Prognostic factors for delivery in patients undergoing repeated preimplantation genetic aneuploidy screening.
We performed a retrospective analysis of patients who had a first failed preimplantation genetic aneuploidy screening (PGS) cycle. At least one euploid embryo was found in 64% of the patients who had no euploid embryos available on their first PGS cycle. A previous failed treatment because of lack of euploid embryos does not contraindicate a further assisted reproductive cycle.
