Male breast reduction surgery (gynecomastia) removes excess breast tissue that may have developed as a result of puberty or exposure to steroids. Depending on the extent of the condition, surgery may involve liposuction alone or require excision of breast tissue.

In cases where there is excess skin or the areola is enlarged, skin can be removed while hiding the scar at the areola border.

When the nipples droop (such as in cases of large weight loss), the nipple areolas may need to be removed from their abnormal position and sewn on to the new position higher on the chest. Recovery usually takes about one week, but a compression shirt is worn for six weeks.
