when you go through puberty what happens
Puberty is a major change that happens in your body. It is a time when you grow very fast and your body changes into an adult body. Puberty usually starts between ages 10 to 14 in boys, but it may start earlier or later. You may not go through puberty at the same time or in the same way as friends your age do. Puberty usually ends by about age 15 or 16 in boys.
During your teenage years, your body will go through several changes as you become an adult. This body development is called puberty. At the start of puberty you will notice hair growing around your penis, under your arms, and on your face, chest, and legs. Your testicles and penis are also growing. You may develop acne (pimples).
Puberty Breast Development. Breast development is an early sign of puberty in girls. This can happen before age 9 in some girls, but later in others. If you are self-conscious, you might want to start wearing a training bra, which is a soft bra with no real support. Talk to your mom, older sister, or an aunt about buying a training bra.
