Preserving Fertility in Young Women: Triple‐Step Strategy for Managing Giant Endometriomas With Minimal AMH Decline—A Case Report

Case Reports in Obstetrics and Gynecology, Volume 2026, Issue 1, 2026.
Endometriomas are a frequent cause of infertility in reproductive‐aged women, often requiring surgery. However, cystectomy for large endometriomas may reduce ovarian reserve, as indicated by decreased anti‐Müllerian hormone (AMH) levels. This case report presents a triple‐step approach to managing a 20‐year‐old woman with bilateral endometriomas and ...

Development of antral follicles after xenografting of isolated small human preantral follicles

Reproductive BioMedicine Online, 2008
Small human pre-antral follicles can be enzymatically isolated from the surrounding stroma, and are able to survive after 7 days of xenografting. The aim of the present study was to assess the developmental capacity of enzymatically isolated human follicles after long-term xenografting to severe combined immunodeficient (SCID) mice.

Cytomolecular and In Vitro Toxicity Studies on Bisphenol A Effect on Ovine Granulosa Cells

Veterinary Medicine International, Volume 2026, Issue 1, 2026.
Bisphenol A (BPA), an organic environment chemical, has extensive presence in consumer goods and food/feed items. The present study aimed to explore how BPA influenced the viability, proliferation, apoptosis, and steroidogenic activity of ovine ovarian granulosa cells (GCs).

Canine preantral follicles cultured with various concentrations of follicle-stimulating hormone (FSH)

Theriogenology, 2010
The objective was to evaluate the effects of various concentrations of exogenous FSH during in vitro culture of isolated canine preantral follicles. Preantral secondary follicles (>200 microm) were isolated by microdissection and cultured for 18 d in supplemented alpha-Minimum Essential Medium (alpha-MEM).

The art of oocyte meiotic arrest regulation

Reproductive Biology and Endocrinology, 2019
A central dogma of mammalian reproductive biology is that the size of the primordial follicle pool represents reproductive capacity in females. The assembly of the primordial follicle starts after the primordial germ cells (PGCs)-derived oocyte releases ...

Vascular supply as a discriminating factor for pig preantral follicle selection

, 2009
This research analyses how somatic and vascular compartments change during preantral follicle growth. To address this aim, theca-granulosa (somatic) proliferation indexes (PIs), proportion of proliferating endothelial cells (PE), vascular area (VA) and ...
