CARE Fertility Group presented the following Poster “Can blastocyst percentage of re-expansion after warming be used to predict implantation potential and live birth outcome?” at the Fertility Conference in Edinburgh from January 9th to 11th 2020.
Thanks to the successful embryo development in in vitro culture, the number of blastocysts vitrified worldwide has increased greatly. Previous studies already defined generally high blastocyst cryo-survival rates after vitrification-warming (>95%), along with a positive correlation between blastocyst re-expansion and morphology with implantation. This study has demonstrated that blastocyst’s percentage of re-expansion post-warming significantly correlates with implantation and also live birth outcomes.
