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

Degeneration rate of preantral follicles in the ovaries of goats [PDF]

, 2002
The degeneration rate of ovarian preantral follicles in goats, and the distribution in the follicular classes (primordial, primary or secondary) was assessed. Ovaries from adult goats were collected at a local slaughterhouse.

Follicular interactions affect the in vitro development of isolated goat preantral follicles

, 2010
SummaryThe aim of this study was to evaluate the influence of the number of follicles per drop (one or three) and antral follicles on in vitro development of isolated goat preantral follicles. Preantral follicles were isolated through microdissection and

A protocol to isolate and qualify purified human preantral follicles in cases of acute leukemia, for future clinical applications

Journal of Ovarian Research, 2018
Background Autotransplantation of cryopreserved ovarian cortex can be associated with a risk of cancer cell reseeding. This issue could be eliminated by grafting isolated preantral follicles. Collagenase NB6 is an enzyme produced under good manufacturing

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.

Zebu (Bos indicus) ovarian preantral follicles : morphological characterization and development of an efficient isolation method [PDF]

, 2002
Preantral follicles are a major source of oocytes, and their utilization as an important tool to store large number of female gametes for future use in reproductive programs has been investigated.

FSH and LH enhance the development of goat preantral follicles cultured in vitro [PDF]

, 2020
This study evaluated the effect of increased follicle stimulating hormone (FSH) concentrations on the expression of mRNA for LH receptors after in vitro culture of goat preantral follicles (≥150 µm) for 18 days.

Real‐Time and High‐Resolution NIR‐II‐L Imaging of Netrin‐1‐Mediated Neurovascular Coupling Driven by Dose‐Dependent Electroacupuncture

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 ...

Salidroside Ameliorates Polycystic Ovary Syndrome in Mice by Regulating the AKT/NF‐κB/NLRP3‐HAS2 Axis

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 ...
