Time-lapse imaging cleavage stage parameters do not enhance selection among traditionally selected high quality euploid blastocysts that implant

      Class I data demonstrate that selection of euploid blastocysts results in enhanced implantation and delivery rates, approaching 60% for single embryo transfers. While reassuring, there are a substantial number of “optimally selected” embryos which fail to implant. Time-lapse imaging parameters through day 3 of development correlate with blastulation rate, but do these same parameters extend to selection between euploid blastocysts? The purpose of this study is to determine if time lapse imaging can provide meaningful data which might aid in distinguishing euploid blastocysts which will implant and progress to delivery from those destined to fail.
