What is preimplantation genetic testing?

Preimplantation genetic testing (PGT) is a screening test that can be performed on embryos created via in vitro fertilization (IVF) prior to transfer into the uterus.

Why is PGT helpful? 

One of the most common reasons that an embryo transfer does not result in a pregnancy is due to abnormal embryo genetics. PGT can ensure that the embryo selected for transfer has the correct number of chromosomes, thereby reducing the chances for a failed IVF cycle or miscarriage.

Who are good candidates for PGT?

• People over age 37 (due to higher risk of abnormal embryo genetics with normal reproductive aging)
• Couples who are at risk of having a child affected with an inherited genetic disease
• People with a history of recurrent miscarriages due to chromosomal abnormalities

How is PGT performed?

IVF is a requirement in order to obtain embryos for PGT. When the embryo reaches the blastocyst stage, a few of the cells on the outside of the embryo are biopsied and sent for testing.
