Gynecomastia
Gynecomastia is the enlargement of the breast tissue in males that causes a kind of female breast appearance. Gynecomastia can occur in one or both breasts and may involve excess breast tissue as well as fat tissue.
Although gynecomastia may result from a hormone imbalance that decreases testosterone and increases estrogen and accompany some congenital abnormalities involving sexual characteristics, it is usually seen on its own. The otherwise normal boys tend to be overweight and sedentary. It is not surprising to see these patients start going to gym, lose weight and become fit after gynecomastia is operated.
