The correct answer is: egg growth.
Follicle stimulating hormone (FSH) is gonadotrophic hormone produced by the pituitary gland with the function to regulate the growth and development of both the ovaries and testes.
FSH stimulates the growth and maturation of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation and increases oestradiol production.
The secretion of FSH is controlled by gonadotropin-releasing hormone (GnRH) released from hypothalamus.
