Preimplantation Genetic Testing For Aneuploidies (PGT-A)

PGT-A (formerly known as PGS) is a tool used to optimize the efficiency of IVF, increasing the likelihood of a successful pregnancy.

What Is Preimplantation Genetic Testing For Aneuploidies (PGT-A)?

As a woman ages, the chance one of her embryos is aneuploid (abnormal set of chromosomes which affects viability) rises. PGT-A identifies embryos that are euploid (normal set of chromosomes), increasing the chance for a successful pregnancy. PGT-A is included in our IVF For ME™ Program.

Patient Benefits of PGT-A

  • High implantation and pregnancy rates (about 60%) and extremely low miscarriage rates (>10%)
  • Enhanced confidence in single embryo transfer stemming from embryologist identifying chromosomally normal embryos that have the highest chance of implantation
  • Safer IVF stimulation cycles that avoid hyperstimulation syndrome almost 100% of the time
  • Enhanced fetal growth and pregnancy outcome with frozen embryo transfer
  • The ability to identify and freeze healthy embryos for fertility preservation for future pregnancy wishes
  • Provides credible information for patients considering donor egg or embryo adoption in situations where no embryos are chromosomally normal (typical in older patients)
  • IVF with PGT-A (IVF For ME) – Ages 35-37 57.83% 57.83%
  • IVF without PGT-A (Traditional IVF) – Ages 35-37 35.29% 35.29%
  • IVF with PGT-A (IVF For ME) – Ages 38-40 51.26% 51.26%
  • IVF without PGT-A (Traditional IVF) – Ages 38-40 23.81% 23.81%
  • IVF with PGT-A (IVF For ME) – Ages 41-42 66.67% 66.67%
  • IVF without PGT-A (Traditional IVF) – Ages 41-42 (n=3) 0% 0%
  • IVF with PGT-A (IVF For ME) – Ages Over 42 80% 80%
  • IVF without PGT-A (Traditional IVF) – Ages Over 42 (n=2) 50% 50%

These results were achieved with > 95% single embryo transfers.

When To Consider PGT-A

We offer PGT-A to all IVF patients. Those interested in this testing will meet with our Genetic Counselor, Stephanie Hill, to consider whether PGT-A makes sense for them. Common indications for recommending PGT-A include:

  • Maternal age over 34
  • Paternal age over 40
  • Unexplained infertility at any age
  • Prior failed IVF without explanations
  • Prior pregnancy losses
  • Diminished ovarian reserve (i.e. low AMH, high FSH)

She is honest and open. Be open minded and trust in her process. This is a marathon, not a sprint! Dr. McGuirk will be with you the whole way."
