Answer 1

Precocious puberty occurs when boys develop secondary sexual characteristics before age 9 and girls before age 8, which is earlier than the normal puberty onset ages of 11-12 for boys and 9-10 for girls.

Step-by-step explanation:

Precocious puberty is defined as the development of secondary sexual characteristics in boys before age 9 years and in girls before age 8 years.

This condition means that the physical signs of maturation occur earlier than the typical age range of puberty. For boys, puberty normally begins between the ages of 11 and 12, while for girls, it generally starts between 9 and 10 years of age.

One of the most significant changes during puberty includes the development of secondary sex characteristics such as growth of facial hair and deepening of voice in boys, and breast development in girls. Puberty involves both physical and hormonal changes, including the increase in size of testes and scrotum in boys, and the maturation of female reproductive organs such as the uterus and ovaries leading to the onset of menstruation.
