[5] In HIV treatment, the Tanner scale is used to determine which regimen to follow for pediatric or adolescent patients on antiretroviral therapy (adult, adolescent ...

[7] Additionally, secondary breast development occurring before the age of 7 years could be a sign of premature thelarche or precocious puberty. Of note, for some girls ...
Puberty onset before the age of 9 in males is considered medically abnormal, and is defined as precocious puberty; Research on both organic and ideopathic precocious puberty in males has described puberty onset as early as nine months old, [11] [12] as semenarche has a wide range of onset within puberty (with some research indicating spermatogenesis in some cases in early pubertal development ...
Puberty usually begins around ages 10—11 in females and around ages 11—12 in males. [7] Body weight and nutrition status is evidenced to have an effect on puberty onset as well, due to some input from adipose tissue hormonal signaling.
