Gynecomastia is when male breast tissue swells and becomes unusually large. It is a common condition that stems from a change in balance between the hormones testosterone and estrogen. Breast gland enlargement may affect males of all ages, including newborns, during puberty, and older adults. Gynecomastia is the result of additional breast tissue rather than fat. Exercising or losing weight will not reduce the breast tissue in gynecomastia.
