Gynecomastia /ˌɡaɪnɨkɵˈmæstiə/ is a common condition characterized by the benign enlargement of breast tissue in males. It may occur transiently in newborns. Half or more of adolescent boys have some breast development during puberty. Newborn and adolescent males frequently experience temporary gynecomastia due to the influence of maternal hormones and hormonal changes during puberty respectively.
