A problem that occurs in males, due to swelling of the breast tissue, is called gynecomastia. The reason for this swelling is a hormonal imbalance. The hormones in question are testosterone and estrogen. The condition makes the breasts of males look larger than the average male chest, and this can be the cause of some embarrassment in boys and adult males. One or both breasts can be affected, sometimes quite unevenly, and this causes more psychological discomfort to the affected male. There may be some physical discomfort in the form of pain. Some boys and men experience a little tenderness in the breast area. This imbalance can occur and develop at any stage in life. This may be due to a normal alteration in hormonal levels. The condition may disappear on its own. In case it persists, medication or surgery is an option to consider.
