Test tube baby means a child that is conceived outside a woman’s body. These babies are being conceived in a laboratory through the scientific process of In-Vitro Fertilization. In this process, the woman’s egg is processed with a man’s sperm in the lab until it turns into an embryo. The embryo enters the womb through the vagina, and when any of the embryos get stuck to the lining of the womb, you can get a successful pregnancy through “test-tube baby treatment.”
