Human+Reproduction

=__Human Reproduction__ = Humans reproduce __sexually__ and __internal fertilization__ takes place. Both sexes in humans have a set of gonads where gametes are produced. They have ducts for delivery of gonads and structures for copulation.  Women go through the __ovarian  __  and  __menstrual  __  cycles in order to prepare the body for a potential  __zygote  __  (fertilized egg). <span style="background-color: rgb(255,0,119);"><span style="background-color: rgb(255,255,255);">If a sperm does not fertilize an egg (which happens most of the time), a women goes through the menstrual cycle. <span style="background-color: rgb(255,0,119);"><span style="background-color: rgb(255,255,255);">When a woman runs out of eggs __<span style="background-color: rgb(255,0,119);"><span style="background-color: rgb(255,255,255);">menopause  __ <span style="background-color: rgb(255,0,119);"><span style="background-color: rgb(255,255,255);"> occurs. <span style="background-color: rgb(255,0,119);"><span style="background-color: rgb(255,255,255);">Find out more about a women's reproduction, go through this [|tutorial].

** The Journey of the Sperm ** When a pair of humans are ready to reproduce, nessessary steps must be taken. The woman's body needs to be fully developed and the man should have healty sprem. When fertilization occurs, millions of sperm enter the women's vagina through the cervix. The sperm race to a potential egg in the fallopian tubes. But it is a long and strenous journey. Lucky sperm arrives at the egg and pushes through the eggs membrane. This is a zygote!
