When working with your doctor to make sure you’re both doing everything you can to have the best chances of success with IVF, you may be recommended PGT as a part of your IVF cycle.
These abnormalities in an embryo could be due to genetic diseases passed down from parent to child, or could be random mutations in an egg or sperm. PGT testing is done at the blastocyst stage, about day 5 of an embryo’s development after an egg has been fertilized in the lab.
Your fertility doctor gently takes just a few cells from the embryo (a harmless procedure to the embryo) and then tests their DNA to determine if there are any signs of abnormalities.
There are three types of PGT tests that your doctor may perform. These are PGT-A, PGT-SR, and PGT-M.
This could be passed down from the parents directly or through recessive conditions and may result in diseases like Huntington’s disease or cystic fibrosis.

This could be passed down from the parents directly or through recessive conditions and may result in diseases like Huntington’s disease or cystic fibrosis.
PGT-A looks for random abnormalities resulting in sudden mutations or poor egg or sperm quality. These have nothing to do with family history and are typically the abnormalities that result in conditions like Down’s syndrome or could result in the embryo not surviving.
PGT-SR looks for chromosomal abnormalities that are hereditary, meaning that they would be inherited from parents. These two tests can be done at the same time.
PGT-M is a separate test designed to find specific genetic changes that are usually the result of a single genes mutation.
If a parent or donor is known to have a mutation associated with hereditary cancer syndrome, already has a child with a single gene disorder, carries an X-linked condition, or has an autosomal dominant condition, doctors usually recommend this test to ensure a successful pregnancy.
It has been shown that PGT can help increase the success rate of IVF in infertile couples and women over 35 who have had trouble getting or staying pregnant.
