Comparing Pregnancy Outcomes in Good Prognosis Patients Between Fresh and 'Freeze-All' Single Blastocyst Transfers
NCT02712840 · Status: TERMINATED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 1
Last updated 2018-03-29
Summary
The purpose of this study is to determine whether the chances of becoming pregnant are better when day the single best day 5 embryo (blastocyst) resulting from an in vitro fertilization (IVF) cycle is transferred into the uterus immediately, or after freezing the embryo and transferring it into the uterus in a subsequent cycle, separate from the ovarian stimulation used in the IVF cycle. The investigators hypothesize that in good-prognosis patients, vitrified-warmed elective single embryo transfer will result in higher implantation, clinical and on-going pregnancy and live birth rates than fresh elective single embryo transfer at the blastocyst stage.
Conditions
Interventions
- PROCEDURE
-
Freeze-All Protocol
All good morphologic quality blastocysts are vitrified on day 5 or 6. The best quality vitrified blastocyst frozen on day 5 will be warmed and transferred in a subsequent cycle.
- PROCEDURE
-
Fresh Protocol
Participants receive fresh embryo transfer of best morphologic quality blastocyst on day 5 and vitrification of all good quality supernumerary blastocysts.
