Central Precocious Puberty, CPP, is a rare condition — occurring in 1 out of every 5,000 to 10,000 children — in which puberty begins before age eight for girls, and before age nine for boys. The condition is more common in girls. Puberty is challenging at any age, but unusually early puberty can have adverse effects on social behavior and psychological development, can reduce adult height potential, affect bone growth and may shift some lifelong health risks. In certain rare cases, these signs may also indicate the presence of an underlying condition. It’s critical to consult with a pediatrician if a child shows signs of CPP, such as body odor, body hair, acne/oily skin, breast buds in girls, mensuration or moodiness. Learn more about CPP from Sonya McTillman, Director of the Precocious Puberty Division of the Magic Foundation, and mother of a daughter diagnosed with CPP.
