Some men develop unwanted breast tissue (gynaecomastia) that causes social embarrassment. This can happen at any age but is more common in the late teenage years and mid life. For most the cause is unknown, but hormonal imbalance, anabolic steroid, prescribed or recreational drug use can also associated with this condition.

Reduction of the male breast should lead to a flatter and more defined masculine chest, which improves patient confidence. If liposuction only is used scars are small. If open surgery techniques are required, scars are more visible around the areola.
