What is PGT-M?

For people who know they are at increased risk of passing on a specific genetic condition, PGT-M, or preimplantation genetic testing for monogenic/single gene defects, can be performed prior to pregnancy to greatly reduce the risk of having an affected child.

PGT-M for single gene disorders involves testing embryos created through in vitro fertilization (IVF) and then transferring unaffected embryos. PGT-M was formerly known as PGD, preimplantation genetic diagnosis.
