  *Puberty onset occurs for boys at a median age of 11.5 years. For boys there is no proven relationship between puberty onset and body weight or ethnic origin. Progression through Tanner stages is variable. Tanner Stage V (adult) should be reached by age 18.   *Puberty onset (transition from Tanner Stage I to Tanner Stage II) occurs for girls at a median age of 10.5 years. There is evidence that it may occur up to 1 year earlier in obese girls and in African American girls. Progression through Tanner stages is variable. Tanner Stage V (adult) should be reached by age 18.
