Clinical Significance
In vitro diagnostic test for the quantitative measurement of lutenizing hormone in human plasma, used in the diagnosis and treatment of gonadal dysfunction.  Elevated LH levels may indicate primary ovarian or testicular failure.  In females menopause and polycystic ocary disease can also cause elevated levels.  Low LH levels may indicate either pituitary deficiency or suppression of hypergonadism in either sex.  LH and LH/FSH ratios are useful in diagnosing and treating infertile women.  A rise in LH at menstual midcycle predicts ovulation within about 24 hours.
