What is Precocious Puberty (Early Puberty)?

Early puberty is also called precocious puberty. Puberty is thought to be early in girls before the age of 8 and in boys before the age of 9. Most children with early puberty grow fast at first, but finish growing before reaching their expected adult height. Early puberty will cause a child’s body to change much sooner than their friends. They may feel different than their friends and feel uncomfortable with their body changes.

What Causes Precocious Puberty?

Early puberty is caused by hormones from the reproductive glands or special glands called adrenal and pituitary glands. A family history of early puberty, genetic syndromes, brain injury, or side effects of brain cancer treatments may also be a cause.

How is Precocious Puberty Treated?

Some children do not need treatment for precocious puberty. If your child needs treatment, the provider will order medication to stop puberty. Your healthcare provider will talk with you about what is best for your child.

Call Your Doctor

Call your healthcare provider if you have concerns or you notice more signs of early puberty.

It is very important to have regular follow-up appointments (every four to six months) with your pediatric endocrinologist.
