But even though the reproductive system is essential to keeping a species alive, unlike other body systems, it's not essential to keeping an individual alive. These openings are covered externally by two sets of skin folds.

Infants who consumed soy-based formula as newborns had differences in some reproductive-system cells and tissues, compared to those who used cow-milk formula or were breastfed, according to a new study. At this point, if she had intercourse near the time of ovulation, the woman has no idea whether an unfertilized egg or a new is travelling down that tube. They produce, store, and release eggs into the fallopian tubes in the process called ovulation (pronounced: av-yoo-LAY-shun).

In laboratory studies genistein causes abnormal reproductive development and function in rodents, but little is known about its effects on infants. Some women who have had sex don't have much of a change in their hymens, though. This uncommon but life-threatening illness is caused by toxins released into the body during a type of bacterial infection that is more likely to develop if a tampon is left in too long.
