Puberty is started by hormones, which are chemicals that tell parts of the body to do things. Today, on average, girls start puberty at age 10 or 11, and boys at age 11 or 12. However, people all over the world start puberty at different ages. girl who has gone through puberty can become pregnant and have a baby. At puberty, a boy's body begins making sperm and he starts to be able to ejaculate, which is semen coming out from his penis when he is sexually excited.
