What is PGT-A testing?

Preimplantation Genetic Testing for Aneuploidies (PGT-A)

PGT-A is a genetic test performed on cells taken from embryos produced through IVF.

PGT-A can give information about the genetic health of your embryo to help your care team select an embryo for transfer, helping to improve your chances of achieving a successful pregnancy.

Chromosomes are structures made of protein and DNA that carry genetic information from the sperm and egg to the embryo. A chromosomally normal, or euploid, embryo contains 23 pairs of chromosomes amounting to 46 in total.

One pair of chromosomes comes from the egg and the other the sperm. When an embryo doesn’t have the correct number of chromosomes it is called aneuploid. 

A euploid embryo is much more likely to result in successful implantation and the birth of a baby.

How the PGT-A process works



Several cells are collected from your embryo while it remains in the care of your IVF center



The cells from your embryo undergo analysis at one of our PGT-A testing laboratories



A PGT-A report is sent to your clinician



Based on the PGT-A report results your clinician will help guide your transfer decision

Is PGT-A testing for me?

PGT-A can benefit many IVF patients. Research has shown PGT-A can:

PGT-A 10
PGT-A 12
PGT-A 14

” We wanted to have the best chance to avoid transferring embryos that could lead to miscarriage or severe birth defects. Each failed transfer would have had a significant financial impact. “

What does the PGT-A data tell us?

The number of euploid embryos decreases with age

All patients are at risk of producing aneuploid embryos. As women age, the potential for aneuploid embryos increases. PGT-A can help all families increase their chances of a successful pregnancy.

A retrospective study that investigated 2,464 IVF cycles showed PGT-A significantly improves the live birth rate for patients of all ages.³

Live births are increased across all age groups with PGT-A versus non-PGT-A users.

How is our PGT-A test different?

CooperSurgical® uses artificial intelligence (PGTai® Platform) to analyze your embryo data

How our test works

Our artificial intelligence platform is based on thousands of embryos that resulted in healthy live births. This means the chromosomal status of your embryo is checked against the data taken from these embryos, improving the accuracy of our test.

How PGTai® Platform benefits you compared to other PGT-A technology

  • Has been shown to increase ongoing pregnancy and live birth rates2
  • Biochemical pregnancy loss rates and spontaneous abortion reduced2
  • More euploid embryos available for transfer4
PGT-A 18

Improving patient outcomes

PGTai® Platform significantly increases ongoing pregnancy and live birth rates.
A study investigated outcomes from almost 25,000 IVF embryos using our PGTai technology compared to standard technology (without AI).2

” We chose to have PGT-A testing with CooperSurgical to find out more about our embryos and to be able to make a better decision with all the information possible “
