About CPP

  • CPP is when puberty starts sooner than it should. For girls, that's before the age of 8, and for boys, before the age of 9
  • CPP can affect your child’s adult height and their emotional well-being
  • If left untreated, children with CPP will keep going through puberty and that can have lasting complications beyond childhood

If you suspect that your child has CPP, don't wait—act now and notify your child's pediatrician. They can refer you to a pediatric endocrinologist who can appropriately diagnose your child and determine the right treatment plan for them.

POTENTIAL COMPLICATIONS
OF UNTREATED CPP

Shorter adult height

Children with CPP may be significantly taller than their peers, but if left untreated, it can cause shorter adult height.

  • CPP starts as an early growth spurt
  • This can cause the bones to mature more quickly than normal and the growth plates to close too early
  • Once the growth plates close, the child stops growing, which may lead to shorter adult height

Other ways children may be affected by CPP:

  • Children with CPP may face a series of struggles because they look older than they are
  • Everyday situations and interactions with their peers can become big challenges for them

Don’t wait–act now!

If you’re worried that your child may have CPP, talk to their pediatrician and ask for a referral to a pediatric endocrinologist. With an appropriate treatment plan, you can help control your child’s CPP.

IMPORTANCE OF DIAGNOSING 
AND TREATING CPP EARLY

Diagnosis involves consulting a doctor and conducting several tests, including:

  • Thorough physical examination
  • X-ray of hand and wrist (helps determine bone age)
  • Blood test
  • Gonadotropin-releasing hormone (GnRH) stimulation test
  • Pelvic or adrenal ultrasound
  • MRI or CT scan
