Test Tube baby treatment or IVF treatment is done for couples who do not conceive by the natural method. In a natural pregnancy and in IUI, the fertilization of the egg and sperm happens inside woman’s body. In IVF/ ICSI, the fertilization is done outside the body – in the ART laboratory. The term “test-tube baby,” prior to the development of in vitro fertilization technologies in the twentieth century, was used to refer to babies born as a result of artificial insemination. Since all these procedures assist reproduction, they are called as Assisted Reproductive Techniques (ART).Embryos with the correct number of chromosomes (also called euploid embryos or genetically normal embryos) have a better chance of leading to a successful pregnancy.
