I haven't hit puberty, i am 16. i have pubic hair. one of my testicles is nearly double the size of the other which scares me. ?

Sounds like you: have it puberty. That's what pubic hair is all about. You probably have a deeper voice, emerging facial hair, broadening shoulders, elongation of limbs and facial bones, etc. A larger testicle isn't by itself such a big deal, unless it is painful, or causes dysfunction. But a check with your pediatrician wouldn't hurt.

See doctor.: Actually, pubic hair is a sign of puberty. Testicular size is worrisome, since testicular cancer can occur in young men. See a doctor.
