What are the main things that cause man boobs?

I’ve never really been overweight. I put on a few pounds in college like most people, but I’ve always considered myself normal weight. I suffer from man boobs though and I want to know what causes this. Is it just genetic? My dad doesn’t have man boobs.

Gynecomastia, or "man boobs", is due to excess breast tissue in a male.  Causes include hormonal imbalances, medication side-effects,  and genetics.  Many cases are "idiopathic", which means you have it and we don't know why you have it.  Fortunately, gynecomastia is very correctible with a simple surgical procedure.  After ruling out other causes of the gynecomastia, the surgical procedure involves a small incision with removal of the breast tissue, and often liposuction to contour the surrounding areas.  It is an outpatient procedure with a 5-7 day recovery.
