ARTIFICIAL FERTILISATION : TEST TUBE BABY
( I.V.F )
Some women are not able to bear babies because their oviduct are blocked. This prevents the ovum from being fertilized as the sperm cannot reach the oviduct where the ovum is present. This problem can be overcome by fertilizing an ovum with human sperm in the laboratory with a technology called invitro fertilization (I.V.F).
This technique is quite useful when natural fertilisation fails. This technique was first successfully introduced in humans in 1978.
In this technique, the doctor collects freshly released egg and sperm and keeps them together for a few hours for invitro fertilization.
Fertilization occur outside the body of female. The zygote is allowed to develop for about a week. The zygote is then placed into the uterus of the mother. The embryo develops into a baby in about nine months. Baby born through this technique are called test tube babies.
