The term Male Breasts (gynecomastia, man boobs, moobs, moobies etc) covers a very common entity that ranges from a slight prominence of the breasts to hanging, deflated "old woman's breasts" - on men. The required correction to achieving a flat male chest would depend on the EXTENT of the breast deformity. In MOST cases liposuction with VASER (google the term and check out on youtube) coupled with surgical removal of some of the breast glad under the nipple complex works well in most men.
The VASER uses high pitched sound waves to dislodge the fat in the breast even when encased in fibrous tissue and make it easier to vacuum. It does so SELECTIVELY without permanently injuring nerves or blood vessels. The result is rapid healing with minimal swelling. In laser liposuction (such as SmartLipo etc), the fat is poked multiple times with an extremely hot laser fiber which cooks everything it touches - breast tissue, fat, nerves, blood vessels and skin. Not only is the operation longer but it creates a wider / deeper field of injury without ANY scientifically proven benefits.
Good Luck.
