PGT-A, or preimplantation genetic testing for aneuploidies, is the process of screening IVF embryos for chromosome abnormalities prior to transfer, with the goal of increasing the likelihood of achieving a successful pregnancy. PGT-A was formerly known as PGS, preimplantation genetic screening.
PGT-A has been shown to:
- Increase implantation rates
- Reduce miscarriage rates
- Increase ongoing pregnancy rates
- Increase live birth rates
- Reduce the time to pregnancy
