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).
1. Follicular Growth: This is the stage in which the egg cell begins to be formed. The primary egg cell is found, as we said before, in what is called the follicle. The formation of the follicle takes about 14 days. A pituitary hormone, FSH (follicle stimulating hormone), comes to the ovaries in the bloodstream.
