The Use of Preimplantation Genetic Testing For Aneuploidy (PGT-A):

Committee Opinion

Some topics covered in this guidance:

  • Day 5 vs Day 6 biopsy

  • PGT-A with Preimplantation Genetic Testing for Monogenetic Disorders (PGT-M)

  • Thaw/Warm, Biopsy, and Recryopreserve for PGT-A

  • Neonatal and Childhood Outcome

What are some gaps in PGT-A based on this guidance?

  • In general, the value of PGT-A as a universal screening test for all IVF patients has yet to be determined

  • To date, there are very few studies directly comparing the specific laboratory techniques for assessing ploidy. Future studies are warranted to determine if any platforms are superior.
