Hi, I was wondering what hormones would be responsible for growth of the penis/teste region? HGH or testostrone? I am still growing i feel (17years old) but i feel if i was to take HGH or testostrone it would help me grow down there. Is this true? I feel like as i am still young i can change it chemically; I wanna do it before its too late. Any help would be great! Thanks!

Get your male & female hormones tested. If they are out of balance with estrogen too high or testosterone too low it can prevent penis & testicle growth in puberty.

If the estrogen is too high you may start growin breasts also.
