The first step in embryo transplantation involves collection of eggs from the female and fertilizing it in a laboratory through a process commonly known as IVF. During this process the best quality embryo is chosen and then transferred to the female’s womb for the pregnancy to be established. This is done in a 3 day old embryo. Depending on the age of the female one or two embryos are placed. Some times a 5 to 6 day old embryo is also transferred for better success. This is called a blastocyst embryo transfer. The transfer involves inserting a speculum into the vagina using ultrasound guidance. The embryos are then passed down through this tube into the womb. Two weeks after the transfer, the female is tested for success of the procedure through a blood test fro pregnancy.
