What is puberty?

Puberty is a period during in which a growing boy or girl undergoes on the process of sexual maturation. Puberty involves a series of physical stage that lead to achievement of fertility and development of secondary sex characteristics.

The onset of puberty varies among individuals but usually between 10-14 years in girls and 12-16 in boys. The changes that happen during the puberty have a typical pattern. The first sign of puberty in girls is breast development (breast buds) which occur at an average age of 11 years. The growth of pubic hair begins and next followed by the growth of hair in the armpit. The onset of menstruation (having period) happen later around two and half years after the onset of puberty. Regular ovulation usually develops rapidly once a girl begins having periods.
