PGT-A – Preimplantation Genetic Testing for Aneuploidy
At Monash IVF, we’re relentless in our mission to help you have a baby. That’s why discussion of embryo screening is always a vital part of your fertility consult. Screening for chromosome changes which occur at conception – usually due to an extra or a missing chromosome being present in an egg or sperm – can help reduce the time taken to achieve a live birth.
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 and increased chance of miscarriage 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.
