WHAT IS A "TEST TUBE BABY" ?
A baby developed from an egg that was fertilized outside the body and then implanted in the uterus of the biological or surrogate mother. Test tube bay means production of babies in a test tube. But in practice test tube baby means artificial fertilization of egg and sperm outside the body and implantation of the zygote into the womb of the mother. So far no one has succeeded in growing a human embryo completely into a child on culture media.Test tube bay production involves two main steps - in vitro fertilization (IVF) and embryo transfer (ET). Historically the first attempt to produce the test tube baby was by an Ital­ian scientist Petrucci (1959). In his experiment he removed an ovum from a patient and put it in the middle of spermatozoa in a glass dome. One of the sperms fertilized the egg and a small embryo formed, but this survived only for 29 days.
