In vitro fertilisation (IVF) is an option for women to produce their own child who cannot reproduce naturally. During in vitro fertilisation (IVF):

1.Doctors collect freshly released egg and sperm
2.Egg and sperm are allowed to fertilise by keeping them together under laboratory conditions for few hours.
3.Fertilisation occurs and the zygote is allowed to develop for about a week.
4.The one week grown zygote is implanted in the mother’s uterus.

Complete development takes place in the mother's uterus and the baby is born like any other baby. Babies born through this technique are called test-tube babies.
