Gynecomastia(redirected from M00b)
Also found in: Dictionary, Thesaurus, Medical.
excessive unilateral or bilateral enlargement of the mammary glands in males, so that they sometimes resemble female glands. Temporary, mild gynecomastia often occurs in adolescent males. Pronounced gynecomastia is one of the symptoms of primary diseases of the endocrine glands, especially the gonads. Patients develop secondary female sex characteristics (feminine pelvis, hips, and voice), lose facial hair, and suffer sexual disturbances. Gynecomastia can also develop in cases of liver diseases (cirrhosis), because of disturbances in estrogen metabolism. Treatment involves elimination of the main disease and sometimes surgery.
