When preparing to undergo IVF treatments, your fertility specialist will talk about preimplantation genetic diagnosis (PGD), a procedure used before implantation of the embryo. It assists in identifying various genetic defects within embryos created through IVF.

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.
The procedure is done mainly to avoid transferring the affected embryo into the uterus and thus eliminating the need to make the tough decision to use selective termination to avoid an affected child.
