Human genes for gynecomastia
Gynecomastia or Gynaecomastia, /ˌɡaɪnɨkɵˈmæstiə/, is the abnormal development of large mammary glands in males resulting in breast enlargement. The term comes from the Greek γυνή gyné (stem gynaik-) meaning "woman" and μαστός mastós meaning "breast." The condition can occur physiologically in neonates (due to female hormones from the mother), in adolescence, and in the elderly (Both in adolescence and elderly it is an abnormal condition associated with disease or metabolic disorders). In adolescent boys the condition is often a source of distress, but for the large majority of boys whose pubescent gynecomastia is not due to obesity, the breast development shrinks or disappears within a couple of years.
