Incidence of multinucleation and cleavage anomalies. Graph depicts incidence of multinucleation and cleavage anomalies amongst the study group of 648 embryos. Y axis value represents the percent of embryos observed to have each of these anomalies. The diagram also shows how these features affected subsequent embryo development and the ultimate disposition of the embryo. Embryos developing to good quality blastocysts were either frozen or transferred.
