Study Summary
The trial objective is to determine whether the deferred transfer of embryos following cryopreservation at the blastocyst stage following pre-implantation genetic screening (PGS-FET) improves live birthrates compared to both the deferred transfer of cryopreserved embryos without PGS (FET) and immediate transfer at the conclusion of a "fresh" in vitro fertilization (IVF) cycle (Fresh). Additionally, whether "freeze-only" (FET) improves live birth rates compared to "fresh" will be determined.
Primary Outcome
The number of subjects who deliver a live born infant which will be calculated into a live born delivery rate.
Interventions
- PROCEDURE Trophectoderm biopsy
- PROCEDURE Cryopreservation
- PROCEDURE Embryo Transfer
