Pioglitazone suppresses excessive follicular development in murine preantral follicles. [PDF]

J Ovarian Res, 2019
Polycystic ovary syndrome (PCOS) is an endocrine disease that is common in women in their reproductive period. Patients with this disease suffer from anovulation and hyperandrogenism. Ovulation induction with exogenous gonadotropin often causes ovarian hyperstimulation syndrome because many small antral follicles pause in their growth.

Mouse serum facilitates the expansion of the follicular cavity regardless of the estrous cycle phase [PDF]

Journal of Ovarian Research
Objective In investigating the effect of alcohol intake on the in vitro development of preantral follicles, physiological differences across estrous cycle phases in mice probably affect the results; therefore, it is necessary to determine whether serum ...

Cryopreservation and In Vitro Culture of Isolated Porcine Ovarian Follicles [PDF]

Veterinary Sciences
Cryopreservation of preantral follicles (PAFs) is a promising tool for gene conservation and fertility preservation. However, standardized protocols for the cryopreservation and in vitro culture of isolated follicles—particularly in pigs—are still ...

Eugenol Improves Follicular Survival and Development During in vitro Culture of Goat Ovarian Tissue

Frontiers in Veterinary Science, 2022
This study evaluated the effects of different concentrations (10, 20, or 40 μM) of eugenol (EUG 10, EUG 20, or EUG 40), ascorbic acid (50 μg/mL; AA) or anethole (300 μg/mL; ANE 300) on the in-vitro survival and development of goat preantral follicles and

Characterization of preantral follicle clustering and neighborhood patterns in the equine ovary

PLoS ONE, 2022
Understanding the transition from quiescent primordial follicles to activated primary follicles is vital for characterizing ovarian folliculogenesis and improving assisted reproductive techniques.

Review: Roles of follicle-stimulating hormone in preantral folliculogenesis of domestic animals: what can we learn from model species and where do we go from here?

Animal, 2023
The pituitary gonadotropin FSH is a glycoprotein critical for the development of ovarian follicles. Upon binding to its G protein-coupled membrane receptor located on the granulosa cells of ovarian follicles, FSH elicits a cascade of downstream ...

-growth and Gene Expression of Porcine Preantral Follicles Retrieved by Different Protocols [PDF]

Asian-Australasian Journal of Animal Sciences, 2012
This study was conducted to determine how the isolation method of the porcine preantral follicles influenced the following follicular growth in vitro. Mechanical and enzymatical isolations were used for retrieving the follicles from prepubertal porcine ...

Ultrastructure and viability of isolated bovine preantral follicles [PDF]

Human Reproduction Update, 1998
Techniques for the isolation of ovarian follicles and maturation of oocytes in vitro have enormous reproductive potential. Preservation of normal tissue function is vital. This study emphasizes the ultrastructure and viability of mechanically isolated bovine small (diameter 40-100 microm) preantral and large (140-450 microm) preantral/early antral ...
