Abstract: In vitro fertilization and embryotransfer (IVF-ET) is an useful way to study mechanism of reproduction,for instance,the regulation of oocytematuration,the role of maturation and development of fertilized eggs,embryo implantation as well as a genetic disease model for human.The technology is also helpful for conservation endangered species in nonhuman primates and enhance the quality for laboratory primates.This paper was summarized the progress of IVF-ET in nonhuman primates including oocytes got from hyperstimulation and unstimulated animals,semen collection,semen cryopreservation,fertilization in vitro,embryo transfer and embryo cryopreservation.
