What is Gynecomastia?

Gynecomastia is a medical condition that causes men to grow excess breast tissue. Enlarged male breasts have a feminine look which often causes embarrassment along with physical discomfort. Gynecomastia symptoms include puffy nipples, enlarged areolas, firm lumps of glandular tissue, tenderness, and pain. In rare cases, the nipples may secrete fluid.

What Causes Gynecomastia?

Gynecomastia is often caused by hormonal changes onset by puberty (adolescent gynecomastia) but anabolic steroid use among muscle builders is also a common cause (steroid-induced gynecomastia). Hormonal changes later in life can also cause adult gynecomastia to develop. If the male hormone levels are unbalanced and too much estrogen is being produced, this causes the growth of excess glandular tissue in the chest region. Other possible gynecomastia causes include the use of certain antidepressants or antibiotics and illicit substances such as marijuana and heroin.

Miguel A. Delgado, MD, FACS

Board-Certified Plastic Surgeon

Dr. Miguel Delgado M.D is a renowned gynecomastia specialist and the authority figure behind Gynecomastia.org, the leading online gynecomastia forum. Established in 1986, the forum has provided gynecomastia information and resources for over 30 years.


Pseudogynecomastia is often mistaken for “true” gynecomastia but there is a significant difference between the two conditions. Pseudogynecomastia is caused by a buildup of fat, not glandular tissue. Unlike true gynecomastia, it can often be treated with exercise and diet or less invasive surgical methods like liposuction.

After delaying many years and speaking with multiple plastic surgeons I chose Dr. Delgado and so glad I did! Only 4 weeks after my procedure, recovery is going smooth and the results have already exceeded my expectations! I highly recommend Dr. Delgado!


Quotation Marks

I researched both gynecomastia and plastic surgeons for a year before having my procedure. There’s a reason Dr. Delgado has so many 5 star reviews. He is an expert among experts in this field and this is not the kind of procedure you want to have revised. His expertise and skill is worth every penny and having this procedure is one of the best decisions I’ve ever made. Every member of his staff goes above and beyond. You will not be disappointed.

Gynecomastia Surgery

Gynecomastia surgery or male breast reduction surgery can be performed to remove the glandular breast tissue and create a more contoured, masculine chest. Different surgical techniques can be used depending on the severity of each patient’s gynecomastia. Grade 1 or 2 gynecomastia is categorized by a minimal amount of breast growth and can be successfully treated with smaller incisions combined with liposuction. Grade 3 or 4 gynecomastia is a more severe case in which the male breasts are sagging (resembling female breasts) and there is often excess skin that must be removed along with the glandular tissue.

The standard surgical technique for a male breast reduction procedure is performed under light general anesthesia. Dr. Delgado will start by making an incision in the armpit, along the breast fold, or around the areola. Liposuction removes excess fatty tissue and sculpts the chest for a toned, masculine appearance. Next, the skin is lifted, and glandular tissue is removed in small pieces until a smooth, toned appearance is achieved. After the surgery is complete, a specialized compression garment designed by Dr. Delgado is placed around the chest to compress and shape the newly contoured chest.

Gynecomastia Revision Surgery

Corrective surgery to improve the results of an initial operation is more difficult, which is why it is important to seek out a gynecomastia expert like Dr. Delgado. Patients may need gynecomastia revision surgery because liposuction was used without excision, not enough glandular tissue was removed, or a crater deformity developed in the chest contour. Gynecomastia revision surgery involves the same techniques as gynecomastia surgery, but special care will be taken to ensure optimal results are achieved.
