PGD – Preimplantation Genetic Diagnosis

We offer Preimplantation Genetic Diagnosis (PGD) to patients at risk for genetic diseases.  Using PGD, embryos suspected of genetic abnormalities are examined prior to transfer and only normal embryos are placed into the uterus. PDG is performed as a part of an IVF Cycle.

PGD helps reduce the incidence of genetic disease in some couples. Many genetic diseases are sex-linked meaning they can only be transferred to a child of a particular gender.

Once PGD preparations are completed (about 2 months), patients start an IVF cycle. After the eggs are fertilized in the lab and developed into embryos, our specially trained embryologists will remove a single cell from each viable embryo (embryo biopsy). After further processing by our skilled staff, all the biopsied cells will be shipped to the genetics lab for testing.

Once the PGD results are obtained, we choose healthy embryos which are transferred into the uterus. Unused, normal embryos may be frozen for future use.

Preimplantation Genetic Screening (PGS)

Chromosomal abnormalities are responsible for a substantial proportion of early pregnancy losses and increase with maternal age. Egg quality is considered to be the major cause of reduced implantation rates, and therefore viable pregnancy rates.

Preimplantation Genetic Screening (PGS) involves testing individual cells removed from embryos before their replacement back into the uterus, with the intention of selecting normal embryos.


You may be a candidate for PGD if:
  • You and/or your partner are carriers of an abnormal gene.
  • You and/or your partner have a chromosome abnormality. (such as translocation)
  • Other members of your family carry an abnormal gene.
You may be a candidate for PGS if:
  • You are an IVF patient 35 years or older.
  • Have had two or more miscarriages.
  • Have failed at least twice to conceive through IVF.

If you think you might be a candidate for PGD or PGS, please call 516-562-BABY (2229) or request an appointment.
