Clinical Significance

Follicle stimulating hormone (FSH) and LH control growth and reproductive activities of gonadal tissues. FSH promotes follicular development in the ovary and gametogenesis in the testis. The gonadotroph cells of the anterior pituitary secrete both FSH and LH in response to gonadotropin releasing hormone from the hypothalamus. Release of FSH is controlled by a negative feedback by the gonads.

 

FSH in mature females acts to stimulate development of ovarian follicles. Circulating levels of FSH vary throughout the menstrual cycle.

 

FSH levels increase significantly in menopause due to decreased feedback inhibition. Increased values are seen in primary testicular or ovarian failure, chromosomal disorders and alcoholism. Decreased values are seen in hypopituitarism, delayed puberty, anorexia nervosa, post pregnancy, and with oral contraceptive use.
