It releases unused eggs from the body every time a girl gets her cycle. During this time it is most likely impossible to get pregnant if the girl had chosen to have sex wether or it was protected. It is also part of maturity for a woman when she gets her cycle.

The menstrual cycle is the production of, then maintenence of, then finally expulsion of a female's egg from her uterus. The fluid and matter consists of blood, & soft tissue from uterus wall, plus the egg.

The menstrual cycle is simply to allow the female to become fertile for reproduction. Then to remove an unfertilized egg.

It is not a means of contraception
