What is Puberty?
Puberty means the body changes from a child to an adult. Boys' bodies grow bigger and stronger. Their voices get deeper. Hair grows in new places. These changes prepare the body to become an adult man.
Puberty happens because of hormones. Hormones are chemicals in the body. The main hormone for boys is called testosterone. It starts working when the brain tells the body to begin puberty.
