Unilateral Ovariectomy Increases Loss of Primordial Follicles and is Associated with Increased Metestrous Concentration of Follicle-Stimulating Hormone in Old Rats1

Role of Follicle Stimulating Hormone in the Survival, Activation and Further Growth of in vitro Cultured Sheep Primordial Follicles

The aim of the present study was to investigate the effect of follicle stimulating hormone (FSH) on survival, activation and growth of ovine primordial follicles using histological studies. Pieces of ovine ovarian cortex were obtained and cultured for 6 days in Minimum Essential Medium supplemented with or without FSH (50 ng/mL). These fragments were then process to be used for histology compar...

The Correlations of Anti-Mullerian Hormone, Follicle-Stimulating Hormone and Antral Follicle Count in Different Age Groups of Infertile Women

Development of human primordial follicles to antral stages in SCID/hpg mice stimulated with follicle stimulating hormone.

In contrast to the many detailed studies of Graafian follicles, the biology of small follicles in the human ovary is poorly understood and the trigger for follicular growth initiation remains unknown. No practical model exists to study preantral follicle growth in the human because of their slow growth rate and lack of an effective culture system. We therefore tested ovarian xenografts as a new...

Follicle stimulating hormone increases spermatogonial stem cell colonization during in vitro co-culture

The complex process of spermatogenesis is regulated by various factors. Studies on spermatogonial stem cells (SCCs) have provided very important tool to improve herd genetic and different field. 0.2 to 0.3 percent of total cells of seminiferous tubules is consist of spermatogonial stem cells. To investigate and biomanipulation of these cells, proliferation and viability rate of cells should be ...
