Gynecomastia, for a lot of men usually clears up after a few month to a few years when they first notice the problem.  For the others it is a lot more persistent and can continue to have this for long period of time spanning over many years.

It is extremely common in boys who are going through puberty because of all the intense hormonal changes taking place in their bodies. Like my doctor told years ago when i first noticed it.

This shift in hormonal changes can not only affect the young but also the older men as their bodies adapt to the levels of testosterone in their bodies as the levels begin to drop naturally with their age.

It is widely accepted between doctors and in medical journals that there are imbalances between sex hormones testosterone and oestrogen in men with gynecomastia. However there are no real indications of what exactly triggers this.

I found some popular theories which show some of the possible triggers.

  • Klinefelters Syndrome (genetical) Klinefelters syndrome is a condition that occurs in men who have an extra X chromosome in most of their cells
  • kidney diseases and/or Chronic Liver disease
  • Trauma or injury to the testicles[1]
  • Side effect of medication.

Our daily lifestyle can also be a trigger:

  • Excessive marijuana use. Some studies have shown that cannabis can contribute to a lowering of testosterone levels as well as a decreased sperm count. However there are varying levels of arguments if it 100% does or does not.
  • Excessive alcohol consumption. It’s well known how alcohol inhibits testosterone in the short term. This is 100% proven factor.
  • Use of anabolic steroids. Initially these drugs create huge spikes in the body’s testosterone levels. The irregular levels of taking steroids makes the body unable to cope with the change in the level of testosterone when the person comes off his cycle of using the drug. So what happens is there is an inbalance of testosterone and oestrogen.
  • Obesity. Excessive levels of fat can lead of course to store of unwated fat in the chest area and pseudo-gynecomastia.
