What makes early puberty more likely?

ANSWER

While they aren't necessarily causes, some things seem to be related to early puberty:

  • Gender. Girls are 10 times as likely to have central precocious puberty as boys.
  • Genetics. Precocious puberty can be triggered by genetic mutations that trigger the release of sex hormones.
  • Race. African-American girls seem to start puberty about a year earlier than white girls.
  • International adoption. Children who are adopted from overseas are 10-20 times more likely to develop precocious puberty.
  • Obesity in girls
