Got man boobs? Search has information about your condition, what it is and what you can do about it.

What it is. Of course, there's a technical name for it: gynecomastia.What does it looks?
Not surprisingly, real gynecomastia (see more on pseudo gynecomastia below) is often caused by an imbalance between the hormones testosterone and estrogen, both of which are naturally occurring in men.

You knew about testosterone, but yes, guys need estrogen, too.

There are other causes as well, including the use of some recreational drugs. At least one hair-loss drug may also cause it. Can't a guy get a break?

What to do.

As many as half of all adolescent boys show signs of gynecomastia during puberty. It makes gym class tough, but it also usually disappears in a couple of years.

It's a different story for adult men, for whom breast reduction surgery is a common form of treatment. Some dietary supplements purport to treat the condition. You'll have to judge those for yourself.

When it's not gynecomastia. Some man boobs, maybe even most, aren't caused by hormone imbalances at all. This would, of course, be pseudo gynecomastia.

For those cases, the problem is being overweight, and all the usual solutions apply. Chief among them: Put the cookie jar back on the shelf, get off the couch, and get some exercise.
