Genetic testing IVF embryos doesn’t improve the chance of a baby

If you’re going through IVF, you may be offered a test to look at your embryos’ chromosomes.

Pre-implantation genetic testing for aneuploidy (chromosome abnormalities), known as PGT-A, is an “add on” used to help choose embryos with the right number of chromosomes. It’s promoted by IVF clinics as a way to increase the chance of success, especially for women over 35.

But the evidence shows that in most cases, PGT-A doesn’t improve the chance of a baby.
