I'm 18 and don't have a lot of facial hair, my genitals haven't seem to grow much. my voice has changed and i have armpit hair tho. low testosterone?

Testosterone: Greetings. Yes, I would check with your family doctor with these issues. A complete hormonal work up is in order. Good luck.

How's it working?: If you're horny like other guys your age, and are having erections and ejaculations like they are, then things are going to be fine. Around 5% of men never get chest or good facial hair. Mr. Newman (photo), considered the best-looking male specimen of his age, never complained. If you're not having an ejaculation at least every few days, get with your personal physician now.
