Preconception 1-hour blood glucose as an early indicator of gestational diabetes mellitus risk in PMOS/PCOS women undergoing IVF treatment: a multi-centre cohort study

Aug 9, 2026

The study investigates whether preconception 1-hour plasma glucose levels during an oral glucose tolerance test (OGTT) are more predictive of gestational diabetes mellitus (GDM) compared to fasting or 2-hour glucose levels in women with PMOS/PCOS undergoing IVF treatment. The findings indicate that 1-hour glucose levels show a stronger and more consistent association with GDM risk, particularly in normal-weight and obese women, suggesting its potential value in preconception metabolic assessments for this population.

Mastering reproduction across the globe: the growing and sustained impact of master's degree programs in reproductive science and medicine

Aug 4, 2026

This study investigates the sustained impact of master's degree programs in reproductive science and medicine on addressing the global demand for expertise in this field. The authors provide quantitative evidence that these programs are effectively training a well-prepared workforce, with a notable increase in program offerings and diverse career outcomes for graduates. The findings highlight the importance of establishing a formal consortium to standardize data collection and track alumni success across these programs.

Mitochondria-targeted therapeutic strategies in assisted reproduction: challenges and potential solutions

Aug 3, 2026

The authors investigate the role of mitochondria in oocyte competence and early embryonic development, particularly how mitochondrial dysfunction contributes to reproductive challenges such as diminished ovarian reserve and impaired embryo development. They explore various mitochondria-targeted therapeutic strategies and highlight the need for more precise, well-defined interventions, as current clinical outcomes are inconsistent due to limitations in study design and therapeutic timing. The paper emphasizes the importance of rigorous safety evaluations and the development of standardized approaches to enhance the efficacy of these therapies in assisted reproduction.

Ambient temperature reduces oocyte yield in assisted reproductive technology via a partially sex hormone-mediated pathway

Aug 2, 2026

The study investigates whether higher ambient temperatures before oocyte retrieval negatively affect oocyte yield in women undergoing their first IVF or ICSI cycle. The findings indicate that each 1°C increase in apparent temperature is associated with a significant decrease in total and mature oocytes retrieved, with luteinizing hormone (LH) partially mediating this effect, while compensatory increases in follicle-stimulating hormone (FSH) and estradiol (E2) were also observed. These results highlight ambient temperature as a modifiable environmental risk factor for oocyte yield in assisted reproductive technology.

Increased risk of congenital anomalies after fertility treatment is partially mediated by multiple birth: a population-based cohort study

Jul 31, 2026

The study investigates the extent to which multiple births mediate the association between fertility treatment and the risk of congenital anomalies. The findings indicate that while multiple births account for some of the increased risk, the majority of the excess risk of congenital anomalies associated with fertility treatment is independent of multiple births, suggesting that other factors related to infertility and treatment may also contribute significantly.

Body fat percentage in relation to semen characteristics, testicular volume, and reproductive hormones: a cross-sectional study

Jul 29, 2026

This study investigates the relationship between body fat percentage and semen characteristics, testicular volume, and reproductive hormone levels in young men. The authors found that higher body fat percentages were linked to poorer semen quality and altered hormone levels, while no significant association with testicular volume was observed. Notably, the impact of body fat percentage on semen characteristics was stronger than that of BMI and waist-to-height ratio, even among men classified as normal weight by BMI.

LRPPRC deficiency impairs trophoblast function through disrupted phosphatidylinositol metabolism in recurrent pregnancy loss

Jul 28, 2026

The authors investigate whether leucine-rich pentatricopeptide repeat-containing protein (LRPPRC) is involved in recurrent pregnancy loss (RPL) and the underlying mechanisms. They find that LRPPRC deficiency disrupts phosphatidylinositol metabolism, leading to impaired trophoblast viability, increased apoptosis, and oxidative stress, with low preconception serum levels of specific phosphatidylinositol species predicting subsequent miscarriage in women with RPL. The study suggests that phosphatidylinositol could serve as a mechanistic biomarker and therapeutic target in RPL.

Associations of anti-Müllerian hormone with primordial follicle density and in vitro maturation outcomes in girls with transfusion-dependent thalassemia undergoing fertility preservation

Jul 28, 2026

The authors aimed to investigate the relationship between serum anti-Müllerian hormone (AMH) levels, primordial follicle density (PFD), and in vitro maturation (IVM) outcomes in pediatric and adolescent girls with transfusion-dependent thalassemia undergoing fertility preservation. They found that while AMH levels were not correlated with PFD, higher AMH was positively associated with increased oocyte yield and improved maturation rates during IVM. The study highlights the need for cautious interpretation of AMH in fertility preservation counseling, as it does not serve as a reliable surrogate for the primordial follicle pool.

Microbiome and chronic pelvic pain in women: a mini-review

Jul 24, 2026

This mini-review investigates the role of the human microbiome in chronic pelvic pain (CPP) in women, exploring how dysbiosis in various microbial ecosystems may contribute to the pathophysiology of overlapping disorders such as endometriosis and interstitial cystitis. The authors synthesize evidence linking microbial alterations to immune dysregulation and chronic pain mechanisms, while also discussing potential microbiome-targeted interventions and the need for future research to establish causal relationships and therapeutic strategies.

Can AI speak endo? A multi-platform evaluation of large language models against ESHRE endometriosis guidelines

Jul 21, 2026

The authors aimed to evaluate the performance of three widely accessible large language models in accurately, consistently, and reliably answering clinically relevant questions based on the 2022 ESHRE guidelines for endometriosis. They found that while one model (Model A) achieved the highest accuracy and another (Model C) demonstrated superior consistency, all models exhibited suboptimal reliability under free-tier access, highlighting the need for expert oversight in clinical applications. The study provides a benchmark for assessing AI tools in reproductive medicine and suggests that model performance may vary significantly based on access tier.
