What causes true Gynecomastia?
Gynecomastia is usually caused by changes in hormones at puberty or as part of aging. Gynecomastia may be caused by changes in the balance of 2 hormones: estrogen and testosterone. In rare cases, Gynecomastia may be caused by prescription drugs, over-the-counter medicines, illegal drugs, tumors or disease. Are tests needed to find the cause of Gynecomastia?
