Is there an effective exercise to reduce mons pubis fat?

Fat can be localized in some unusual places and the mons is one of them. Wthout surgery to reove fat from the area, I am afraid that I know of no exercise that will accomplish this. Good luck. Dr PG

It's possible that with weight loss the Mons might get smaller but not necessarily. In about 15 minutes under local anesthesia you can have the excess removed never to return.

      The only way to reduce it is overall body fat loss.  This is a difficult area for most people, and liposuction is a reasonable tool for removal.Kenneth Hughes, MDLos Angeles, CA
