Clinical Significance
Human LH and FSH levels are commonly determined in investigations of menstrual, fertility, and pubertal developmental disorders such as premature ovarian failure, menopause, ovulatory disorders and pituitary failure. The ratio of LH/FSH has been used to assist in the diagnosis of polycystic ovary disease.
Low levels of LH and FSH may indicate pituitary failure while elevated LH and FSH levels along with decreased levels of gonadal steroids may indicate gonadal failure (menopause, ovariectomy, premature ovarian syndrome, Turner&rsquo s Syndrome). Low gonadotropin levels are usually observed in females taking oral steroid-based contraceptives. In the male, elevated FSH and LH with low levels of gonadal steroids may indicate testicular failure or anorchia. In Klinefelter&rsquo s syndrome FSH may be elevated due to Sertoli cell failure.
