Impact of blastocyst biopsy for preimplantation genetic testing on maternal and neonatal outcomes following single frozen embryo transfer cycles.

Background: Up to now, a number of studies have explored the influence of blastocyst biopsy on maternal and neonatal outcomes, and the results have been somewhat inconsistent. Therefore, the aim of this study was to investigate whether blastocyst biopsy is associated with an elevated risk of hypertensive disorders of pregnancy (HDP) and other adverse perinatal outcomes during frozen embryo transfer (FET) cycles in singleton live births resulting from intracytoplasmic sperm injection (ICSI) in women aged ≤ 35 years.

Methods: A total of 1,008 women were involved in this study from January 2020 to June 2022, who underwent ICSI cycles and received single FET, leading to the birth of a live singleton newborn.

Bariatric Surgery as a Molecular Modulator: The Role of FSHR Polymorphisms in Enhancing eNOS Expression and Reproductive Hormone Dynamics in Women with Severe Obesity.

Background/objectives: Severe obesity (BMI > 40 kg/m) has a severe influence on vascular health and reproduction. This study looks at how bariatric surgery affects endothelial nitric oxide synthase (eNOS) expression and reproductive hormone regulation across different follicle-stimulating hormone receptor (FSHR) polymorphism groups in women with extreme obesity.

Methods: Twenty-nine women with extreme obesity had bariatric surgery.

Nitrate-Nitrite-Nitric Oxide Pathway, Oxidative Stress, and Fertility Outcomes in Morbidly Obese Women Following Bariatric Surgery: A Systematic Review.

Obesity reduces nitric oxide (NO) production due to endothelial nitric oxide synthase (eNOS) dysfunction, resulting in oxidative stress, mitochondrial dysfunction, and chronic inflammation. These factors have a negative impact on reproductive health, including oocyte quality, endometrial receptivity, and embryo implantation. When oxidative stress affects eNOS function, the nitrate-nitrite-nitric oxide (NO-NO-NO) pathway provides an alternate route for NO production.

Detrimental effects of cadmium on male infertility: A review.

Infertility has become a serious health and socio-economic-psychological problem globally. The harmful role of trace metals in male infertility is recognized but still not sufficiently explained. Herein, a comprehensive review was conducted to elucidate the detrimental role of cadmium (Cd) on male infertility, particularly on infertility with unknown (idiopathic) causes.

Flexible progestin-primed ovarian stimulation versus a GnRH antagonist protocol in predicted suboptimal responders undergoing freeze-all cycles: a randomized non-inferiority trial.

Study Question: Are live birth rates (LBRs) per woman following flexible progestin-primed ovarian stimulation (fPPOS) treatment non-inferior to LBRs per woman following the conventional GnRH-antagonist protocol in expected suboptimal responders undergoing freeze-all cycles in assisted reproduction treatment?

Summary Answer: In women expected to have a suboptimal response, the 12-month likelihood of live birth with the fPPOS treatment did not achieve the non-inferiority criteria when compared to the standard GnRH antagonist protocol for IVF/ICSI treatment with a freeze-all strategy.

What Is Known Already: The standard PPOS protocol is effective for ovarian stimulation, where medroxyprogesterone acetate (MPA) is conventionally administered in the early follicular phase for ovulatory suppression. Recent retrospective cohort studies on donor cycles have shown the potential to prevent premature ovulation and maintain oocyte yields by delaying the administration of MPA until the midcycle (referred to as fPPOS), similar to GnRH antagonist injections.

Epigenomic Landscape of Human Cumulus Cells in Premature Ovarian Insufficiency Using Single-Base Resolution Methylome and Hydroxymethylome.

Premature ovarian insufficiency (POI) has recently been reported to be linked with epigenetic changes. Previous studies have focused on the regulation of individual genes associated with ovarian function through single-gene epigenetic variations; however, there is a deficiency in the comprehensive comprehension of the epigenetic profile for POI. Therefore, we conducted a multi-omics study integrating methylation, hydroxymethylation and transcriptome sequencing analyses in cumulus cells from women with POI and their matched controls.
