Normal Puberty. The time in one's life when sexual maturity takes place is known as puberty. The physical changes that mark puberty typically begin in girls between ages 8 and 13 and in boys between ages 9 and 14. Precocious puberty is a condition that occurs when sexual maturity begins earlier than normal.
Average Age of Puberty in Boys. Puberty generally begins later in boys, at an average age of 11 1/2 to 12 years, with a normal range being considered from 9 to 14. The first sign of puberty in boys is an increase in size of the testicles. This is followed a few months later by the growth of pubic hair.
