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).
FSH (follicle stimulating hormone): This is also a hormone that comes from the pituitary gland and stimulates estrogen production in the first half of the cycle. It will stimulate the growth of the follicle that is to be released at ovulation. Levels will become elevated in a woman that is menopausal.
