There is a rare condition in which male's breast tissue enlarges significantly, developing breasts similar in size and shape that those of women. This problem is known as Gynecomastia, a Greek term meaning "woman" (gyne) and "breast" (mastos). Although, the causes of this alteration are unknown, the condition occurs more often in neonates, adolescents, and elderly men.

Male breast reduction is not recommended in adolescents since they may suffer Pubertal Gynecomastia, a condition that make their breasts shrink and disappear after a few years. Many male children and teenagers have larger breasts as a result of obesity which will return to their normal size after weight loss.

It is believed that breast enlargement in men are the results of sex hormone imbalances and tissue responsiveness to hormones. Approximately 40 to 60% of all men have developed some form of Gynecomastia in one breast or both breasts. Although, many doctors recommend drugs specially designed to reduce this problem, an easy male breast reduction surgery can save them from embarrassment in shorter time.

Male breast reduction surgery removes fat from the men's breasts, although sometimes it is pure glandular tissue the factor that overdevelops their breasts, along with excess skin in less common cases. In some of them, men develop woman-like breasts after being prescribed hormone treatments

Pectoral adipose tissue is cut out with a scalpel. Depending on each individual case, the procedure can be performed alone or in conjunction with liposuction to remove all the fat. In fact, surgery can be reduced to a simple liposuction when breasts are the result of excessive fatty tissue, in which case, a small incision is made around the edge of the areola.

Both the excision and liposuction may cause discomfort for a few days following a male breast reduction surgery, which is often alleviated with medication prescribed by the plastic surgeon. Because breast enlargement in men could cause teasing and social trauma, Surgeons encourage men to take action and get rid of the problem.

Male breast reduction enhance men's appearance and self-confidence. However, this procedure is not intended for body building, just reducing the size of the breast to recover their original flat dimension. People who want to change the shape of their chest should discuss with the surgeon other options apart from this operation.

Furthermore, obese men should not consider Male breast reduction as the easiest solution for their overweight problems. Because morbid obesity makes it harder to diagnose Gynecomastia, patients should discuss the problem with both a surgeon and a health care provider specialized in obesity.

Men with elastic, firm, skin and average weight, are the best candidates for undergoing this procedure. People can return to works in a few days after surgery, but is usually advised to avoid sexual activity for a week or two. Men must also avoid sun for the following six months or so, in order to avoid the ultraviolet rays that may cause permanent damage to the skin pigmentation of scars resulting from the procedure.
