Effect of Preimplantation Genetic Testing for Aneuploidy on Live Birth Rate in Young Women With Recurrent Implantation Failure: A Secondary Analysis of a Multicentre Randomised Trial.

Objective: To investigate the benefit of preimplantation genetic testing for aneuploidy (PGT-A) in recurrent implantation failure (RIF).

Design: Secondary analysis of a multicentre, randomised, double-blind, placebo-controlled clinical trial.

Setting: Eight academic fertility centres in China, 2018-2020.

Mechanism of Marinobufagenin-Induced Hyperpermeability of Human Brain Microvascular Endothelial Cell Monolayer: A Potential Pathogenesis of Seizure in Preeclampsia.

Preeclampsia (preE) is a hypertensive disorder in pregnancies. It is the third leading cause of mortality among pregnant women and fetuses worldwide, and there is much we have yet to learn about its pathophysiology. One complication includes cerebral edema, which causes a breach of the blood-brain barrier (BBB).

Racial Disparities in Parturient Urine Drug Screening at a Texas Level IV Maternal Care Centre: A Single-Centre Retrospective Study.

Objectives: We hypothesized that Black or African American (hereby referred to as Black) and Hispanic patients would have higher rates of urine drug screening (UDS) during pregnancy compared with White or Caucasian (herby referred to as White) patients at our hospital.

Methods: Patients who delivered at our hospital between 1 December 2020 and 31 May 2021 and between 1 December 2022 and 31 May 2023 and who were Black, Hispanic, or White were included in the final analysis. We performed separate bivariate analyses comparing White patients to either Black patients or Hispanic patients.

In-vitro fertilization experience with follitropin-delta in poor responders identified by POSEIDON Classification.

Background: Controlled ovarian stimulation during in-vitro fertilization (IVF) is personalized based on anticipated hyper, normal, poor response. With respect to poor responders, who are often treated using higher gonadotropin dosing and combination of urinary and recombinant gonadotropins (rFSH) with marginal benefit, we report our experience with a newer, more potent rFSH (Follitropin-δ) undergoing IVF.

Methods: Retrospective analysis of all IVF cycles in which follitropin-δ was used alone or combined with urinary gonadotropins over a 3-year period.

Pravastatin Protects Cytotrophoblasts from Hyperglycemia-Induced Preeclampsia Phenotype.

Unlabelled: There are no effective therapies to prevent preeclampsia (PE). Pravastatin shows promise by attenuating processes associated with PE such as decreased cytotrophoblast (CTB) migration, aberrant angiogenesis, and increased oxidative stress. This study assesses the effects of pravastatin on hyperglycemia-induced CTB dysfunction.

What's Now and What's Next for Surgical Endometriosis Management in the Infertile Patient? An Evidence-Based Review for the General OB/GYN.

Endometriosis is a significant contributor to female infertility, and its complex nature and varied phenotypes lead to questions regarding the value of surgical management. In this manuscript, we summarize current evidence and recommendations regarding surgical treatment for infertility in peritoneal disease, endometriomas, adenomyosis, and deep endometriosis, and highlight recent evidence regarding perinatal outcomes in women with endometriosis. Our purpose is to provide a concise "user's guide" for decisions regarding the surgical management of endometriosis in patients with infertility and generate awareness of recent perinatal outcome data.

Trophectoderm grade is associated with the risk of placenta previa in frozen-thawed single-blastocyst transfer cycles.

Study Question: Do obstetric and perinatal complications vary according to different blastocyst developmental parameters after frozen-thawed single-blastocyst transfer (SBT) cycles?

Summary Answer: Pregnancies following the transfer of a blastocyst with a grade C trophectoderm (TE) were associated with an increased risk of placenta previa compared to those with a blastocyst of grade A TE.

What Is Known Already: Existing studies investigating the effect of blastocyst morphology grades on birth outcomes have mostly focused on fetal growth and have produced conflicting results, while the risk of obstetric complications has rarely been reported. Additionally, growing evidence has suggested that the appearance of TE cells could serve as the most important parameter for predicting implantation and live birth.

Surgical management of an ectopic pregnancy in the setting of an unexpected Müllerian anomaly: intraoperative and postoperative implications.

Objective: To describe the intraoperative and postoperative implications arising from the unexpected diagnosis of a Müllerian anomaly during the surgical management of an ectopic pregnancy.

Design: Video article.

Setting: Academic center.

Effectiveness of Manual Hysteroscopic Tissue Removal Device for Intrauterine Polyps in Infertile Women in Both Operating and Office Settings.

: Mechanical hysteroscopic tissue removal (mHTR) systems are widely used for removing intrauterine pathology. Given the startup and procedural costs for electrically powered mechanical units, disposable manual mHTR systems have been developed. : With little published, we describe its effectiveness for hysteroscopic intrauterine polypectomy.

Effects of SARS-COV-2 infection during the frozen-thawed embryo transfer cycle on embryo implantation and pregnancy outcomes.

Study Question: Does severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during the frozen-thawed embryo transfer (FET) cycle affect embryo implantation and pregnancy rates?

Summary Answer: There is no evidence that SARS-CoV-2 infection of women during the FET cycle negatively affects embryo implantation and pregnancy rates.

What Is Known Already: Coronavirus disease 2019 (COVID-19), as a multi-systemic disease, poses a threat to reproductive health. However, the effects of SARS-CoV-2 infection on embryo implantation and pregnancy following fertility treatments, particularly FET, remain largely unknown.

Psychosocial outcomes of children born via embryo donation.

Study Question: What are parents' perceptions of their relationships with and the psychosocial adjustments of their children who are born via embryo donation?

Summary Answer: Families created through embryo donation have well-adjusted parent-child relationships and reassuring child psychosocial outcomes.

What Is Known Already: Embryo donation is an effective and growing form of third-party reproduction, but there is limited research in this field. Prior studies suggest that families created through gamete donation function well regarding parent-child relationship quality and child behavioral and socioemotional adjustment.

Total and bioavailable 25-hydroxyvitamin D is not associated with improved sexual dysfunction following vitamin D supplementation in women with polycystic ovarian syndrome: a pilot study.

Background: Vitamin D (Vit D) deficiency has been linked to symptoms of polycystic ovary syndrome (PCOS), yet little is known about Vit D supplementation as a treatment for sexual dysfunction (SDy) in women with PCOS.

Aim: To explore the implications of serum total 25-hydroxyvitamin D (25[OH]D) and bioavailable 25[OH]D (bio-25[OH]D) status and replacement on women with PCOS and SDy.

Methods: Reproductive-age women with PCOS who were not desiring fertility were eligible provided that they also had SDy, as assessed by the Female Sexual Function Index (FSFI), and were without severe depression, as evaluated by the Beck Depression Inventory II (BDI-II).

Anti-Müllerian hormone levels are associated with skeletal maturity in adolescent girls in the Fels Longitudinal Study.

The role of anti-Müllerian hormone (AMH), a potential marker of the hypothalamic-pituitary-ovarian axis, is not well established in adolescent females. Most studies use secondary sexual characteristics or chronological age as predictors for AMH. Skeletal maturity, an indicator of bone development, has not been examined to predict AMH.

Benefits of Blastocyst Transfer With at Least Three Good-Quality Cleavage-stage Embryos in Women of Advanced Maternal Age: A Retrospective Analysis.

Objectives: Limited studies on the benefits of blastocyst transfer in advanced maternal age (AMA) (≥40 years) have been reported. Our objective was to find whether blastocyst-stage embryo transfer improves pregnancy and live birth rates in women ≥40 years who have 3 or more good-quality cleavage-stage embryos.

Methods: All fresh in vitro fertilization-intracytoplasmic sperm injection cycles performed from January 2020 to December 2021 in AMA women that progressed to transfer were considered for analysis.
