Boys/girls in puberty

Worth knowing about gender-typical development

.
Jungen Mädchen Pubertät

What happens during puberty?

The first signs of puberty today appear earlier and earlier than most parents expect. It begins with the formation of sex hormones. In girls, this occurs on average from the age of 9, in boys not until the age of 11. This is the trigger for the gradual remodeling of the brain and body shapes. Most girls reach sexual maturity at age 14, boys at 16. Body growth takes a little more time. It usually ends around age 16 for girls, but not until age 19 or 20 for boys. Please note: These figures are averages. Every child develops at his or her own pace. Deviations from these ages are completely normal and no cause for concern.
