All bodies:

• You may get acne (AKA zits or pimples) on your face and body. If pimples are stressing you out or causing problems in your life, talk to a doctor.

• You start to sweat more, and you may have body odor (when your sweat smells bad). You may want to shower more and start using deodorant.

• Hair grows under your armpits.

• Hair grows around your genitals — this is called pubic hair.

• You may grow more hair on your arms and legs, and the hair may get darker.

• You may feel some pain in your arms and legs as you grow (AKA “growing pains”)

Males:

• Your voice gets lower or deeper. It may crack sometimes while it’s changing, but that’s totally normal and eventually goes away. Your Adam’s apple (bump in your throat) might get bigger and more visible as this happens.

• Your penis and testicles get bigger.

• Hair may grow on your face, chest, and back.

• Your chest and shoulders get broader.

• You may have swelling around your nipples during puberty. This can look like the start of breasts,  but it usually goes away. This happens to about half of males, and it can last for a few months or up to a few years.
