Gynecomastia is enlargement of the breast tissues in boys or men. Both men and women have breast tissues and being control by our body hormones. “Male” hormone testosterone and “female” hormone estrogens are present in both men and women. For men level of testosterone is higher than level of estrogen, so men don’t grow boobs. Changes in balance of hormones in male causes the breast tissue grow and develop gynecomastia.





  • Gynecomastia in teenagers – Breast tissue growth happens in men during three stages in the life span of an individual and they are infancy, adolescence and old age. When teenagers go through puberty and becomes sexually mature, there are a lot of hormonal changes including estrogen dominance for some time and this can cause development of breast tissue. Not all boys going through puberty will experience this but estimated 50% may develop breast tissue growth. This called pubertal or teenage gynecomastia.
  • Gynecomastia in adults– Men who are significantly overweight are very likely to feel some enlargement of their breast tissue. This is partly caused by fat tissue under the skin on the chest wall, and partly by true breast glandular tissue. Fat tissue anywhere in the body encourages formation of estrogen, and thus can lead to gynecomastia.

Gynecomastia surgery

Gynecomastia maybe not a serious problem, but it can cause emotional discomfort, embarrassment and impair self-confidence. To avoid these situations some men choose to undergo a surgery to remove the breast tissue. The type of surgery the doctor will recommend will based on his evaluation. The surgery usually carried out by a plastic surgeon and done it in an outpatient visit.


Proper investigations and evaluation needed to work out the cause of the problem, these include the following:

  • Physical examination
  • Blood tests
  • Ultrasound scan of the breast tissue
  • Other scans like MRI of the breast area

Types of surgery for gynecomastia we offer here at Rattinan clinic:
