Clinical significance:

FSH levels are used to help determine the reason a man has a low sperm count. FSH levels are also used in the investigation of menstrual irregularities and to aid in the diagnosis of pituitary disorders or diseases involving the ovaries or testes. In children, FSH and LH are used to daignose delayed or precocious (early) puberty.
