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.
Puberty occurs during adolescence, which begins as early as age 10 and is usually completed by age 17. For girls, a rising level of oestrogen (female hormone) sets the process in motion. Pelvis and breast development are followed by a spurt in height and then the growth of underarm and pubic hair.
