What are signs of early puberty?

ANSWER

They're the same as puberty -- it's the timing that's different.

In girls, starting before age 7:

  • Breast development (often the first sign)
  • Menstruation, typically 2-3 years after earlier symptoms start

In boys, starting before age 9:

  • Growth of the testicles, penis, and scrotum
  • A deepening voice, usually later

Growth spurts are another sign of early puberty in both girls and boys.
