FSH stimulates the growth and recruitment of immature ovarian follicles in the ovary. In early (small) antral follicles, FSH is the major survival factor that rescues the small antral follicles (2â5 mm in diameter for humans) from apoptosis (programmed death of the somatic cells of the follicle and oocyte).
Follicle stimulating hormone is one of the hormones essential to pubertal development and the function of womenâs ovaries and menâs testes. In women, this hormone stimulates the growth of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation. It also increases oestradiol production.
