Couples who have a genetic condition, older mothers, and anyone who wants the best chance for a healthy baby can take advantage of genetic testing performed during in vitro fertilization. Our team at The New York Fertility Center has extensive experience performing PGD and PGS, two procedures that detect genetic disorders and chromosomal abnormalities in embryos before they’re transferred into the uterus. To learn more about PGD and PGS, call one of the offices in Manhattan or Flushing, New York, or use online booking to schedule a consultation.
request an appointmentWhat are PGD and PGS?
Preimplantation genetic diagnosis (PGD) and preimplantation genetic screening (PGS) are two types of genetic testing available for couples undergoing in vitro fertilization (IVF).
PGD: Tests for single gene disorders that one or both parents are known to carry
PGS: Screens for chromosomal abnormalities, such as Down Syndrome
What are the benefits of PGD and PGS?
PGS detects congenital disabilities and chromosomal imbalances that contribute to the primary causes of unsuccessful IVF: implantation failure and spontaneous miscarriage. Another benefit gained from PGD and PGS is that it allows our team at NYFC to transfer a single, healthy embryo to your uterus.
The practice guidelines for IVF recommend implanting more than one unscreened embryo. While this increases the success rate of IVF, it also raises your risk of carrying multiples. Your chance of effective IVF is the same when PGD and PGS screening identify one healthy embryo.
Who should consider PGD and PGS?
The risk of having a baby with a chromosomal imbalance increases with the mother’s age, so our team at NYFC may recommend PGS for older women.
If you have recurrent miscarriages, you may also benefit from PGS. About half of all miscarriages are caused by chromosomal abnormalities, which can be identified with PGS.
You may want to consider PGD if you or your partner have a known genetic condition. A few examples of heritable disorders that commonly prompt PGD testing include:
- Huntington’s disease: progressive deterioration of nerves in the brain
- Cystic fibrosis: damages lungs and digestive system
- Hemophilia: impaired blood clotting
- BRCA syndrome: breast and ovarian cancers
- Lynch syndrome: colon, ovary, uterine, stomach, skin, and other cancers
- Duchenne muscular dystrophy: progressive muscle weakness
- Marfan syndrome: affects the function of connective tissues
- Tay-Sachs disease: destroys nerve cells in the brain and spinal cord
How are PGD and PGS performed?
Our team at NYFC waits about five days after your eggs are successfully fertilized in the lab. By then, each embryo has about 100 cells, so our team can safely remove several cells.
These cells are tested for genetic disorders and chromosomal abnormalities. When the results of your genetic testing are ready, you and our team at NYFC can make decisions about which embryo to transfer.
