Abstract

ObjectiveTo determine the reproducibility of the World Health Organization Fifth Edition (WHO5) strict grading methodology by comparing the percentage of morphologically normal sperm (PNS) recorded by the core laboratory with results obtained at the fertility centers participating in a multisite clinical trial.DesignSecondary cohort analysis of data from the Males, Antioxidants, and Infertility trial.SettingFertility centers.PatientsSemen values of 171 men participating in a multicenter, double-blind, randomized, placebo-controlled trial evaluating the effect of antioxidants on male fertility.InterventionsNot applicable.Main outcome measuresStrict morphology expressed as PNS as determined at each fertility center and the core central laboratory for the same semen sample.ResultsNo correlation was found in the PNS values for the same semen sample between the core laboratory and fertility center laboratories either as a group or by individual site. Interobserver agreement was similarly low (κ = 0.05 and 0.15) between the core and fertility laboratories as a group for strict morphology, categorized by the WHO5 lower reference limits of 4% and 0, respectively. Moderate agreement was found between the core and 2 individual fertility laboratories for the cutoff value of 0 (κ = 0.42 and 0.57). The remainder of the comparisons demonstrated poor to fair agreement.ConclusionsStrict morphology grading using the WHO5 methodology demonstrated overall poor reproducibility among a cohort of experienced fertility laboratories. This lack of correlation and agreement in the PNS values calls into question the reproducibility, and thereby the potential applicability, of sperm strict morphology testing.

Abstract

ObjectiveTo examine the factors associated with increased deoxyribonucleic acid fragmentation index (DFI), evaluate the pregnancy outcomes of men with increased DFI, and compare three independent DFI assays.DesignSecondary analysis.SettingNine US-based fertility centers.PatientsInfertile men (N = 147) with sperm concentration ≤15 × 106/mL, motility ≤40%, or normal morphology ≤4% were enrolled. The female partners were ovulatory, ≤40 years old, and had documented tubal patency.InterventionsAt a baseline visit, the men provided a semen sample. The couples attempted conception without assistance for 3 months and with ovarian stimulation and intrauterine insemination in the subsequent 3 months.Main outcome measuresThe DFI was analyzed using the sperm chromatin structure assay (SCSA) with increased DFI defined as >30%. The predictors of increased DFI were determined by a multivariable linear regression model. The pregnancy outcomes were compared using the χ2 test. The independent DFI assays (SCSA, deoxynucleotidyl transferase-mediated dUTP nick end labeling, and Comet) were compared with Pearson and Spearman correlations.ResultsThe 19% of men with increased DFI were older (36.0 vs. 33.0 years) and had lower total sperm motility (38.2% ± 20.5% vs. 45.2% ± 15.6%). Increased male age was found to be a significant predictor of DFI (0.75, 95% confidence interval [0.06, 1.45]). Increased DFI was not associated with conception or live birth. There was a modest correlation of the deoxynucleotidyl transferase-mediated dUTP nick end labeling assay with the SCSA (r = 0.34) and Comet assay (r = 0.19).ConclusionsOlder age was associated with increased DFI among infertile men. The DFI assays were only weakly correlated, indicating a standard definition of DFI is needed to truly interrogate how sperm deoxyribonucleic acid fragmentation impacts male fertility.

Abstract

OBJECTIVE:Endometriosis is a chronic, estrogen dependent condition that affects 5-10% of reproductive aged women and is associated with pelvic pain and infertility. As the approach to therapy shifts from surgical ablation to pharmacological control, a non-surgical mode of diagnosis would be desirable. The ENDOmarker study was designed by the NICHD Reproductive Medicine Network (RMN) to obtain well characterized and phenotyped bio specimens in a standardized fashion from women with and without endometriosis. DESIGN:Development of a diagnostic test. SETTING:Academic medical centers. PATIENTS:This study will enroll up to 500 participants, and follow them for up to 5 months. Included subjects are aged 18-44, scheduled to undergo gynecologic surgery (laparoscopy/laparotomy) for clinical reasons. INTERVENTIONS:Presence and stage of endometriosis (or its absence) is characterized by visual examination at the time of surgery. Subjects will undergo extensive clinical evaluation pre-operatively and at visits one and four months postoperatively. Endometrial biopsy, blood, urine and disease specific questionnaires will be collected at each visit. MAIN OUTCOME:Samples will be placed in a bio-repository to be used to validate and optimize the clinical use of genomic classifiers of the endometrium alone or in combination with serum cytokines as a non-surgical composite marker of endometriosis. CONCLUSION:This protocol can serve as a reference for objective collection of high quality bio specimens for discovery or validation of potential nonsurgical diagnosis of presence or severity of disease.

Abstract

The double burden of under- and overnutrition profoundly affects human health globally. According to the World Health Organization, obesity and diabetes rates have almost doubled worldwide since 1980, and, in 2011, more than 40 million children under 5 years of age were overweight. Ecologic factors, parental genetics and fitness, and the intrauterine environment significantly influence the likelihood of offspring developing the dysmetabolic diathesis of obesity. This report examines the effects of these factors, including preconception, intrauterine and postnatal energy balance affecting programming of transgenerational transmission, and development of chronic diseases later in life-in particular, diabesity and its comorbidities.

Abstract

Background Women with obesity and infertility are counseled to lose weight prior to conception and infertility treatment to improve pregnancy rates and birth outcomes, although confirmatory evidence from randomized trials is lacking. We assessed whether a preconception intensive lifestyle intervention with acute weight loss is superior to a weight neutral intervention at achieving a healthy live birth. Methods and findings In this open-label, randomized controlled study (FIT-PLESE), 379 women with obesity (BMI [greater than or equal to] 30 kg/m.sup.2) and unexplained infertility were randomly assigned in a 1:1 ratio to 2 preconception lifestyle modification groups lasting 16 weeks, between July 2015 and July 2018 (final follow-up September 2019) followed by infertility therapy. The primary outcome was the healthy live birth (term infant of normal weight without major anomalies) incidence. This was conducted at 9 academic health centers across the United States. The intensive group underwent increased physical activity and weight loss (target 7%) through meal replacements and medication (Orlistat) compared to a standard group with increased physical activity alone without weight loss. This was followed by standardized empiric infertility treatment consisting of 3 cycles of ovarian stimulation/intrauterine insemination. Outcomes of any resulting pregnancy were tracked. Among 191 women randomized to standard lifestyle group, 40 dropped out of the study before conception; among 188 women randomized to intensive lifestyle group, 31 dropped out of the study before conception. All the randomized women were included in the intent-to-treat analysis for primary outcome of a healthy live birth. There were no significant differences in the incidence of healthy live births [standard 29/191(15.2%), intensive 23/188(12.2%), rate ratio 0.81 (0.48 to 1.34), P = 0.40]. Intensive had significant weight loss compared to standard (-6.6 ± 5.4% versus -0.3 ± 3.2%, P < 0.001). There were improvements in metabolic health, including a marked decrease in incidence of the metabolic syndrome (baseline to 16 weeks: standard: 53.6% to 49.4%, intensive 52.8% to 32.2%, P = 0.003). Gastrointestinal side effects were significantly more common in intensive. There was a higher, but nonsignificant, first trimester pregnancy loss in the intensive group (33.3% versus 23.7% in standard, 95% rate ratio 1.40, 95% confidence interval [CI]: 0.79 to 2.50). The main limitations of the study are the limited power of the study to detect rare complications and the design difficulty in finding an adequate time matched control intervention, as the standard exercise intervention may have potentially been helpful or harmful. Conclusions A preconception intensive lifestyle intervention for weight loss did not improve fertility or birth outcomes compared to an exercise intervention without targeted weight loss. Improvement in metabolic health may not translate into improved female fecundity. Trial registration ClinicalTrials.gov NCT02432209., Author(s): Richard S. Legro 1,*, Karl R. Hansen 2, Michael P.

Abstract

Background: Currently, the precise mechanisms that underline male infertility are still unclear. Accumulating data implicate non‐coding RNA cargo of seminal plasma extracellular vesicles due to their association with poor semen quality and higher expression levels relative to vesicle‐free seminal plasma. Method: We assessed sperm‐free seminal plasma extracellular vesicle non‐coding RNA profiles from 91 semen samples collected from male participants of couples seeking infertility treatment. Men were classified into two groups (poor, n = 32; normal, n = 59) based on World Health Organization semen cutoffs. Small RNA sequencing reads were mapped to standard biotype‐specific transcriptomes in the order micro RNA > transfer RNA > piwi‐interacting RNA > ribosomal RNA > ribosomal RNA > circular RNA > long non‐coding RNA using STAR. Differential expression of normalized non‐coding RNA read counts between the two groups was conducted by EdgeR (Fold change ≥1.5 and (false discovery rate [FDR] < 0.05). Result: Small RNA sequencing identified a wide variety of seminal plasma extracellular vesicle non‐coding RNA biotypes including micro RNA, ribosomal RNAs, piwi‐interacting RNAs, transfer RNA, long non‐coding RNAs as well as circular RNAs, and fragments associated with pseudogenes, and nonsense‐mediated decay. The expression levels of 57 seminal plasma extracellular vesicle non‐coding RNAs (micro RNA: 6, piwi‐interacting RNA: 4, ribosomal RNA: 6, circular RNA: 34, and long non‐coding RNA: 7) were altered in men with poor semen quality relative to normal semen parameters, many (60%) of which were circular RNA species. Ontology analysis of differentially expressed micro RNAs and circular RNAs showed enrichment in functional terms related to cellular communication and early development. Conclusion: This is the first study to generate comprehensive seminal plasma extracellular vesicle non‐coding RNA profiles in a clinical setting and to determine the differences between men with normal and abnormal semen parameters. Thus, our study suggests that seminal plasma extracellular vesicle non‐coding RNAs may represent novel biomarkers of male reproductive phenotypes. [ABSTRACT FROM AUTHOR]

Abstract

Purpose: Varicocele is a common problem among infertile men. Varicocele repair (VR) is frequently performed to improve semen parameters and the chances of pregnancy. However, there is a lack of consensus about the diagnosis, indications for VR and its outcomes. The aim of this study was to explore global practice patterns on the management of varicocele in the context of male infertility. Materials and Methods: Sixty practicing urologists/andrologists from 23 countries contributed 382 multiple-choice-questions pertaining to varicocele management. These were condensed into an online questionnaire that was forwarded to clinicians involved in male infertility management through direct invitation. The results were analyzed for disagreement and agreement in practice patterns and, compared with the latest guidelines of international professional societies (American Urological As- sociation [AUA], American Society for Reproductive Medicine [ASRM], and European Association of Urology [EAU]), and with evidence emerging from recent systematic reviews and meta-analyses. Additionally, an expert opinion on each topic was provided based on the consensus of 16 experts in the field. Results: The questionnaire was answered by 574 clinicians from 59 countries. The majority of respondents were urologists/ uro-andrologists. A wide diversity of opinion was seen in every aspect of varicocele diagnosis, indications for repair, choice of technique, management of sub-clinical varicocele and the role of VR in azoospermia. A significant proportion of the re- sponses were at odds with the recommendations of AUA, ASRM, and EAU. A large number of clinical situations were identi- fied where no guidelines are available. Conclusions: This study is the largest global survey performed to date on the clinical management of varicocele for male in- fertility. It demonstrates: 1) a wide disagreement in the approach to varicocele management, 2) large gaps in the clinical prac- tice guidelines from professional societies, and 3) the need for further studies on several aspects of varicocele management in infertile men.

Abstract

Increasing female age is accompanied by a corresponding fall in her fertility. This decline is influenced by a variety of factors over an individual's life course including background genetics, local environment and diet. Studying both coding and non-coding RNAs of the embryo could aid our understanding of the causes and/or effects of the physiological processes accompanying the decline including the differential expression of sub-cellular biomarkers indicative of various diseases. The current study is a post-hoc analysis of the expression of trophectoderm RNA data derived from a previous high throughput study. Its main aim is to determine the characteristics and potential functionalities that characterize long non-coding RNAs. As reported previously, a maternal age-related component is potentially implicated in implantation success. Trophectoderm samples representing the full range of maternal reproductive ages were considered in relation to embryonic implantation potential, trophectoderm transcriptome dynamics and reproductive maternal age. The long non-coding RNA (lncRNA) biomarkers identified here are consistent with the activities of embryo-endometrial crosstalk, developmental competency and implantation and share common characteristics with markers of neoplasia/cancer invasion. Corresponding genes for expressed lncRNAs were more active in the blastocysts of younger women are associated with metabolic pathways including cholesterol biosynthesis and steroidogenesis.
