Official title
A Prospective, Randomized, Controlled Clinical Trial Evaluating the Superiority of Preimplantation Genetic Screening (PGS) and Deferred Transfer of Cryopreserved Embryos Over "Freeze-Only" Deferred Transfer Without PGS or Immediate Embryo Transfer During a "Fresh" In Vitro Fertilization Cycle
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
