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.

The Role of Anethole in Reproductive Physiology and In Vitro Biotechnologies—A Review

Reproduction in Domestic Animals, Volume 61, Issue 1, January 2026.
ABSTRACT In vitro reproductive biotechnologies show promise for fertility preservation but still face challenges, including oxidative stress from high oxygen tension, which impairs cell viability and development. Antioxidants have been widely explored to attenuate oxidative stress during culture.

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).

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 ...

Effects of lowered temperatures and media on short-term preservation of zebu (Bos indicus) preantral ovarian follicles [PDF]

, 2004
The maintenance of follicle quality during the transportation of ovaries is essential for the successful cryopreservation and in vitro development of preantral follicles. The objective of this study was to evaluate the effect of cooling ovarian tissue on

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).
