Hydrosalpinx is a disease characterized by the obstruction of the salpinx, with progressive accumulation in the shape of a fluid-filled sac at the distal part of the tuba uterina, and closed to the ovary. Women with hydrosalpinges have lower implantation and pregnancy rates due to a combination of mechanical and chemical factors thought to disrupt the endometrial environment. Evidence suggests that the presence of hydrosalpinx reduces the rate of pregnancy with assisted reproductive technology. The main aim of the present is review to make an overview of the possible effects of hydrosalpinx on in vitro fertilization (IVF). We conducted a literature search on the PubMed, Ovid MEDLINE, and Google Scholar data bases regarding hydrosalpinx and IVF outcomes. Hydrosalpinx probably has a direct toxic effect on sperm motility and on the embryos. In addition, the increasing liquid inside the salpinges could alter the mechanisms of endometrial receptivity. The window of endometrial receptivity is essential in the implantation of blastocysts, and it triggers multiple reactions arising from the endometrium as well as the blastocysts. Hydrosalpinx could influence the expression of homeobox A10 ( HOXA10 ) gene, which plays an essential role in directing embryonic development and implantation. Salpingectomy restores the endometrial expression of HOXA10 ; therefore, it may be one mechanism by which tubal removal could result in improved implantation rates in IVF. In addition, salpingectomy does not affect the ovarian response, nor reduces the antral follicle count. Further studies are needed to establish the therapeutic value of fluid aspiration under ultrasonographic guidance, during or after oocyte retrieval, in terms of pregnancy rate and ongoing pregnancy., Competing Interests: The authors have no conflict of interests to delcare., (Federação Brasileira de Ginecologia e Obstetrícia.

Purpose: To evaluate the effectiveness, efficiency, and safety of a transnational gamete donation (TGD) programme based on the shipping of vitrified donor oocytes., Methods: A retro-prospective observational study was conducted in the Assisted Reproductive Technology Center of the University Hospital of Florence, Italy. The study population included 622 consecutive donor oocyte cycles. A mean number of 6 vitrified oocytes per couple were shipped from two Spanish biobanks. In the receiving centre, gametes were warmed and inseminated and the subsequent embryo transfer (ET) was performed. The main outcome measurement was LBR. Secondary outcomes included oocyte survival rate, ICSI damage rate, normal fertilization, cleavage, and implantation rate (IR) in both 'fresh' and cryotransfer cycles., Results: A total number of 3536 mature oocytes were warmed with 81.4% surviving oocytes. 2PN oocytes were 1941 with an ICSI normal fertilization rate of 70.4% and a cleavage rate of 93.4%; 857 day-3 embryos were transferred in 498 women, 63 blastocysts in 44. Couples with at least one vitrified embryo were 181 (32.3%). IR was 25.1% and 33.1% for day-3 ET and blastocyst stage respectively. Crude pregnancy rate and LBR after the first ET were 35.5% and 27% correspondingly with a conservative cumulative LBR of 34% and an optimal LBR of 51.4%., Conclusion: Imported vitrified donor oocytes retain their competence and are capable of resulting in ongoing pregnancies and healthy babies in a proportion comparable to other existing systems as egg donation with vitrification/warming in the same laboratory and transnational fresh oocyte donation.

Research Question: To evaluate pre-existing comorbidities, obstetric risk factors and adverse obstetric and neonatal outcomes in pregnancies conceived by oocyte donation, compared with naturally conceived pregnancies or by conventional IVF/intracytoplasmic sperm injection (IVF/ICSI)., Design: This retrospective single-centre contemporary cohort study reviewed data from singleton deliveries at the University Hospital of Careggi, Florence, from 2009 to 2017. Maternal and perinatal outcomes were analysed., Results: The study included 25,851 pregnancies and newborns: 276 (1.1%) children were conceived after oocyte donation, 925 (3.6%) after IVF/ICSI and 24,650 (95.4%) after natural conception. Women in the oocyte donation group were significantly older compared with IVF/ICSI and natural conception groups (P < 0.0001) and had a higher prevalence of chronic hypertension compared with the natural conception group (P = 0.0090). They were administered anticoagulant medications more frequently during pregnancy. The incidence of gestational hypertension was significantly higher than in natural conception (aOR 3.6) and IVF/ICSI pregnancies (aOR 2.7). The incidence of Caesarean section in oocyte donation pregnancies was higher than in natural conception and IVF/ICSI groups (aOR 3.4 and 2.3, respectively). An 11-fold increased risk of post-partum haemorrhage (PPH) was found in oocyte donation versus natural conception and an almost four-fold increased risk was found in oocyte donation versus IVF/ICSI; prematurity and low birthweight were more frequent after oocyte donation versus natural conception (aOR 2.4 and 1.8, respectively)., Conclusions: Patients undergoing oocyte donation represent a group with increased comorbidities and risk factors for adverse obstetric outcomes. Oocyte donation seems to be independently associated with gestational hypertension and PPH. Pregnancies after oocyte donation warrant clinical surveillance with proper screening and, possibly, preventive strategies., (Copyright © 2020 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

Objective: To evaluate semen characteristics and reproductive outcomes after assisted ejaculation methods with fresh in vitro fertilization/intracytoplasmic sperm injection cycles in patients suffering from spinal cord injury (SCI), compared to controls, affected by idiopathic male infertility (non-SCI group)., Methods: SCI patients first underwent penile vibratory stimulation. Men "non-responders" to penile vibratory stimulation underwent electroejaculation. Third, testicular sperm aspiration was proposed., Results: This retrospective monocenter case-control study included 193 couples: 53 couples in SCI group and 140 couples in non-SCI group. Overall, 210 fresh in vitro fertilization/intracytoplasmic sperm injection cycles were performed. Median semen volume of SCI was significantly lower, compared to non-SCI (1.5 mL vs 3.1 mL; P < .01). Median sperm concentration/mL and total sperm count was considerably higher in SCI. Mean sperm progressive motility was significantly lower in SCI (5.0% vs 35.0%; P < .01). Normal fertilization rate was significantly lower in SCI (46.0% vs 71.0%; P < .01). Total fertilization rate was 50.0% and 75%, respectively, in SCI and non-SCI groups. A trend toward higher pregnancy rates per cycle was found in non-SCI (31.4% vs 21.4%), or in the live birth rate, which was 27.1% and 20.0%, respectively. No significant differences were found in pregnancy, miscarriage, and live birth rates per cycle, between the 2 groups., Conclusion: The assisted ejaculation methods in SCI proved to be efficacious and safe to obtain viable sperm for assisted reproductive technologies. Overall, pregnancy and live birth rates were similar to non-SCI patients. Thus, SCI men have the same opportunity to father biological children, compared to men without SCI., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Oxidative stress plays a major role in critical biological processes in human reproduction. However, a reliable and biologically accurate indicator of this condition does not yet exist. On these bases, the aim of this study was to assess and compare the blood and follicular fluid (FF) redox status of 45 infertile subjects (and 45 age-matched controls) undergoing in vitro fertilization (IVF), and explore possible relationships between the assessed redox parameters and IVF outcomes. Reactive Oxygen Species (ROS) production, assessed by flow cytometry analysis in blood leukocytes and granulosa cells, significantly increased (p < 0.05) in infertile patients. Also, oxidative stress markers-ThioBarbituric Acid-Reactive Substances (TBARS) as an index of lipid peroxidation, and Oxygen Radical Absorbance Capacity (ORAC) to account for total antioxidant capacity, both assayed by fluorometric procedures-in blood and FF were significantly (p < 0.001) modified in infertile patients compared to the control group. Moreover, a significant correlation between blood redox markers and FF redox markers was evident. An ORAC/TBARS ratio, defined as the redox index (RI), was obtained in the plasma and FF of the patients and controls. In the patients, the plasma RI was about 3.4-fold (p < 0.0001) lower than the control, and the FF RI was about six-fold (p < 0.0001) lower than the control. Interestingly, both the plasma RI and FF RI results were significantly correlated (p < 0.05) to the considered outcome parameters (metaphase II, fertilization rate, and ongoing pregnancies). Given the reported findings, a strict monitoring of redox parameters in assisted reproductive techniques and infertility management is recommended., Competing Interests: The authors declare no conflict of interest.

Objective: Endometriosis is a frequent indication for in vitro fertilization and embryo transfer (IVF-ET). Its influence on IVF-ET cycles remains controversial. We evaluated the impact of the severity of endometriosis on IVF-ET cycles in young women., Design: Retrospective cohort study., Setting: Academic tertiary referral centre., Sample and Methods: In a retrospective cohort analysis, 164 IVF-ET cycles in 148 women with endometriosis-associated infertility were analyzed. Eighty cycles performed during the same period on 72 consecutive women with tubal infertility were considered as controls. All patients were younger than 35 years old., Main Outcome Measures: Response to controlled ovarian hyperstimulation (COH), number of oocytes retrieved, fertilization, implantation and pregnancy rate (PR)., Results: Clinical PR was lower in the group with endometriosis (all stages) in comparison with the tubal factor group. Higher total gonadotropin requirements, lower response to COH and lower oocyte yield were also found in the endometriosis group. Stage-stratified analysis showed a lower fertilization rate in stage I-II (52.6% stage I-II, 70.5% stage III-IV and 71.9% tubal factor). In stage III-IV endometriosis there was a higher cycle cancellation rate, a reduced response to COH and a lower PR compared with both the stage I-II and the tubal infertility groups (PR 9.7, 25 and 26.1%, respectively)., Conclusions: Stage III-IV was strongly associated with poor IVF outcome. A decreased fertilization rate in stage I-II might be a cause of subfertility in these women, owing to a hostile environment caused by the disease., (© 2011 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2011 Nordic Federation of Societies of Obstetrics and Gynecology.)

Postpartum depression (PPD) is a major depressive disorder that affects women during the perinatal period. Our study aimed to evaluate the onset of psychological effects in spontaneous pregnancies in contrast with pregnancies resulting from in vitro fertilization (IVF). We carried out a prospective cohort study using the Edinburgh Postnatal Depression Scale to evaluate postpartum depression. Patients were divided into 3 different groups based on their conception method: group A included spontaneous pregnancies, group B included pregnancies after homologous IVF, and group C pregnancies after heterologous IVF. The study included 245 patients. In the first year postpartum the incidence of psychological disorders was different exclusively at discharge from hospital (24.8% A vs. 38.7 B vs. 19% C) [P <.05] and one year after childbirth (13.3% A vs. 3.4% B vs. 4.8% C) [P <.05]. The multifactorial analysis showed a significant positive association between psychological distress and advanced maternal age, low parental education, nulliparity, preterm delivery and low fetal weight at birth, multiple pregnancies and multiple births, low pain threshold, and high rate of requesting analgesia intrapartum [P <.05]. Our results suggest a high correlation between PPD and pregnancies resulting from homologous IVF at the time of discharge, whereas there is a higher chance that spontaneous pregnancies develop postpartum depression one year after delivery.

Ovarian stimulation is an important step in the success rate of in vitro fertilization (IVF) allowing multiple follicular growth, several oocytes and consequently more embryos. The combination of GnRH-antagonists (GnRH-ant) and gonadotrophins is now available for clinical use and represent a valid alternative to classical protocol with GnRH agonist. GnRH-antagonists induce a direct block of GnRH receptor with a rapid decrease in LH and FSH, preventing LH surge. Two protocols has been designed for assisted reproduction technology (ART) treatment: multiple-dose protocol and a single-dose. Both protocols are simply, efficacious, started in the late follicular phase and do not have side effects. A review of GnRH-antagonist applications in ART cycles are presented. Smaller doses of gonadotrophins, shorter stimulation period and lower ovarian hyperstimulation syndrome (OHSS) incidence are reported in literature using GnRH-antagonist compared to agonist. Triggering of ovulation, the use in polycystic ovarian syndrome (PCOS) and poor reponders patients are other interesting indication. Regarding to pregnancy rate and potentially adverse effects of drugs on endometrium or implantation needed more data. [Copyright &y& Elsevier]

Objective: To appraise the fertilization rate as a predictive factor for cumulative live birth rate (CLBR).Design: Multicenter retrospective cohort study.Setting: Ten in vitro fertilization clinics, whose data were collected and processed by the assisted reproductive technology (ART) Italian National Registry.Patient(s): 7,968 couples undergoing 9,394 complete intracytoplasmic sperm injection cycles.Intervention(s): None.Main Outcome Measure(s): The primary outcome measure was the CLBR in association with the fertilization rate intervals (<65%-group 1; 65%-80%-group 2; and >80%-group 3). Further data stratification was performed on the basis of maternal age (<34, 35-38, and 39-42 years) and number of retrieved oocytes (5-7, 8-10, and > 10 oocytes).Result(s): The CLBR was progressively higher in relation to the fertilization rate in groups 1, 2, and 3 (20.1%, 34.7%, and 41.3%, respectively). The number of recovered oocytes, embryo number per cycle, and cumulative pregnancy rate followed the same trend. The decrease in CLBR with increasing maternal age was significantly correlated with the fertilization rate and CLBR in all 3 maternal age groups. Multivariate logistic regression analysis showed fertilization rate as a factor independently associated with CLBR.Conclusion(s): The present data indicated a positive association between the fertilization rate and the CLBR, suggesting the predictive clinical relevance of this parameter and its adoption as a key performance indicator.
