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

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.

Advanced Science, Volume 12, Issue 29, August 7, 2025.Iron overload in ovarian endometriosis (OE) disrupts follicular function and contributes to infertility. This study maps iron‐induced cellular changes using single‐cell and spatial transcriptomics, revealing senescence phenotypes in OE patients and mouse models. Similar patterns are observed in aging ovaries, highlighting iron metabolism as a potential

Development of Mouse Preantral Follicle after In Vitro Culture in A Medium Containing Melatonin [PDF]
Cell Journal, 2015 Objective: Improvements in cancer treatment have allowed more young women to survive. However, many cancer patients suffer from ovarian failure. Cryopreservation is one of the solutions for fertility restoration in these patients. The cryopreservation of
