Reproductive System, in simpler words

This version comes from Wikijunior, a set of books written for children aged 8 to 11. It is shorter and uses plainer language than the article above.

From Wikijunior: Biology

NOTOC

In humans and many other living things, there are two sexes: men and women. Babies are made when a cell called a sperm (produced by men) comes together with an egg cell or ovum (produced by women) in a process called fertilization. When the cells combine, they form a new cell, called a zygote (zy rhymes with eye; gote sounds like goat) which has all it needs to make a new man or woman. The zygote will make a baby like his mother and father.

Babies come from their mother. To make a baby, the father must put his sperm into the mother’s body. This is called having sex. The man puts his penis into the woman’s vagina and the sperm cells swim into the mother’s body.

Fertilization happens in the mother. The new zygote grows into a ball called a morula which will stick to the mother’s womb. This ball grows into a blastula which later develops into a baby.

Nine months after fertilization, a new baby will come out of the mother’s vagina in a process called childbirth.
