At which Tanner stage does puberty start?

Tanner Stage I
Tanner Stage II
Tanner Stage III
Tanner Stage IV

The correct answer is: Tanner Stage II

Puberty is characterized by physical and hormonal changes that lead to sexual maturation. The Tanner stages, also known as sexual maturity ratings, describe the development of primary and secondary sexual characteristics in children as they mature into adulthood. Tanner Stage II marks the beginning of these changes, which include the onset of breast development in girls and the enlargement of the testes and penis in boys. In girls, Stage II entails the appearance of breast buds and the growth of pubic hair. In boys, it involves testicular enlargement and the onset of pubic hair growth. This stage signifies the initial hormonal changes that trigger the broader processes of puberty. Knowing this helps reinforce the understanding of human development and the natural progression of bodily changes during adolescence.
