What are the types of early puberty?

ANSWER

Central precocious puberty is the more common type. The process is identical to normal puberty, but happens early. The pituitary gland makes hormones called gonadotropins that in turn stimulate the testicles or ovaries to make testosterone or estrogen. It's these sex hormones that cause the changes of puberty, like breast development in girls.

Peripheral precocious puberty or precocious pseudo-puberty is a different condition and also rarer. The sex hormones trigger the symptoms, but the brain and pituitary gland aren't involved. It's usually a local problem with the ovaries, testicles, adrenal gland, or a severely underactive thyroid gland.
