Clinical features and reproductive outcomes for embryos undergoing dual freeze-thaw sequences followed by blastocyst transfer: critique of 14 consecutive cases in IVF.
These data suggest that the physiologic stress associated with two consecutive freeze-thaw processes is likely minor. Dual freeze-thaw of embryos does not appear to adversely impact delivery rate in IVF; a livebirth delivery rate of 35.7% per transfer was observed in our population.
