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.

Unraveling ovarian histology: The key morphological aspects that spur the development of the Fossa ovarii in equine

The Anatomical Record, EarlyView.
Abstract The equine ovary exhibits unique structural and developmental features that distinguish it from those of other domestic species, including the presence of an ovulation fossa and an inversion of cortical and medullary layers. This study aimed to investigate the morphostructural development of the equine fetal ovary, with particular emphasis on ...

Abnormalities of early folliculogenesis and serum anti-Müllerian hormone in chinese patients with polycystic ovary syndrome

Journal of Ovarian Research, 2021
Purpose To investigate abnormalities of early folliculogenesis and Anti-Müllerian hormone (AMH) concentrations in polycystic ovary syndrome (PCOS) patients, and to analyze the association between AMH and early-stage follicle densities (FD).

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 ...

A New Diagnostic Strategy for Polycystic Ovary Syndrome Combining Japanese and International Diagnostic Criteria Using Anti‐Müllerian Hormone

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

Serine threonine kinase receptor associated protein regulates early follicle development in the mouse ovary. [PDF]

, 2017
The molecular mechanisms involved in regulating the development of small, gonadotrophin-independent follicles are poorly understood; however, many studies have highlighted an essential role for TGFB ligands.

Identification of A p300–SP1–BRD4 Transcriptional Axis as a Key Driver of AR Hyperactivation in Polycystic Ovarian Syndrome

Advanced Science, Volume 13, Issue 23, 23 April 2026.
This study reveals a pivotal epigenetic regulatory role for the histone acetyltransferase p300, demonstrating that its acetylation of histone 3 at lysine 18 and 27 (H3K18ac and H3K27ac), alongside the formation of the p300/BRD4/SP1 complex, drives AR activation and ovarian fibrosis in PCOS.
