PGT-A – Preimplantation Genetic Testing for Aneuploidy
One in five of our patients choose to screen their embryos for chromosome changes in order to increase their chance of conception. If you’re undergoing IVF treatment, we recommend you consider preimplantation genetic testing for aneuploidy (PGT-A).
Typical embryonic cells contain 46 chromosomes in 23 pairs – 23 chromosomes from each parent. If the egg or sperm has an extra or missing chromosome, then there is a high chance of miscarriage or failed implantation. This is the main cause of declining fertility with increasing maternal age.
While we perform the genetic testing, your embryos are kept frozen and in storage. When we identify embryos with the highest chance of implantation, they’re transferred individually in a frozen IVF cycle. Your remaining viable embryos stay frozen for future use.
