Preimplantation genetic diagnosis
Preimplantation genetic testing is a technique used to identify genetic defects in embryos created through in vitro fertilization (IVF) before pregnancy. Edwards and Gardner successfully performed the first known embryo biopsy on rabbit embryos in 1968. In humans, PGD was developed in the United Kingdom in the mid 1980s as an alternative to current prenatal diagnoses. PGD was developed to allow couples at risk of passing on a serious genetic disease to have children free of the disease. This procedure is most widely used to prevent the birth of children with conditions such as Down's syndrome, Tay-Sachs disease, cystic fibrosis, sickle cell, and Huntington's chorea.
