PGS, or preimplantation genetic screening, is a genetic test performed on embryos produced through IVF. PGS gives information about embryos’ genetic health to help your care team select the best embryo for transfer and improve your chance of achieving a successful pregnancy.
How PGS Works?
PGS works by looking at the amount of genetic material within IVF embryos. This genetic material is housed within structures called chromosomes. Chromosomes are very important for healthy growth and development.
Embryos with the incorrect number of chromosomes (also called aneuploid embryos) typically do not result in a successful pregnancy or may lead to the birth of a child with a genetic condition.
Embryos with the correct number of chromosomes (also called euploid embryos) have a better chance of leading to a successful pregnancy.
PGS identifies embryos with the correct number of chromosomes, so your care team can select the embryo with the best chance of leading to IVF success.
WHO IS PGS FOR?
PGS is appropriate for the vast majority of people undergoing IVF.
All women are at risk of producing chromosomally abnormal embryos. As a woman ages, the potential for chromosomally abnormal embryos significantly increases, regardless of the number of embryos produced.
PGS can help women of all ages increase their chances of a successful pregnancy.
BENEFITS OF PGS
- Higher chance of pregnancy
- Reduced risk of miscarriage
- More confidence in transferring a single embryo, avoiding health risks associated with twin or triplet pregnancies
- Reduced number of IVF cycles needed to achieve pregnancy, potentially reducing the time to pregnancy and the costs of extra cycles
CooperGenomics uses the most advanced embryo screening technology available, providing the most complete picture of chromosomal health.
For each embryo tested, PGS results will fall into one of three categories: euploid, aneuploid, or mosaic. This information can help your care team select the best embryo for transfer.
