Both ovaries contain about 1 million follicles at birth. A follicle is a hollow ball of cells with an immature egg in the center. About 300 to 500 follicles will develop into mature eggs during the reproductive years.
Each month during the reproductive years, hormones created by the body help the follicles mature. Although 10 to 20 follicles begin to mature each month, usually only one develops fully and releases an egg. This process is called ovulation and occurs each month in a normal female cycle. This happens about 14 days after a woman's period begins.
During ovulation, the ovary can be tender. Some women feel a twinge or cramp in the lower abdomen or back. Sometimes a small amount of extra vaginal discharge may appear. Women can learn to feel and use these symptoms as part of natural family planning methods.
The fertile period is when pregnancy is most likely to occur. It is the time just before, during, and after ovulation. If the egg meets the sperm and becomes fertilized, a pregnancy will result. Each month the woman's cycle begins again to make a new egg.
A woman can ovulate and get pregnant after her very first period. She may become pregnant with her first sexual experience. Birth control and family planning are important to consider, no matter what age a woman is.
