What is preimplantation genetic diagnosis (PGD)?

Preimplantation genetic diagnosis (PGD) only applies to pregnancies achieved through assisted reproduction or IVF.

When the embryos are formed, cells from the embryo are extracted and tested to determine whether they contain any abnormal genetic material that can potentially be passed on to the baby. Thalassemia, a blood disorder, and cystic fibrosis are two  such conditions.
