The Regulation of Apoptosis in Preantral Ovarian Follicles
Neurosignals, 2000 Less than 1% of ovarian follicles ever mature to ovulation. The remainder undergo atretic degeneration via apoptosis during development. Though the regulation of antral and preovulatory survival has been studied for many years, very little is known about the regulation of survival and development of preantral follicles.

Preantral follicle population, spatial distribution, and ovarian tissue autotransplantation in mares [PDF]
, 2022 Folliculogenesis is a complex and dynamic process by which follicles grow and develop with the goal of releasing a fertilizable oocyte upon ovulation. At birth, most females have a large pool of follicles; however, this pool is naturally depleted over ...

Ovarian Matrisome Dynamics and αvβ3‐Mediated Regulation in Early Follicular Development
Advanced Science, Volume 13, Issue 29, 22 May 2026.The matrisome undergoes dynamic remodeling during early follicular development. Integrin αvβ3 mediates matrisome signals, regulating primordial follicle activation/atresia and secondary follicle growth via Hippo/mTOR pathways, with conserved roles in human ovaries, offering therapeutic targets for ovarian disorders.

Luteinizing hormone receptor knockout mouse: What has it taught us?
Andrology, Volume 14, Issue 4, Page 1017-1028, May 2026.Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...

Journal of Obstetrics and Gynaecology Research, Volume 52, Issue 5, May 2026.ABSTRACT Aim We had defined the anti‐Müllerian hormone (AMH) cut‐off value level 2 aligned with the Rotterdam/International Evidence‐based Guideline (IEBG) for the Assessment and Management of polycystic ovary syndrome (PCOS) 2023 criteria. In this study, we evaluated the utility of AMH cut‐off value level 2 in patients who could not be diagnosed under
