Preimplantation genetic diagnosis (PGD) is a laboratory procedure that is used in conjunction with in vitro fertilization (IVF) to screen for single-gene defects that may cause genetic disorders. It is a specific test offered to patients who are at a high risk of transmitting a known genetic disorder to their child.

If you’re exploring assisted reproduction technology such as in vitro fertilization (IVF), surrogacy, or egg, sperm, or embryo donation, you can have your embryos screened with preimplantation genetic screening (PGS) or preimplantation genetic diagnosis (PGD). PGS and PGD do not diagnose diseases.
Preimplantation genetic diagnosis (PGD) is the genetic testing technique recommended when couples are at risk of transmitting a known genetic abnormality to their children. It is used in conjunction with in vitro fertilization (IVF) to test for a specified genetic disease or diseases. With PGD, embryos without the genetic defect are transferred to the mother's uterus, which reduces the chances of the child having an inherited genetic abnormality.

In general, pregnancy success rates using donor egg are high because the eggs are from women in their 20s. Dr. Jim Toner, a fertility doctor with Atlanta Center for Reproductive Medicine, explains that the use of genetic testing further increases the success rates, even with single embryo transfer.
Dr. Daniel Shapiro, believes that the advances in genetic testing, including the ability to know which disease-causing genes we carry, will become part of our natural conversations in the near future. Dr. Shapiro is Medical Director of Reproductive Biology Associates in Atlanta, GA, and Clinical Director of My Egg Bank, N.A.
