PGT-A ensures your embryos are chromosomally normal
A normal human embryo has 23 pairs of chromosomes, or 46 chromosomes in total. Any more or less, and the embryo may have a lower risk of survival and a higher risk of disability. In PGT-A, or preimplantation genetic testing for aneuploidy, embryologists count chromosomes from each IVF embryo. As such, we can transfer only chromosomally normal embryos.
The goal is to prevent the transfer of genetically abnormal embryos. This increases the odds that you will get pregnant, stay pregnant and deliver a healthy baby. We remove a few cells from each embryo created through IVF.
Who needs PGT-A?
When an embryo has extra chromosomes, the baby could have life-threatening developmental problems, intellectual disabilities or physical defects. An example is Trisomy 21, or Down syndrome.
If a chromosome is missing, the condition is known as monosomy. This can result in conditions such as Turner syndrome. Chromosomal structure can also be abnormal in other ways, causing a wide range of issues.
PGT-A can help anyone who is concerned about having a baby with a chromosomal disorder that could affect the child’s quality of life, as well as for any woman older than 30 who is undergoing IVF. Our most recent data shows that in all age groups over 30, pregnancy rates increase with this technique.
With embryo biopsy, there is a slight risk of damage to the embryo, but people who choose PGT-A feel that the benefits far outweigh the risks, as chromosomal abnormalities can result in serious lifelong difficulties for a child. For women and couples who have experienced repeated miscarriages, this test may hold the key to unlock the mystery of their infertility, once and for all.
Because chromosomally normal embryos have a better chance to implant and grow into healthy babies, this technique also makes it possible to achieve excellent pregnancy rates through single embryo transfer, reducing the odds of a high-risk twin or triplet pregnancy.
Proceed with confidence
By using PGT-A to ensure that your physician transfers only chromosomally normal embryos, you can increase your chances of having a healthy baby, while reducing the odds that your pregnancy will end in miscarriage or your child will face lifelong physical, developmental or intellectual limitations.
