In general, most (if not all) embryos that fertilize will reach this stage. The greatest attrition rate comes from day 3 to day 5-6, or the blastocyst stage. A blastocyst is the final stage of the embryo before we cryopreserve them or transfer to a patient.

Are day 6 blastocysts good?

We demonstrated that the blastocysts vitrified on day 6 were of higher quality compared to the blastocyst vitrified on day 5 but still resulted with a significantly lower pregnancy rate. This study is the first to evaluate the pregnancy outcome after transfer of vitrified slow-growing good quality embryos.

What percentage of fertilized eggs fail to develop?
