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

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.

Advanced Science, Volume 13, Issue 19, 2 April 2026.Disrupted neurovascular coupling contributes to ovarian dysfunction in polycystic ovary syndrome. Using near‑infrared II long‑wavelength imaging, this study visualizes how electroacupuncture dynamically regulates ovarian blood vessels in vivo. Immediate and cumulative stimulation elicit distinct vascular responses via a Netrin‐1 dependent mechanism ...

Histological and ultrastructural analysis of cryopreserved sheep preantral follicles [PDF]
Animal Reproduction Science, 2006 The aim of this study was to verify the histological and ultrastructural characteristics of sheep preantral follicles after exposure of ovarian tissue to cryopreservation in glycerol (GLY), ethylene glycol (EG), propanediol (PROH) or dimethyl sulfoxide (DMSO) in order to determine the optimum method to store sheep ovarian tissue for later experimental ...

Food Science &Nutrition, Volume 14, Issue 4, April 2026.Salidroside ameliorates PCOS via inhibiting the ROS‐AKT/NF‐κB axis and suppressing NLRP3 inflammasome activation. It disrupts the NLRP3–LAP‐TGFβ1 interaction to block TGF‐β‐SMAD2/3 signaling and consequent ovarian fibrosis. Together with hyaluronan synthase 2 (HAS2) downregulation, these effects alleviate inflammation and hyaluronan overaccumulation ...

Molecular Reproduction and Development, Volume 93, Issue 4, April 2026.ABSTRACT Growth differentiation factor 9 (GDF9) plays a key role in enhancing developmental competence and blastocyst yield during in vitro maturation (IVM). This study investigated whether GDF9 could counteract the harmful effects of lipopolysaccharide (LPS), a gram‐negative bacterial component, on bovine in vitro embryo production, while also ...

Expressions of Kisspeptin System and Ki‐67 in the Reproductive Tissues of Cyclic Bitches
Reproduction in Domestic Animals, Volume 61, Issue 4, April 2026.ABSTRACT Kisspeptin is a peptide that plays a pivotal role in the central regulation of gonadotropins. It is regarded as a key regulator of reproductive processes, including follicular and luteal development and endometrial remodelling. The objective of this study was to investigate the expression of KISS1, its receptor KISS1R and the proliferation ...
