What is SELECT PGT-A?

SELECT PGT-A is a comprehensive chromosome screening to test embryos for numerical chromosomal abnormalities prior to transfer. All 23 pairs of human chromosomes, including 22 pairs of autosomes and 1 pair of sex chromosomes, are analyzed to evaluate any numerical gains or losses of chromosomes.

For each embryo tested, the results will fall into one of the following 3 categories:

1) Euploid embryo – All cells have the correct number of chromosomes. No abnormalities detected and embryo is suitable for transfer.

2) Aneuploid embryo – All cells have the incorrect number of chromosomes. Embryo is not suitable for transfer. Example of condition: Trisomy

3) Mosaic embryo – Embryo has a mixture of cells with correct and incorrect number of chromosomes. May be considered for transfer if no other euploid embryos are available.

• Increases the chance of pregnancy per embryo transfer
• Decreases chances of miscarriage.
• Minimizes risk of genetic abnormalities in the baby
• Enables confident single embryo transfer, avoiding health complications associated with twin or triplet pregnancies
• May reduce the number of embryo transfers needed to achieve pregnancy, thereby saving time and money.

SELECT PGT-A decreases the time to achieve an ongoing pregnancy.¹

A recent study showed SELECT PGT-A helped decrease the overall cost of having a healthy baby compared to a non SELECT PGT-A cycle.²
