Abstract: Embryo transfer is not just a simple process of implanting the embryos into the uterus. A successful and effective embryo transfer requires not only high-quality embryos and appropriate uterine environment, but also high technical level of embryo transfer itself. Emphasis on and mastering the embryo transfer techniques will help to increase the success rate of in vitro fertilization-embryo transfer. In this article, the role of embryo transfer techniques and clinical skills in improving pregnancy outcomes was investigated, aiming to provide practical reference for clinical practitioners.
