What happens during puberty?

Today, the first signs of puberty appear earlier than most parents expect. It begins with the production of sex hormones. On average, this starts as early as age 9 in girls and age 11 in boys. This triggers the gradual changes in the brain and body shape. Most girls reach sexual maturity by age 14, and boys by age 16. Physical growth takes a little longer. 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 their own pace. Deviations from these age ranges are completely normal and no cause for concern.
