Gynecomasty is the abnormal development of mammary glands in men, causing a breast augmentation.

Around 65% of the population aged 13-16 years of age suffer from this. At this age, the hormonal changes that occur, stimulate the growth of the mammary gland leading to the presentation of gynecomasty. Between the ages of 40-50, about 40% of men can present it.

In both situations, gynecomasty is caused by alterations in hormone metabolism, due to anabolic steroid use, liver disease (cirrhosis), lung cancer, testicular disease, adrenal gland disease, or pituitary disease.

The use of drugs such as captopril, methyldopa, cimetidine, ketoconazole, diazepam, finasteride, among others could cause the increase of mammary glands.


All male patients who develop abnormal breast augmentation.


The objective is to revert the process through the removal of excess skin, fat, and mammary tissue. This way a more comfortable volume is given, featuring a new shape, firmer consistency and and adequate positioning.

Techniques vary with the size of breast tissue, the amount of skin that needs to be removed, and existing fat volume.

If the breast tissue has excess skin, a technique with removal of breast tissue and skin will be used.

If it is only fat, liposuction in the affected area would be enough.
