Preimplantation Genetic Diagnosis

Preimplantation genetic diagnosis (PGD) is a genetic testing procedure performed on embryos created with in-vitro fertilization by examining an embryo for a specific genetic mutation known to cause serious disease. It enables people with an inheritable condition in their family to avoid passing it on to their children.

Who should consider PGD?

PGD avoids pregnancy termination as it allows selection of an embryo free of the genetic disease at issue before pregnancy is established. PGD is available for almost any inherited condition for which the exact mutation is known. PGD is best suited for:

  1. Individuals with known single gene disorder, e.g. cystic fibrosis, cystic disease, Tay Sachs disease,
  2. Individuals with a chromosomal rearrangement, e.g. chromosomal translocation in which a segment of a chromosome is found at a location other than its normal place,
  3. Couple with a child known to have a genetic mutation, or
  4. Couples who desire to match stem cells when a family member is in need of a tissue donor.


At Dr. Sunita’s IVF we strongly encourage all patients who are interested in PGT to have an appointment with our genetic counselor. This consultation will ensure you fully understand the risks, benefits, and limitations of this testing.  The genetic counselor will also determine if there are any additional concerns based on your personal and family history that should be addressed prior to your IVF cycle.
