Preimplantation genetic diagnosis (PGD), as a new assisted reproductive technology which can select normal embryos for transplantation combined with in-vitro fertilization and embryo transfer(IVF-ET)through the analysis of genetic materials before embryo implantation, holds a more and more important position in the diagnosis of genetic diseases and has made an important significance to the Aristogenics.PGD is an important aspect of assisted reproduction technology(ART)with its rapid development. Continuous appearances and comprehensive applications of new methods and technologies have greatly developed the PGD. In this review, we introduce some new methods and their principles about the new research advances of PGD.
