriosis can have other clinical factors (eg, superficial dyspareunia, other pelvic pains, and psychological or pain conditions) possibly affecting SQoL., Aims: To determine whether deep dyspareunia is associated with SQoL in women with endometriosis, independent of potential confounders., Methods: This study involved a prospective patient registry of women at a tertiary-level referral center for endometriosis and pelvic pain. Inclusion criteria were (i) referrals to the center recruited into the registry from January 2014 through December 2016 and (ii) subsequent surgery at the center with histologic confirmation of endometriosis. Exclusion criteria included menopausal status, age at least 50 years, never sexually active, or did not answer dyspareunia or SQoL questions. Bi-variable tests and multiple linear regression analysis were performed., Main Outcome Measures: SQoL measured by the 5-item sexual intercourse subscale of the Endometriosis Health Profile-30 (EHP-30) modular questionnaire (0-100%, with higher scores indicating worse SQoL)., Results: Consent rate for the prospective registry was 87%; 277 women met the study criteria (mean age = 34.2 ± 7.1 years). Most women had stage I to II endometriosis at time of surgery (64%), with the remaining having stage III to IV endometriosis. Through regression analysis, worse SQoL (higher EHP-30 sexual intercourse subscale score) was independently associated with: more severe deep dyspareunia (P < .0001), more severe superficial dyspareunia (P < .0001), increased depression (P < .001), higher pain catastrophizing (P = .04), bladder pain syndrome (P = .02), heterosexual orientation (P < .001), and new referral status (P = .02)., Conclusion: In women with endometriosis at a tertiary referral center, more severe deep dyspareunia was associated with worse SQoL, independent of superficial dyspareunia, psychological comorbidities, and other potential confounders.

Introduction: The etiology of endometriosis-associated deep dyspareunia may include direct endometriosis-specific factors (eg, stage or invasiveness of disease) and/or indirect contributors such as bladder/pelvic floor dysfunction (eg, related to myofascial mechanisms or nervous system sensitization)., Aim: This study aimed to determine whether bladder/pelvic floor tenderness and painful bladder syndrome were associated with severity of deep dyspareunia in women with endometriosis, regardless of Stage (I/II vs III/IV) or other endometriosis-specific factors., Methods: Observational study from a prospective patient registry (January 2014 to December 2016) at a tertiary centre for endometriosis. Included were women aged 18 to 49 years who had surgical removal and histopathologic confirmation of endometriosis at the centre. Cases with Stage I/II vs Stage III/IV endometriosis were analyzed separately. Bivariate associations with the primary outcome (severity of deep dyspareunia) were tested for bladder/pelvic floor tenderness, painful bladder syndrome, as well as endometriosis-specific factors identified at the time of laparoscopic surgery (eg, deep infiltrating endometriosis) and demographic factors (eg, age). Multivariable ordinal logistic regression was carried out to adjust for factors associated with the primary outcome., Main Outcome Measure: Primary outcome was severity of deep dyspareunia on an 11-point numeric rating scale, categorized as none/mild (0-3), moderate (4-6), and severe (7-10), from a preoperative self-reported questionnaire., Results: Overall, 411 women had surgically confirmed endometriosis: 263 had Stage I/II and 148 had Stage III/IV endometriosis. Among women with Stage I/II endometriosis, severity of deep dyspareunia was associated with both bladder/pelvic floor tenderness and painful bladder syndrome (AOR = 1.94, 95% CI: 1.11-3.38, P = .019 and AOR = 1.99, 95% CI: 1.15-3.44, P = .013, respectively), independent of endometriosis-specific factors or other factors associated with deep dyspareunia severity. Similar associations were found in women with Stage III/IV endometriosis (bladder/pelvic floor tenderness AOR =2.51, 95% CI: 1.25-5.02, P = .01, painful bladder syndrome: AOR = 1.90, 95% CI: 1.01-3.57, P = .048)., Clinical Implications: Myofascial or nervous system mechanisms may be important for deep dyspareunia in women with endometriosis, even in those with moderate-to-severe disease (Stage III/IV)., Strengths & Limitations: Strengths include the prospective registry, and histological confirmation of endometriosis and staging by experienced endometriosis surgeons. Limitations include assessment of only one pelvic floor muscle (levator ani)., Conclusion: In women with Stage I/II or Stage III/IV endometriosis, severity of deep dyspareunia was strongly associated with bladder/pelvic floor tenderness and painful bladder syndrome, independent of endometriosis-specific factors, which suggests the role of myofascial or sensitization pain mechanisms in some women with deep dyspareunia.

Objective: Parental carriers of balanced structural chromosomal rearrangements such as reciprocal or Robertsonian translocations are at increased risk of recurrent pregnancy loss (RPL) due to the production of gametes with unbalanced non-viable chromosome variants. As a purported means of improving reproductive outcomes in this population, IVF and preimplantation genetic diagnosis (PGD) have been introduced as an alternative to natural conception and prenatal diagnosis. In this study, we evaluate the prevalence and treatment choices of couples with structural chromosomal rearrangement referred to a tertiary care RPL clinic. In addition, we compare the two methods of management in terms of live birth rate., Methods: This is a retrospective chart review of 2321 couples who were referred to a highly specialized RPL clinic for ongoing clinical management between January 2005 and December 2013 (n = 23). Couples who pursued PGD through local fertility centres during this time were also included (n = 13)., Results: Thirty-six couples (1.6%) were found to be parental carriers of a structural chromosomal rearrangement. In this cohort, couples were twice as likely to pursue natural conception compared with IVF with PGD. No significant differences were observed in live birth rate between PGD and clinical management (66.6% vs. 53.3%, P = 0.717). With PGD management, six live birth outcomes were observed, with an incidence of one birth in 5.63 years of follow-up. With clinical management, 24 live birth outcomes were observed, with an incidence of one birth in 4.09 years of follow-up. Mean time to live birth was 17.5 months and 23.3 months in clinical management and PGD, respectively., Conclusions: Among couples presenting to a tertiary RPL clinic, parental carriers of structural chromosomal rearrangement and history of RPL are more likely to pursue natural conception over IVF and PGD. With regards to reproductive outcomes, no significant difference in miscarriage rate, time to live birth, or live birth rate was observed between couples who pursued PGD compared with expectant clinical management., (Copyright © 2018 Society of Obstetricians and Gynaecologists of Canada.

Recurrent pregnancy loss (RPL) is a common, yet elusive, complication of pregnancy. Among couples at high risk of RPL, such as those carrying a structural chromosomal rearrangement, preimplantation genetic diagnosis (PGD) has been proposed as a tool to improve live birth rates and reduce the incidence of miscarriage; however, no clear consensus has been reached on its benefits in this population. This systematic review summarizes existing published research on the effect of PGD on pregnancy outcomes among carriers of chromosomal abnormalities with RPL. A comprehensive search of common databases was conducted, which yielded 20 studies. Meta-analysis was precluded owing to significant heterogeneity between studies. The primary outcome of interest was live birth rate (LBR), and a pooled total of 847 couples who conceived naturally had a LBR ranging from 25-71% compared with 26.7-87% among 562 couples who underwent IVF and PGD. Limitations of the study include lack of large comparative or randomized control studies. Patients experiencing RPL with structural chromosomal rearrangement should be counselled that good reproductive outcomes can be achieved through natural conception, and that IVF-PGD should not be offered first-line, given the unproven benefits, additional cost and potential complications associated with assisted reproductive technology., (Copyright © 2018 Reproductive Healthcare Ltd.

This prospective, double-blind, randomized controlled trial was designed to evaluate the efficacy of a culture temperature of 36.5°C versus 37°C on human embryo development in vitro. A total of 412 women undergoing IVF were randomized to two groups: the oocytes and embryos of the intervention group were cultured at 36.5°C; those of the control group were cultured at 37°C. Although no significant effect of culture temperature was observed on pregnancy or implantation rates, differences were found in embryo development. Embryo culture at 36.5°C was associated with a significantly higher cleavage rate (OR 1.6, 95% CI 1.03 to 2.51), but a lower fertilization rate, fewer high-quality embryos on day 3, a lower blastocyst formation rate on day 5, and fewer high-quality and cryopreserved blastocysts (OR 0.87, 95% CI 0.78 to 0.98), (OR 0.60, 95% CI 0.53 to 0.69), (OR 0.85, 95% CI 0.75 to 0.97), (OR 0.5, 95% CI 0.44 to 0.56) and (OR 0.77, 95% CI 0.68 to 0.88), respectively, compared with 37°C. On the basis of these results, and in the absence of data on the optimal temperature for each stage of embryo development in vitro, we recommend continuation of the use of 37°C for human embryo culture., (Copyright © 2018 Reproductive Healthcare Ltd.

Endometriosis is a common disease characterized by the presence of ectopic endometrial tissue. Although the pathogenesis of endometriosis remains unclear, several factors have been implicated, including the dysregulation of homeobox ( HOX) genes. Our objective was to investigate the localization and immunoreactivity of HOXB4 in endometrial tissues from women with or without endometriosis. We studied samples of eutopic endometrium (EE), endometriomas (Eoma), superficial endometriosis (SE), and deep infiltrating endometriosis (DIE) from 34 women with endometriosis, as well as eutopic endometrium from 38 women without endometriosis (EC). HOXB4 localization and immunoreactivity was assessed using immunohistochemistry and histoscore analysis. Data were analyzed with and without stratification by menstrual cycle phase. HOXB4 protein was present in the nuclei of endometrial glandular epithelial cells but not in stromal cells. HOXB4 immunoreactivity was reduced in DIE samples compared to all other groups. A smaller reduction in HOXB4 immunoreactivity was observed in SE samples compared to EC samples. HOXB4 immunoreactivity was significantly greater in proliferative compared to secretory phase samples in the EC group but not in EE, Eoma, or DIE groups. Among only proliferative phase samples, HOXB4 immunoreactivity was reduced in EE, Eoma, and DIE groups compared to EC. Based on these data, we suggest that an impaired capacity of eutopic and ectopic endometrial tissue to upregulate levels of HOXB4 during the proliferative phase may play a role in the pathogenesis of endometriosis and that further downregulation of HOXB4 may enhance ectopic implant invasiveness.

Background: Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in reproductive age women, yet its clinical presentation shares similarities with several other endocrine disorders such as thyroid disease. Hence, the objective of this study was to further evaluate this association by investigating the clinical, hormonal, and metabolic parameters between subclinical hypothyroidism (SCH) and PCOS., Methods: This is a cross-sectional study conducted in a tertiary care clinic at Cleveland, Ohio, USA. A total of 137 women diagnosed with PCOS by Rotterdam criteria were examined. SCH was defined as thyroid-stimulating hormone >2.5 mIU/L in the absence of symptoms of overt hypothyroidism. The mean age, body mass index (BMI), fasting plasma glucose (FPG), glucose tolerance test, hemoglobin A1c, fasting insulin, a 2 hours insulin level after 75 g glucose load, cholesterol, LDL, HDL, and homeostatic model assessment (HOMA) were compared between women with and without SCH. Logistic regression was used to adjust for age and BMI., Results: Among 137 women with PCOS, 21.9% had SCH. Comparison groups were similar in both age and BMI and there was no difference in the mean values of all endocrine and metabolic parameters tested. However, abnormal FPG levels (OR 3.01; CI: 1.12-8.07. p = 0.03) and abnormal HOMA (OR 3.7; CI: 1.14-12.00. p = 0.03) were more likely in women who had SCH than in women without SCH independent of age and BMI., Conclusions: Women with PCOS and SCH are more likely to have impaired FPG values and impaired insulin sensitivity even after adjusting for age and BMI. Hence, close monitoring of PCOS patients for SCH may be beneficial.

Among the variety of treatment options to improve reproductive outcomes for infertile women with adenomyosis (AD), uterine-conserving surgery has shown varying success. Hence, we conducted a systematic review around the topic of fertility-sparing surgery across 18 studies and 1396 infertile women with focal and diffuse AD. Patients with focal AD showed mean pregnancy and miscarriage rates of 52.7% (range,14.3%-77.5%) and 21.1% (range, 0%-44.4%), respectively, whereas patients with diffuse AD had mean pregnancy and miscarriage rates of 34.1% (range, 9.4%-100%) and 21.7% (range, 12.5%-33.3%), respectively. Uterine rupture and preterm birth were observed in 6.8% (3/44) and 4.5% (2/44) of pregnant patients with diffuse AD versus 0% (0/35) and 10.9% (12/110) of patients with focal AD, respectively. No significant differences were observed between natural conception versus assisted reproductive technology (ART) with or without gonadotropin-releasing hormone agonist pretreatment. Overall, patients with focal AD appeared to have higher pregnancy rates after conservative surgery compared with diffuse AD, whereas a higher incidence of uterine rupture was reported after surgery for diffuse AD. However, significant heterogeneity precludes any direct comparison, and prospective controlled trials are required to further elucidate the benefits of fertility-preserving surgery over medical or expectant management for AD-related infertility. In view of the debatable benefits of conservative surgery and the possible increase in adverse pregnancy outcomes, particularly in cases of diffuse AD, clinicians should consider surgery on a case-by-case basis because it may be appropriate for women with concurrent AD-associated pelvic pain or menorrhagia, younger infertile women who have failed medical management or older women with infertility despite ART, and those with a history of recurrent pregnancy loss or implantation failure., (Copyright © 2018.

Endometriosis is present in 1 in 10 reproductive-age women, and half experience deep dyspareunia (pelvic pain with sexual intercourse). Our objective was to investigate nerve growth factor (NGF) and its receptors (TrkA/p75NTR) in endometriosis-associated deep dyspareunia. A total of 32 women with endometriosis in the posterior pelvic compartment (cul-de-sac/uterosacrals) were included, either with (n = 17) or without (n = 15) deep dyspareunia symptoms confirmed by endovaginal ultrasound-assisted palpation on examination. Expression of NGF, TrkA, and p75NTR in the surgically excised cul-de-sac/uterosacral endometriosis was examined by immunohistochemistry and Histoscore blinded to pain phenotypes. Additionally, endometriotic stromal cells (ESCs; n = 3) from ectopic endometriosis lesions were cultured and incubated with/without NGF and/or Trk inhibitor K252a, followed by expression analysis of prostaglandin-endoperoxide synthase 2 (PTGS-2)/cyclooxygenase 2 (COX-2; reverse transcription quantitative real-time polymerase chain reaction and Western blot) and prostaglandin E2 (PGE2) secretion (enzyme-linked immunosorbent assay). We found that the immunointensity of NGF and TrkA, but not p75NTR, was significantly elevated in endometriotic stroma and epithelium from women with deep dyspareunia compared to women without deep dyspareunia. Nerve growth factor immunoreactivity in the stroma was also significantly associated with deep dyspareunia intensity and local nerve bundle density. In cultured ESCs, NGF significantly increased PTGS-2/COX-2 mRNA and protein levels as well as PGE2 secretion, and these effects could be abolished by pretreatment of Trk inhibitor K252a. In conclusion, elevated NGF levels were associated with deep dyspareunia in women with cul-de-sac/uterosacral endometriosis. This association may be mediated by increased nerve bundle density and by COX-2/PGE2 stimulation via Trk receptor. Nerve growth factor signaling may play an important role in endometriosis-associated sexual pain.

Objective: No standardization of quality of operative reporting currently exists, and this represents a missed opportunity for communication among health care providers. This study proposed a method to improve operative notes by structuring the findings by six anatomical zones of the pelvis. Objective I was to validate the method of documenting six zones of the pelvis by using intraoperative photography. Objective II was to compare this method with dictations from operative reports created before introducing this method., Methods: This retrospective cohort study evaluated pre- and post-intervention results of using six zones to guide operative reporting. Reports were collected from participating surgeons and were scored using a validated scoring tool. Each participant was taught to photograph six zones and use the zones in the operative report. Pre- and post-intervention cases were compared using generalized linear mixed models., Results: Scores of study participants using the zones were significantly higher than those without (P <0.0001). Surgeons showed an ability to improve their reporting. The detail illustrated in the cases was qualitatively richer, and the anatomy within the six zones was referenced more frequently., Conclusion: Compared with reports without the technique, incorporating the six zones greatly enhances operative reporting and likely would improve communication among care providers. More reliable communication of intraoperative findings has the potential to enhance the value of laparoscopy greatly as a diagnostic tool across gynaecological subspecialties., (Copyright © 2018 Society of Obstetricians and Gynaecologists of Canada.

Background: Minimally invasive surgery is the preferred approach for performing many gynecologic procedures. Occasionally, supraumbilical port placement may be preferable to optimize visibility and maneuverability although the risks of complications are less well characterized compared to umbilical entry., Methods: We conducted a retrospective review of computed tomograms from 92 patients to evaluate the anatomic considerations for umbilical and supraumbilical port entry based on patient age, body mass index (BMI), parity, abdominal wall thickness, and distance to the great vessels., Results: Supraumbilical entry was not associated with differences in distance to the great vessels compared to the umbilicus. However, supraumbilical location and BMI were associated with greater abdominal wall thickness. Age and BMI were associated with greater distance to the great vessels, while age was associated with thinner abdominal wall. Multiple linear regression confirmed independent effects of age and BMI. No association between parity and distance to retroperitoneal vessels was observed., Conclusion: Younger patients may be at increased risk for great vessel injury and pre-peritoneal insufflation. Obese patients may be at risk for pre-peritoneal insufflation, while patients with BMI < 30, particularly with a skin-to-aorta distance < 7 cm, may be at an increased risk for great vessel injury. Surgeons should consider these factors when considering supraumbilical port entry., (© 2018 S. Karger AG, Basel.)

Background: Chronic pelvic pain affects ∼15% of women, and presents a challenging problem for gynecologists due to its complex etiology involving multiple comorbidities. Thus, an interdisciplinary approach has been proposed for chronic pelvic pain, where these multifactorial comorbidities can be addressed by different interventions at a single integrated center. Moreover, while cross-sectional studies can provide some insight into the association between these comorbidities and chronic pelvic pain severity, prospective longitudinal cohorts can identify comorbidities associated with changes in chronic pelvic pain severity over time., Objective: We sought to describe trends and factors associated with chronic pelvic pain severity over a 1-year prospective cohort at an interdisciplinary center, with a focus on the role of comorbidities and controlling for baseline pain, demographic factors, and treatment effects., Study Design: This was a prospective 1-year cohort study at an interdisciplinary tertiary referral center for pelvic pain and endometriosis, which provides minimally invasive surgery, medical management, pain education, physiotherapy, and psychological therapies. Exclusion criteria included menopause or age >50 years. Sample size was 296 (57% response rate at 1 year; 296/525). Primary outcome was chronic pelvic pain severity at 1 year on an 11-point numeric rating scale (0-10), which was categorized for ordinal regression (none-mild 0-3, moderate 4-6, severe 7-10). Secondary outcomes included functional quality of life and health utilization. Baseline comorbidities were endometriosis, irritable bowel syndrome, painful bladder syndrome, abdominal wall pain, pelvic floor myalgia, and validated questionnaires for depression, anxiety, and catastrophizing. Multivariable ordinal regression was used to identify baseline comorbidities associated with the primary outcome at 1 year., Results: Chronic pelvic pain severity decreased by a median 2 points from baseline to 1 year (6/10-4/10, P < .001). There was also an improvement in functional quality of life (42-29% on the pain subscale of the Endometriosis Health Profile-30, P < .001), and a reduction in subjects requiring a physician visit (73-36%, P < .001) or emergency visit (24-11%, P < .001) in the last 3 months. On multivariable ordinal regression for the primary outcome, chronic pelvic pain severity at 1 year was independently associated with a higher score on the Pain Catastrophizing Scale at baseline (odds ratio, 1.10; 95% confidence interval, 1.00-1.21, P = .04), controlling for baseline pain, treatment effects (surgery), age, and referral status., Conclusion: Improvements in chronic pelvic pain severity, quality of life, and health care utilization were observed in a 1-year cohort in an interdisciplinary setting. Higher pain catastrophizing at baseline was associated with greater chronic pelvic pain severity at 1 year. Consideration should be given to stratifying pelvic pain patients by catastrophizing level (rumination, magnification, helplessness) in research studies and in clinical practice., (Copyright © 2017 Elsevier Inc.

Objective: To evaluate the effect of culturing human embryos in vitro in 3.5% oxygen (O 2 ) concentration., Design: Comparative study., Setting: Private IVF center., Patient(s): The study included 558 women in two groups., Intervention(s): After intracytoplasmic sperm injection (ICSI), women's oocytes were assigned to undergo cultivation in either 3.5% O 2 concentration (intervention) or 5% O 2 level (control group), continuously, from day 0 through day 5 or 6., Main Outcome Measure(s): Clinical pregnancy rate (PR) after ET., Result(s): There were significantly higher fertilization and cleavage rates in the 3.5% O 2 group (odds ratio [OR] 1.72, 95% confidence interval [CI] 1.53-1.93) and (OR 3.74, 95% CI 2.30-6.07) than in the 5% O 2 group. The compaction rate on day 3, and the number of formed, high-quality and cryopreserved blastocysts on day 5 were significantly lower in 3.5% O 2 than in 5% O 2 concentration ([OR 0.81, 95% CI 0.69-0.91], [OR 0.40, 95% CI 0.36-0.46], [OR 0.32, 95% CI 0.28-0.37] and [OR 0.47, 95% CI 0.40-0.54]), respectively. Culturing embryos in 3.5% O 2 concentration led to significantly lower rates of biochemical pregnancy, clinical PR, and implantation ([OR 0.66, 95% CI 0.47-0.92], [OR 0.60, 95% CI 0.43-0.84] and [OR 0.61, 95% CI 0.46-0.81]), respectively., Conclusion(s): Culturing human embryos, continuously from day 0 to 5 or 6, in 3.5% O 2 concentration is associated with significantly lower blastocyst formation rate and clinical outcomes parameters, but rather with significantly higher rates of fertilization and cleavage. Whether these findings hold true for other patient populations and culture media brands remain unknown., (Copyright © 2017 American Society for Reproductive Medicine. Published by Elsevier Inc.

Introduction: Deep dyspareunia negatively affects women's sexual function. There is a known association between deep dyspareunia and endometriosis of the cul-de-sac or uterosacral ligaments in reproductive-age women; however, other factors are less clear in this population., Aim: To identify anatomic sites and associated clinical factors for deep dyspareunia in reproductive-age women at a referral center., Methods: This study involved the analysis of cross-sectional baseline data from a prospective database of 548 women (87% consent rate) recruited from December 2013 through April 2015 at a tertiary referral center for endometriosis and/or pelvic pain. Exclusion criteria included menopausal status, age at least 50 years, previous hysterectomy or oophorectomy, and not sexually active. We performed a standardized endovaginal ultrasound-assisted pelvic examination to palpate anatomic structures for tenderness and reproduce deep dyspareunia. Multivariable regression was used to determine which tender anatomic structures were independently associated with deep dyspareunia severity and to identify clinical factors independently associated with each tender anatomic site., Main Outcome Measure: Severity of deep dyspareunia on a numeric pain rating scale of 0 to 10., Results: Severity of deep dyspareunia (scale = 0-10) was independently associated with tenderness of the bladder (b = 0.88, P = .018), pelvic floor (levator ani) (b = 0.66, P = .038), cervix and uterus (b = 0.88, P = .008), and cul-de-sac or uterosacral ligaments (b = 1.39, P < .001), but not with the adnexa (b = -0.16, P = 0.87). The number of tender anatomic sites was significantly correlated with more severe deep dyspareunia (Spearman r = 0.34, P < .001). For associated clinical factors, greater depression symptom severity was specifically associated with tenderness of the bladder (b = 1.05, P = .008) and pelvic floor (b = 1.07, P < .001). A history of miscarriage was specifically associated with tenderness of the cervix and uterus (b = 2.24, P = .001). Endometriosis was specifically associated with tenderness of the cul-de-sac or uterosacral ligaments (b = 3.54, P < .001)., Conclusions: In reproductive-age women at a tertiary referral center, deep dyspareunia was independently associated not only with tenderness of the cul-de-sac and uterosacral ligaments but also with tenderness of the bladder, pelvic floor, and cervix and uterus.

Objective: To evaluate the efficacy of a dry versus humidified incubator on human embryo development ex vivo., Design: Prospective, double-blind, randomized, controlled trial., Setting: Private fertility centers., Patient(s): A total of 297 women undergoing in vitro fertilization randomized into two groups., Intervention(s): From days 0 to day 5 or 6 of culture, intervention group embryos exposed to dry culture and control group embryos exposed to humidified culture., Main Outcome Measure(s): Subsequent ongoing pregnancy rate., Result(s): After transfer of embryos, there were statistically significantly lower rates of clinical and ongoing pregnancy in the dry culture arm than in the humidified culture arm (odds ratio [OR] 0.57; 95% confidence interval [CI], 0.36-0.91; versus OR 0.54; 95% CI, 0.34-0.85). On day 3 of culture, embryo quality and compaction were lower in the dry culture group (OR 0.38; 95% CI, 0.32-0.45) than in the group exposed to humidified culture (OR 0.23; 95% CI, 0.19-0.27). On day 5 of culture, embryos in dry culture had a lower rate of blastocyst formation (OR 0.39; 95% CI, 0.33-0.46), quality (OR 0.34; 95% CI, 0.29-0.40), and cryopreservation (OR 0.41; 95% CI, 0.35-0.48)., Conclusion(s): In this study, human embryos cultivated ex vivo in a dry incubator had statistically significantly decreased implantation and clinical and ongoing pregnancy rates. Our findings indicate the need for larger multicenter, randomized, controlled trials., Clinical Trial Registration Number: NCT01695096., (Copyright © 2017 American Society for Reproductive Medicine.

Introduction: Although there has been a growing concern over the possible damaging effect of salpingectomy on ovarian reserve, this issue remains uncertain. The purpose of this meta-analysis was to test the hypothesis that salpingectomy may compromise ovarian reserve., Material and Methods: A detailed search was conducted using MEDLINE, Embase, Dynamed Plus, ScienceDirect, TRIP database and the Cochrane Library from January 2000 to November 2016. All cohort, cross-sectional and randomized controlled studies investigating changes in circulating anti-Müllerian hormone (AMH) after salpingectomy were considered. Thirty-seven studies were identified, of which eight were eligible. Data were extracted and entered into RevMan software for calculation of the weighted mean difference (WMD) and 95% CI. Two groups of studies were analyzed separately: group 1 (six studies, n = 464) comparing data before and after salpingectomy and group 2 (two studies) comparing data in women who have undergone salpingectomy (n = 169) vs. healthy controls (n = 154)., Results: Pooled results of group 1 studies showed no statistically significant change in serum AMH concentration after salpingectomy (WMD, -0.10 ng/mL; 95% CI -0.19 to 0.00, I 2 = 0%). Similarly, meta-analysis of group 2 showed no statistically significant difference in serum AMH concentration between salpingectomy group and controls (WMD, -0.11 ng/mL; 95% CI -0.37 to 0.14, I 2 = 77%). Subgroup analyses based on laterality of surgery, type of AMH kit and participants' age (<40 years) still showed no statistically significant changes in circulating AMH., Conclusion: Salpingectomy does not seem to compromise ovarian reserve in the short-term. However, the long-term effect of salpingectomy on ovarian reserve remains uncertain., (© 2017 Nordic Federation of Societies of Obstetrics and Gynecology.)
