Gynecomastia is an enlargement or swelling of breast tissue in males. It can affect one or both breasts. Gynecomastia is most commonly caused by an imbalance between the hormones estrogen and testosterone. Estrogen controls female traits, including breast growth. Testosterone controls male traits, such as muscle mass and body hair. Although each of these hormones produces the usual traits seen in males and females, males produce a small amount of estrogen and females produce a small amount of testosterone. Male estrogen levels that are too high or are out of balance with testosterone levels cause gynecomastia.

Sex, sunbathing by the pool, charging into battle on horseback — there are certain things in life that are best enjoyed without a shirt on. Regardless of how you grew them, your man-nary glands can be remedied. Of all the indignities age thrusts upon your body, a sudden swelling in your chest might be the toughest to stomach. Man moobs are caused by the formation of excess fat or breast tissue, which gives the appearance of breasts. For sufferers, it can be an extremely embarrassing issue, leading to problems with self-esteem, body confidence and an overall decline in mental well-being. In most cases, this is a combination of fat and gland, but mainly fat. The cause of this is weight fluctuation.

Read our blog about breast cancer in men. Though boys and girls begin life with similar breast tissue, over time, men don't have the same complex breast growth and development as women. At puberty, high testosterone and low estrogen levels stop breast development in males.
Men who have suspicious physical findings or any persistent signs and symptoms should make an appointment to see their health care provider. If deemed appropriate, your health care provider may refer you to the Carol Milgard Breast Center for a diagnostic mammogram. Don't delay the possibility of an early diagnosis.
