Hey there!

Puberty is responsible for all of the hormonal changes your body goes through as you change from a child to an adult. Boys go through puberty later than girls. A pea-sized gland near your brain called the pituitary gland releases chemical substances called hormones.

In girls, these hormones are estrogen and progesterone. Usually around the age of 10 or 11, these hormones tell a girl’s ovaries to start releasing an egg each month. Breasts will start to develop, padding will develop on the hips, hair will grow on the pubic area and underarms, and menstruation will start.

In boys, puberty usually starts around the age of 12 or 13, when the pituitary gland tells the testes to start making sperm by letting out more of the hormone called testosterone. Much like girls, hair will start to grow on the pubic area and underarms; however, in boys, hair grows on the face and rest of the body, too. In addition, a male’s muscles, genital organs, and larynx enlarge. The enlarged larynx makes the young man's voice deeper. Aside from physical changes, kids going through puberty feel some emotional changes, like becoming interested in each other.

Everyone goes through puberty when their body is ready. Although some of these changes might sound scary, it’s perfectly normal and natural, so there is nothing to worry about. You will be just fine!
