What does embryo transfer mean?

Embryo transfer is a medical technique that transfers an embryo that has developed to a certain stage after in vitro fertilization into a female uterus so that it can continue to develop into a fetus.

The purpose is to help infertile couples become pregnant and improve the chance and success rate of conception. However, this process involves ethical and legal issues and needs to be carried out under the guidance of a professional doctor. Embryo transfer is usually carried out on the third day (8-cell stage) or the fifth day (blastocyst stage) of embryo development. At this time, there is a implantation window in the uterus, which is conducive to embryo implantation and pregnancy formation. Transplants are usually performed in an outpatient setting and do not require anesthesia, but doctors may give mild sedatives to patients who are stressed.
