The Facts about Puberty (for Guys)


WebMD Feature

"I'm getting hair in places I've never had hair before ... My voice is changing ... I think I've grown another inch overnight." This happens to every guy (and girl - but differently). It's the time when you physically stop being a boy and begin to transform into a man. It's when hormones in your body take over and cause things to change, grow, and develop. It's called puberty. Technically speaking, puberty is your body's way of transforming you into an adult, all for the sake of reproduction.

Starting at around age 13 or 14, you undergo a number of changes. Your ears, hands, and feet grow larger. You get taller and bulkier. Your shoulders broaden and your muscles get stronger. Your penis and testicles (balls) increase in size, as do your breasts (just temporarily, so chill!). Also, during this time, the testes will begin to produce a hormone called testosterone as well as produce sperm.

Testicle Self-Exam

You may not give cancer much thought, unless someone you know has it. Even then, it's often someone who's older. You may think you're too young to worry about it. But you're not, especially if you’re over the age of 14. Testicular cancer typically affects males between the ages of 14 and 35. And it's the most common cancer in this age group. But there is something you can do to protect yourself. It's called a testicle self-exam. If you do one every month, your chances of finding cancer early are...

Your voice will begin to deepen, and you will begin to grow hair on your face and under your arms, as well as pubic hair.

Of course, no one can predict just when this will happen. It happens gradually over a period of time. Sometimes the transformation from a boy to man can take up to four years. Some males continue growing as late as age 21!

Here are some questions and answers about male puberty:

Q. I woke up and I can't talk in my normal voice. I try to sing, and I croak. When I talk, I sound like a rooster! I'm so embarrassed.

A. You can thank the androgens in your body for that. Androgens are hormones that control your male characteristics. They increase the size of your larynx (or voice box). Your larynx and the folds around it will thicken, and increase the lower tones or frequencies of your voice. While this is happening, you may experience periods of voice "cracking." The good news is that it's just a matter of time before you finally adjust to your lower voice -- although you may have a challenge singing for a while.

Q. All of my friends in PE class have pubic hair and their voices are changing. When is that going to happen to me?

A. Soon enough! Puberty does not begin at the same time for everyone. Puberty can begin as early as 10 for some guys, and as late as 14 for others. Many factors determine when your body will start changing. They include genetics (if dad was late to reach puberty, you might be late), physical health, environmental factors, and nutrition.

Q. I woke up and my penis was hard, and there was a wet spot where I was sleeping, but I didn't wet the bed. Is this normal?
