Gynecomastia Audio (En español)

Development of larger-than-normal breasts in males. Gynecomastia is due to excess growth of breast tissue, not fat tissue. Gynecomastia is sometimes caused by natural hormonal changes, but it can also be due to use of certain medications, including antiretroviral (ARV) drugs.
