In vitro fertilisation (IVF) as one of the assisted reproductive technologies(ARTs) plays an important role in modern medical treatment of human infertility. The development of ART has not only broken through the natural way and process of human reproduction, but also exerted a great influence on the development of reproductive medicine. Therefore, British scientist Robert Edwards won the Nobel Prize in physiology and medicine in 2010 for the contribution of his research on the assisted reproductive technology.
