Embryo transplantation is a technique used to treat infertility among females. It not only alleviates infertility but also helps avoid genetic disorders. The process involves placing a fertilized embryo into the uterus of a female in order to establish pregnancy. The embryo can be fresh or frozen from a previous menstrual cycle. Usually embryos that are 3 days old are transferred to the uterus using highly precise techniques performed by well trained medical practitioners. The embryo may be transferred to the original mother of the embryo or to another female who would carry the embryo as a surrogate, in case the original mother’s uterus cannot hold the embryo.
