Significance

The reproductive system is not vital to the survival of the individual, but it is vital to the survival of its species. The human reproductive systems are used to mate, procreate, and pass on genes to the next generation. Without the human reproductive system, the human race would die off and live in a dystopia similar to the movie Children of Men.

Journey of an Egg

Ovulation starts around two weeks after the beginning of the follicular phase. During this phase, the egg is released from the ovary into the fallopian tube aided by fimbrae. If fertilized, progesterone prepares uterus for fertilized egg to implant into the walls of the uterus. The women is now pregnant and will give birth to a baby in nine months time. If unfertilized, the egg passes through the uterus and the lining of the uterus breaks down to prepare for the next menstruation cycle.
