Leptin–cholesterol crosstalk in pregnancy: Mechanistic implications for placental function and cardiometabolic programming

Experimental Physiology, EarlyView.
Abstract Pregnancy requires the coordinated maternal reorganization of lipid and endocrine pathways to sustain fetal growth and anticipate neonatal nutrition. Leptin, produced by adipose tissue and the placenta, acts as an integrative signal linking maternal energy status with trophoblast function and vascular adaptation, while cholesterol provides ...

Unique morphological characteristics in the ovary of cotton rat (Sigmodon hispidus)

The Journal of Reproduction and Development, 2020
Cotton rats (Sigmodon hispidus, CRs) are commonly used as animal models in biomedical research. However, the reproductive characteristics and ovarian development in the CRs has not been widely investigated.

Anti‐Müllerian Hormone and Metabolic–Hormonal Profiles in Women With and Without Polycystic Ovary Syndrome: A Population‐Based Study

Endocrinology, Diabetes &Metabolism, Volume 9, Issue 5, September 2026.
In this population‐based study of 883 women, AMH declined less with age in women with PCOS than in healthy women. Higher AMH may protect older healthy women from T2DM but indicates elevated metabolic risk in younger women with PCOS, supporting its role as a life‐course biomarker for metabolic risk stratification.

Folliculogenesis and Abnormalities

Journal of Gynecology Research Reviews & Reports
Research on oocytes and their associated follicles has advanced significantly over the past two decades, shedding light on the fragility of the processes governing their active life. The ovarian follicles and the germ cells within them are crucial to understand conception, growth, and survival mechanisms.

Graded Levels of Dietary Valine in Protein‐Restricted Diets: Effects on Reproductive Performance and Tissue Morphology in Laying Japanese Quail

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Dietary supplementation of 0.95% valine in protein‐restricted diets optimizes reproductive performance, egg quality, and ovarian follicular development in laying Japanese quail. Higher levels do not provide additional benefits and may increase hepatic metabolic demand, highlighting the importance of precise amino acid formulation in low‐protein feeding

Mapping Steroidogenic Perturbations Under Endocrine Disruptor Mixtures Across Demographic Subgroups: Structural and Metabolomic Insights

Advanced Science, Volume 13, Issue 46, 17 August 2026.
Population‐scale EDC–hormone association mapping among 4255 participants across demographic subgroups identifies phthalate metabolites as the most consistent signals associated with lower testosterone‐related markers in males. Integrative mechanistic validation prioritizes MCPP as a key phthalate metabolite linked to CYP17A1‐centered disruption of ...

Effects of Naringenin (NG) as an Anti- Proliferative and Anti-Apoptotic Factor on ER Alpha and ER Beta in PCOS

Advanced Biomedical Research
Background: Polycystic ovary syndrome (PCOS) is the most prevalent endocrine disorder among women of reproductive age, characterized by elevated androgen levels, chronic inflammation, and oxidative stress.

Study on the Effects and Mechanisms of Sea Buckthorn Fruit Pulp in Improving Polycystic Ovary Syndrome

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Sea buckthorn pulp improves metabolic and reproductive dysfunction in a letrozole‐induced PCOS mouse model and is associated with modulation of the PI3K/AKT/mTOR signaling pathway. ABSTRACT Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder characterized by ovarian dysfunction, hyperandrogenism, and insulin resistance.

Luteal phase stimulation versus follicular phase stimulation in poor ovarian responders: A systematic review and a meta‐analysis

International Journal of Gynecology &Obstetrics, Volume 174, Issue 2, Page 608-620, August 2026.
Abstract Background Poor ovarian response (POR) complicates a substantial proportion of in vitro fertilization (IVF) cycles, frequently causing cycle cancellation and suboptimal reproductive outcomes. Conventional follicular‐phase ovarian stimulation (FPOS) protocols often yield limited results, prompting the evaluation of alternative strategies such ...
