You're problem might also be hormones related, There are currently no "official reason" for man boobs, but a lot of cases demonstrate that it is often related to hormones imbalance. I would recommend you seek your doctors advice.
As for
exercises to get rid of them, i would recommend
cardio, bench press and push-ups. These will probably not remove your man boobs completely, but it's a step in the right direction.
Just my 2 cents
