Information

The exact age a child enters puberty depends on a number of different things, such as a person's genes, nutrition, and gender. During puberty, various endocrine glands produce hormones that cause body changes and the development of secondary sex characteristics. In girls, the ovaries begin to increase production of estrogen and other female hormones. In boys, the testicles increase production of testosterone.

The adrenal glands produce hormones that cause increased armpit sweating, body odor, acne, and armpit and pubic hair. This process is called adrenarche. The adolescent may find that an underarm deodorant or antiperspirant becomes necessary.

PUBERTY IN GIRLS

Breast development is the main sign that a girl is entering puberty. This will be followed by the first menstrual period (menarche). Before having the first menstrual period, a girl will normally have:

• An increase in height
• Pubic, armpit, and leg hair growth
• Clear or whitish vaginal secretions
• Increased hip size

Menstrual cycles occur over about one month (28 to 32 days). At first, the menstrual periods typically are irregular.
