If you are a boy between the ages of 8 and 12, you have probably noticed some changes in your body. These changes are called puberty. Puberty is the general name for the process everyone goes through to change from a kid to an adult. Some of the changes are physical and some of the changes are emotional.
Puberty takes place over several years, and while it may seem like the process will never end, most boys are through puberty by age 16 or 17 or so.
