PGT — Preimplantation genetic testing

Preimplantation genetic testing (PGT) is an optional add-on to IVF in which embryos are biopsied and tested for genetic or chromosomal abnormalities before being transferred to the uterus. By identifying the healthiest embryos prior to transfer, PGT can improve IVF success rates and reduce the risk of miscarriage. Chelsea Fertility NYC offers PGT as part of a comprehensive IVF treatment plan.

PGT-A (preimplantation genetic testing for aneuploidy), formerly called PGS, screens embryos for abnormal chromosome numbers — such as Down syndrome, Turner syndrome, or other conditions caused by having too many or too few chromosomes. PGD (preimplantation genetic diagnosis) tests for specific inherited single-gene disorders, such as cystic fibrosis, sickle cell disease, or BRCA mutations. Your physician will recommend which type of testing is appropriate based on your medical and family history.

PGT-A is often recommended for women over age 35, patients who have experienced recurrent miscarriage, those with a history of failed IVF cycles, or anyone who wants to maximize the chance of a successful single embryo transfer. PGD is recommended when one or both partners are known carriers of a genetic condition. Chelsea Fertility NYC follows ASRM guidelines when recommending genetic testing and will explain whether it is appropriate for your situation.

PGT-A is considered an elective service and is not covered by insurance — patients pay out of pocket. The cost depends on the number of embryos being tested and will vary per patient. Your care team will explain whether testing is appropriate for your plan and provide a detailed cost estimate before proceeding. See our pricing page for more information.

No — PGT significantly improves the odds of a successful transfer but cannot guarantee a pregnancy or live birth. Even a chromosomally normal embryo may not implant successfully. However, by identifying the most viable embryos before transfer, PGT reduces the likelihood of miscarriage and increases the efficiency of each IVF cycle. Your physician will provide a realistic assessment of what PGT can and cannot offer in your specific case.
