Gynecomastia is over-developed or enlarged breasts in men – and is common in men of any age. It can be the result of hormonal changes, heredity conditions, disease or the use of certain drugs. Gynecomastia can cause emotional discomfort and impair your self-confidence. Some men may even avoid certain physical activities and intimacy simply to hide their condition. If you are interested in male breast reduction, consult with your plastic surgeon to find out if this procedure is right for you.
