What Is PGD (Pre-Implantation Genetic Diagnosis)?
At CSP, we have been working to build strong families since 1980. Part of this mission is to offer information that will help to ensure you have a strong and healthy baby during and after surrogacy. One of the ways that we do this is by letting our intended parents know about pre-implantation genetic diagnosis (PGD). PGD allows people who carry inheritable genetic disorders to avoid passing on those disorders to their children.
How Does PGD Work?
PGD works by isolating the specific gene or chromosome in the embryo that may carry the genetic disorder. This is done after the egg has been harvested and fertilized. The embryo will be grown in a lab for several days until it is able to be tested for the genetic disorder. After testing has occurred and results are in, a healthy embryo will be implanted into the surrogate and allowed to grow and develop. Other healthy embryos can be frozen for use at a later time. Affected embryos are allowed to perish or are used for research with consent from the patients.
Why Get PGD?
PGD is generally used by people who have serious and even life-threatening genetic disorders in their family. Your doctor may advise PGD if you have terminated previous pregnancies because of genetic disorders or have had other children with serious genetic disorders. Be aware that PGD is not always 100% effective at predicting a healthy fetus and child, but it can help significantly reduce the risk of having a child with a serious genetic disorder.
