Pre-Implantation Genetic Diagnosis

Pre-implantation Genetic Diagnosis (PGD) is a technology which allows genetic testing of an embryo prior to implantation and before pregnancy occurs. It is used in conjunction with IVF and allows only those embryos diagnosed as being free of a specific genetic disorder to be transferred into a woman for pregnancy.
