Preimplantation genetic diagnosis (PGD), also called preimplantation genetic testing for monogenic/single gene defects (PGT-M), is a procedure performed in conjunction with in vitro fertilization (IVF) to test embryos for genetic abnormalities. PGD allows us to test embryos from patients at high risk for genetic disease prior to conception; this significantly increases their chances of having a healthy baby.

Sex-linked diseases

Many genetic diseases are sex-linked, meaning they can only be transferred to a child of a particular gender. Hemophilia is an example of a sex-linked disease that is transferred to male children. In cases where the risk of transferring hemophilia is present, PGD can be used to transfer female embryos only to the uterus, thus eliminating the chance for hemophilia in the child.

Who it’s for

You may be a candidate for PGD if:

  • You or your partner have a genetic disease
  • You and/or your partner are carriers of an abnormal gene
  • You and/or your partner have a chromosome abnormality such as translocation (PGT-SR)
  • Other members of your family carry an abnormal gene
