Who do i ask about puberty and i haven't start it yet i'm 16 ?

The good news is the: lateryou hit puberty, the taller you'll be. See you our primary care doctor, who will look for signs of testicular enlargement, which should happen by 14 ½. If your doctor has any concerns, you'll see a pediatric endocrinologist. It will be worth to know if you have anything to worry about, or if you can sit back, relax, grow taller & have the last laugh on the high school jocks.
