Gynecomastia

Gynecomastia is enlargement of the male breast caused by an imbalance in hormones estrogen and testosterone. Physiological gynecomastia may be observed in new born boys, pubertal teenage boys and older men because of natural hormonal changes. Pathological enlargement may occur in some other diseases due to hormonal imbalance like genetic factors, obesity, medications like anabolic steroids, chronic alcoholism and drug addiction.
