Puberty in boys

teenage boy
Most boys notice that their bodies start to change anywhere between the ages of 9 and 15. Some boys start and end puberty earlier than others.

Your body will begin to change on the outside. At the start you may experience a growth spurt, which means you grow taller in a short period of time. Some boys put on weight just before the growth spurt starts.

Hormones

During puberty, your voice gets deeper; you become more muscular, and your shoulders get broader. Hair begins to grow on your face, under your arms, and between your legs. You begin to sweat more and have body odour. You may also get spots or acne.

All these changes are normal, and are caused by hormones. They can also be affected by your diet, and hereditary factors including your ethnic background.

In general, puberty ends by the age of 18 or 19. By then, your body has matured into an adult body.
