Myth: Conception occurs in the uterus.

Conception actually occurs in the outer third of the fallopian tubes, and not in the uterus, as many people think. The reason for this is that an egg can only live 12-24 hours, so by the time 24 hours have passed, the egg has only traveled as far as the outer third of the tubes. Implantation on the other hand, does occur in the uterus.
