What are the causes of Precocious Puberty?

Puberty usually begins between ages 8 and 14 for girls and ages 9 and 16 for boys.

The exact age a child enters puberty depends on a number of factors, including family history, nutrition, and sex.

Most often there is no clear cause for precocious puberty. Some cases are due to changes in the brain, genetic problems, or certain tumors that release hormones. These conditions include:

  • Disorders of the testicles, ovaries, or adrenal glands
  • Tumor of the hypothalamus (hypothalamic hamartoma)
  • Tumors that release a hormone called human chorionic gonadotropin (hCG)
What are the symptoms of Precocious Puberty?

In girls, precocious puberty is when any of the following develop before age 8:

  • Armpit or pubic hair
  • Beginning to grow faster
  • Breasts
  • First period (menstruation)
  • Mature outer genitals

In boys, precocious puberty is when any of the following develop before age 9:

What are the current treatments for Precocious Puberty?

Depending on the cause, treatment for precocious puberty may include:

  • Medicines to stop the release of sexual hormones, to help delay puberty. These medicines are given as a shot (injection). They will be given until the normal age of puberty.
  • Surgery to remove a tumor.

Children with early sexual development may have psychological and social problems. Children and adolescents want to be the same as their peers. Early sexual development can make them appear different. Parents can support their child by explaining the condition and how the doctor plans to treat it. Talking to a mental health worker or counselor may also help.
