Will Masturbation in Puberty Increase Gynecomastia?

Masturbation does not cause gynecomastia. There are many theories about what causes it, but there is no definitive answer.  Many healthy, athletic males, including athletes with low body fat can have gynecomastia. Having gynecomastia is not your fault.  Many males, including many teens suffer with gynecomastia. For some teens, the gynecomastia will go away in time. For others, it won't go away. I would encourage teens to discuss this with their parents, and I would encourage parents to discuss this with their teens. A male does not have to live with gynecomastia. Surgery, when expertly performed can leave the chest looking and feeling smooth and even. Ideally, scars will ultimately fade to barely perceptible. 

Hi Tonystark,Thanks for the post. First of all masturbation does not cause gynecomastia. If it did, every male would have gynecomastia. The most common cause of gynecomastia in your age group is due to hormonal changes as you go through puberty. This is referred to as physiologic gynecomastia and in a large number of teens it goes away after a few years. If your gynecomastia has not gone away after several years and you have no other medical issues that could have caused it, then you could be a candidate for surgery. Sincerely,Dr. Dadvand
