The Life Cycle


A woman’s body goes though many important changes during her life—at puberty, during pregnancy and breastfeeding, and when she stops being able to have a baby (menopause).

In addition, during the years she can have a baby, her body changes every month—before, during, and after the time of her monthly bleeding. The parts of the body where many of these changes happen are the vagina, womb, ovaries, fallopian tubes, and the breasts, also called the reproductive system. Many of the changes are caused by special chemicals called hormones.
