Answer 2

The changes that happen during the process of puberty have a typical pattern in both boys and girls, with a generally predictable sequence of events. In most girls, the first sign of puberty is the beginning of breast development (breast buds), which occurs at an average age of approximately 11 years. In girls, the growth of pubic hair typically begins next, followed by the growth of hair in the armpits. A minority of girls, however, begin to develop pubic hair prior to breast development. The onset ofMENSURATION(having periods) usually happens later than the other physical changes and usually occurs around two and a half years after the onset of puberty.

A regular pattern of OVULOTION, corresponding to achievement of fertility, usually develops rapidly once a girl begins having menstrual periods. However, girls who have a later onset of menstruation (after age 13) tend to have lower rates of regular ovulation in the years following the onset of menstruation. Studies have shown that one-half of adolescent girls who first begin to menstruate after age 13 will not ovulate regularly over the next four and a half years.

In boys, an increase in the size of the testicles is the first change observed at the onset of puberty. Enlargement of the testicles begins at an approximate average age of 11 and a half years in boys and lasts for about six months. After enlargement of the testicles, the penis also increases in size. Enlargement of the testicles and penis almost always occurs before the development of pubic hair. The next stage is the growth of pubic hair and hair in the armpits. Next, the voice becomes deeper and muscles increase in size. The last step is usually the development of facial hair.

Fertility is achieved in males near the onset of puberty, when a surge in testosterone triggers the production of sperm.
