In vitro fertilization (IVF) is a process by which an egg is fertilized by sperm outside the body. The process involves monitoring and stimulating a woman's ovulatory process, removing ovum from the woman's ovaries and letting sperm fertilize them in a liquid in a laboratory. The fertilized egg (zygote) is cultured for 26 days in a growth medium and is then implanted in the same or another woman's uterus, with the intention of establishing a successful pregnancy. The baby produced by IVF is called as test tube baby. The first test tube baby was Louise brown which was born on 25 July 1978.
