Computer-automated time-lapse microscopy (TLM) results enhance the opportunity to select embryos that blastulate within the window of endometrial receptivity

      The EevaTM Test, a computer automated test enabled by TLM generates a binary result (high or low) that prognosticates which embryos on day 3 are more likely to reach the blastocyst stage of development. However, some embryos grow more slowly, reaching the blastocyst stage on day 6, rather than day 5. It has been shown that slowly blastulating embryos have better outcomes when cryopreserved and transferred during a cycle with synchronous endometrial development than when transferred in a fresh IVF cycle. This study seeks to characterize if this outcome predictor can refine selection by performing a paired analysis to identify which embryos blastulate on day 5 versus day 6.
