Pre-implantation Genetic Diagnosis

Pre-implantation genetic diagnosis (PGD) is a technique used to identify a known familial genetic mutation in embryos created through in vitro fertilization (IVF) before transferring them into the uterus. Couples have the option of transferring only those embryos found not to carry the familial mutation for implantation, if they wish. PGD is performed in conjunction with IVF and is offered for both fertile and infertile couples. This New York Times article discusses one family who used this technology because of their family history of Hereditary Non-Polyposis Colorectal Cancer (HNPCC).
