What is preimplantation genetic testing (PGT)?

PGT involves running multiple tests on each embryo to select the best embryo to transfer before it is placed into the uterus. This may help to increase the chance of a healthy pregnancy by reducing the risk of implanting an embryo with genetic or chromosomal abnormalities. This process can also decrease chances of miscarriage, which is often associated with chromosomal issues in the embryo.

How PGT treatment works

After your embryos grow for 5-6 days in our lab, our embryologists will biopsy your embryos and send the sample to a PGT lab, to run one or more of the following tests:


  • PGT-A (Preimplantation Genetic Testing for Aneuploidy): This chromosomal test will help to decrease the chances of implantation issues or miscarriage, and can help detect chromosomal abnormalities. With this test it’s also possible to determine the sex of the embryo if you carry a genetic risk of sex-linked disease, or for other personal reasons.
  • PGT-M (Preimplantation Genetic Testing for Monogenic Disorders): This genetic test is helpful for couples in which one or both partners are carriers of genetic mutations that could result in the baby having a monogenic disorder.
  • PGT-SR (Preimplantation Genetic Testing for a Structural Rearrangement): This is a test that screens for structural issues in the chromosomes that form an abnormal embryo and will almost always result in miscarriage.

Is PGT right for me?

Whether you should pursue genetic testing is based on a number of factors including your age, genetic background, and medical history. Ultimately, PGT can improve the chances of pregnancy for anyone undergoing IVF. Knowing which embryos may result in miscarriage or abnormal pregnancy gives you more autonomy over your own experience and the health of your family.

You’ve got questions, we’ve got answers.

Embryos with the wrong number of chromosomes usually do not implant, or start to implant but result in a miscarriage. PGT-A identifies the embryos most likely to implant normally so that the transfer of a single embryo is more likely successful. Especially for women over 35 and those with recurrent pregnancy losses, PGT-A allows us to transfer just one healthy embryo with the best chance of pregnancy and the lowest chance of miscarriage.

Current evidence suggests that the biopsy for PGT does not harm the embryo. A very small number of cells are removed from an area that will eventually grow into the placenta. The inner cell mass, which is the part of the embryo that will become the baby, is not touched.

PGT-M may be appropriate when intended parents are at high risk of having a child with a serious genetic disease. If family history or genetic carrier screening suggest high risk, we will refer you to a genetic counselor to discuss next steps.
