I have loose/extra scrotum skin cause i used to pull my testicles to scratch because of jock itch.can the loose skin be eliminated by surgery ?

I'll bet you're fine: Here's the score. At you're age, you're still learning about your body. Skin on the scrotum varies from loose to tight depending on the state of the dartos muscle -- the smooth muscle that automatically contracts when you take a cold shower -- and just how a guy is put together. You really can't grow new skin just by scratching. Talk with your physician next visit or talk with friends or even Dad.
