If you are going through IVF, one of the many choices you will be faced with is the decision to send your embryos to undergo genetic testing to evaluate their genetic status before transfer.

There are two main types of genetic testing, known as PGT-A and PGT-M testing.

PGT-A, formerly known as PGS testing, stands for “Preimplantation Genetic Testing for Aneuploidy”. This test identifies embryos affected by chromosomal abnormalities that may affect an embryo. PGT-A will provide information about full aneuploidies (complete extra or missing chromosomes) or partial aneuploidies (extra or missing pieces of chromosomes).

PGT-M testing stands for “Preimplantation Genetic Testing for Monogenic Disorders”, and tests for the presence or absence of a specific genetic difference (“mutation”) that runs in the family. Possible candidates for PGT-M testing include: carriers of sex-linked genetic disorders, single gene defects, or those with chromosomal disorders.

There are several factors to consider in your decision to send your embryos for PGT-A and PGT-M testing – such as the cost ($3500 or more), how many blastocysts you have available to test, if you have a history of previously unsuccessful IVF cycles, what your risk tolerance is, and more.
