Under certain circumstances, a man can develop fibro-fatty breast tissue that resembles a woman’s breast. This condition is referred to as gynecomastia. The etiology of this process is not widely understood, however, it is known that certain medical conditions, medications, hormones, drugs, and other factors may play a role. In the majority of cases, no etiology can be determined. Gynecomastia affects an estimated 40 to 60 percent of men, and it may affect one breast or both.
Depending on the extent of the problem, gynecomastia may be treated with excision of the breast bud, liposuction of the fatty tissue, or a combination of both procedures. Occasionally, a secondary procedure to reduce excess skin or to return the nipple to a more normal position may be needed. Results can vary, but generally, patients have a chest that is flatter, firmer, and better contoured, and they often feel more comfortable in form-fitting clothing or going without a shirt.
