The Impact of Melatonin Supplementation on Various Aspects of Polycystic Ovary Syndrome: A Systematic Review and Meta‐Analysis

Health Science Reports, Volume 8, Issue 10, October 2025.
ABSTRACT Background and Aims Polycystic ovary syndrome (PCOS) is a prevalent gynecological condition affecting women of reproductive age, with implications for multiple aspects of women's health. Recent research indicates that melatonin (MLT) may enhance several dimensions of this syndrome via various mechanisms. Consequently, this study was undertaken

Impact of Neutral Sphingomyelinase Inhibition on Small Extracellular Vesicle Production by Mural Granulosa Cells and In Vitro Folliculogenesis in Mice

Molecular Reproduction and Development, Volume 92, Issue 10, October 2025.
ABSTRACT Small extracellular vesicles (sEVs) function as critical regulators of ovarian follicular development. Although several pathways, including one involving neutral sphingomyelinase (nSMase), contribute to sEV production, the specific pathway active in ovarian follicles has not been clearly identified.

Compound Heterozygous Variants in ZSWIM7 Gene Linked to Infertility and Its Role in Gonadal Development

American Journal of Medical Genetics Part A, Volume 197, Issue 9, September 2025.
ABSTRACT This study aims to elucidate the role of the ZSWIM7 gene in the etiology of infertility, focusing on its potential association with premature ovarian insufficiency and azoospermia. We investigated an 18‐year‐old female patient who presented with primary amenorrhea, hypoplasia of the uterus and ovaries, Tanner stage II breast and pubic hair ...

Anti‐Müllerian Hormone Levels Are Associated With Skeletal Maturity in Adolescent Girls: A Longitudinal Study

Health Science Reports, Volume 8, Issue 9, September 2025.
ABSTRACT Background and Aims The role of anti‐Müllerian hormone (AMH), a potential marker of the hypothalamic–pituitary–ovarian axis, is not well established in adolescent females. Typical epidemiologic studies use secondary sexual characteristics or chronological age as predictors for AMH.

GADD45A is Essential for Granulosa Cells Differentiation and Ovarian Reserve in Human and Mice

Journal of Cellular and Molecular Medicine, Volume 29, Issue 17, September 2025.
ABSTRACT Diminished ovarian reserve (DOR) poses significant challenges in reproductive health, with emerging evidence implicating DNA damage repair pathways. While GADD45A is a critical regulator of DNA repair, cell cycle and apoptosis, its role in DOR pathogenesis remains unexplored. We employed transcriptome sequencing, qPCR and Western Blot analyses

Semaphorin 3E‐Plexin‐D1 Pathway Downstream of the Luteinizing Hormone Surge Regulates Ovulation, Granulosa Cell Luteinization, and Ovarian Angiogenesis in Mice

Advanced Science, Volume 12, Issue 29, August 7, 2025.
The Semaphorin 3E (Sema3E)‐Plexin‐D1 pathway mediated by C/EBPα and C/EBPβ downstream of the luteinizing hormone (LH) surge plays important roles in the mouse preovulatory ovary. Timely activation and suppression of this pathway during the preovulatory stage are crucial for ovulation, corpus luteum formation, and proper angiogenesis.
