Article Synopsis
  • Diminished ovarian reserve (DOR) and primary ovarian insufficiency (POI) significantly contribute to female infertility, with a recent study finding a genetic cause in 29.3% of POI cases.
  • A prospective study of 120 patients with unexplained DOR revealed a 24.2% diagnostic yield using advanced sequencing technology to identify genes related to various biological pathways.
  • Findings indicated that impaired oocyte quality is linked to meiosis/DNA repair genes, and the study supports the need for genetic testing as a routine part of infertility diagnosis and a potential predictor for progression to POI.

Article Synopsis
  • The updated clinical practice guidelines aim to improve the first-line management of infertility in couples by revisiting existing recommendations based on recent research.
  • A systematic review was conducted by expert working groups on five major themes, resulting in 28 PICO-formulated questions addressing both male and female infertility assessments, environmental factors, ovulation induction, and reproductive surgery techniques.
  • Key recommendations include tailored fertility evaluations based on the woman's age, specific tests for both partners, and the dismissal of certain outdated procedures, with an emphasis on evidence-based approaches to optimize infertility treatment.

International guidelines are published to provide standardized information and fertility preservation (FP) care for adults and children. The purpose of the study was to conduct a modified Delphi process for generating FP guidelines for BGD. A steering committee identified 42 potential FP practices for BGD.

Previous studies have demonstrated hysterosalpingography (HSG) in general, and specifically with an oil-soluble contrast medium, directly increases pregnancy rates. Decision modelling was performed to compare fertility management using three HSG diagnostic strategies: (i) water-soluble contrast medium (WSCM)-HSG; (ii) Lipiodol® Ultra Fluid (LUF)-HSG; and (iii) No HSG, for women aged ≤39 years with unexplained infertility. Four reimbursement scenarios were modelled to reflect the various funding arrangements across the regions of the United Kingdom.

Article Synopsis
  • The study evaluated the effectiveness of customized embryo transfers (cET) based on a transcriptomic approach (Win-Test) for patients with repeated implantation failure (RIF), involving 217 participants.
  • The Win-Test assessed the expression of 11 endometrial genes to determine the optimal receptivity window for embryo transfer, revealing that a significant majority (80%) of patients had receptivity timing that differed from the classical protocol.
  • Results showed that pregnancy and live birth rates were significantly higher in the cET group (22.7% and 31.8%) compared to the control group (7.2% and 8.3%), suggesting cET based on Win-Test findings could enhance outcomes for patients with RIF.

Article Synopsis
  • Male infertility is a significant issue for couples globally, but the reasons behind unexplained cases (idiopathic) are still not well understood.
  • Recent research indicates that circulating cell-free nucleic acids might be involved in male infertility and could provide insights into its causes.
  • The review highlights the potential of these nucleic acids as biomarkers for diagnosing male infertility in clinical settings, paving the way for better understanding and treatment options.

Objective: To study fertility after operative hysteroscopy for the management of prolonged trophoblastic retention, and the complications of this procedure.

Study Design: Retrospective cohort in a university hospital.

Article Synopsis
  • Several studies indicate a decline in sperm quality over the decades, prompting a study to evaluate how male factors such as sperm quality and paternal age affect IVF and ICSI outcomes.
  • The study included data from IVF and ICSI treatments at Montpellier University Hospital from 2010 to 2015, analyzing primary outcomes like blastulation and pregnancy rates, alongside secondary outcomes like fertilization and early miscarriage rates.
  • Results showed that severe oligospermia negatively impacted fertilization and blastulation rates, particularly in ICSI, and that paternal age over 51, coupled with maternal age over 37, also reduced pregnancy success rates, suggesting revised fertilization strategies for older couples or those with low sperm quality.

Objectives: To evaluate the fertility of women eligible for surgical multiple myomectomy, but who carefully elected a fertility-sparing uterine artery embolization (UAE).

Methods: Non-comparative open-label trial, on women ≤40 years, presenting with multiple symptomatic fibroids (at least 3, ≥3 cm), immediate pregnancy wish, and no associated infertility factor. Women had a bilateral limited UAE using tris-acryl gelatin microspheres ≥500 μm.

Article Synopsis
  • Ovarian cortex cryopreservation can restore fertility in young women after cancer, but grafts have a limited lifespan due to ischemia.
  • This study compared slow freezing and vitrification techniques for preserving whole ovaries in ewes and assessed the effectiveness of each method.
  • Results showed that while both methods allowed hormonal recovery, vitrification led to significantly better follicle survival rates compared to slow freezing, suggesting it could be a more effective cryopreservation option for future fertility preservation.

Objective: Neuraxial morphine is considered as a "gold standard" for pain relief after cesarean section, however it causes bothersome side effects. Alternative analgesia including nonsteroidal antiinflammatory drugs (NSAID) has been proposed. We aimed to assess the morphine sparing effect of continuous wound infiltration with a local anesthetic, when added to multimodal systemic analgesia including NSAID without subarachnoid morphine.

Background: A multiple pregnancy is now considered to be the most common adverse outcome associated with in vitro fertilization (IVF). As a consequence, the identification of women with the best chances of embryo implantation is a challenge in IVF program, in which the objective is to offer elective single-embryo transfer (eSET) without decreasing the pregnancy rate. To date, a range of hormonal and clinical parameters have been used to optimize eSET but none have significant predictive value.

Introduction: Obtaining an adequate number of high-quality oocytes is a major challenge in controlled ovarian hyperstimulation (COH). To date, a range of hormonal and clinical parameters have been used to optimize COH but none have significant predictive value. This variability could be due to the genetic predispositions of single-nucleotide polymorphisms (SNPs).

Objective: To compare immediate vs delayed medical treatment for first-trimester miscarriage.

Study Design: Randomized open-label trial in a university hospital gynecologic emergency department. Between April 2003 and April 2006, 182 women diagnosed with spontaneous abortion before 14 weeks' gestation were assigned to immediate medical treatment (oral mifepristone, followed 48 hours later by vaginal misoprostol, n = 91) or sequential management (1 week of watchful waiting followed, if necessary, by the above-described medical treatment, n = 91).

This systematic literature review is intended to clarify and evaluate the results obtained by ovarian drilling as surgical treatment for polycystic ovarian syndrome (PCOS). Four databases were consulted (Medline at the National Library of Medicine, USA; Cochrane Library, UK; National Guideline Clearinghouse, USA; and the Health Technology Assessment Database, Sweden) and searched for 'polycystic ovary syndrome' plus 'drilling' in the title or abstract. The assessment criteria used to define the efficacy of the procedure were the rates of ovulation, clinical pregnancy and early miscarriage.

Small human pre-antral follicles can be enzymatically isolated from the surrounding stroma, and are able to survive after 7 days of xenografting. The aim of the present study was to assess the developmental capacity of enzymatically isolated human follicles after long-term xenografting to severe combined immunodeficient (SCID) mice. Ovarian biopsies were obtained from three women 26-29 years of age.

This study was designed to evaluate follicular survival and growth after short-term transplantation of fresh isolated human follicles and ovarian cortical tissue to nude mice. Ovarian biopsies were obtained from nine women undergoing laparoscopy. Twelve nude mice were xenografted with an ovarian cortical fragment in the right ovarian bursa, and a clot containing isolated follicles in the left, for a period of 7 days.
