    Prediction of embryo implantation potential by morphology assessment
    Computer Research and Modeling, 2010, v. 2, no. 1, pp. 111-116

    The early embryos developing in vitro to the blastocyst stage have low implantation potential. In the current work the microinjection was used to evaluate the most viable blastocysts with high implantation ability on the basis of morphology changing. The recovery rate of the embryo volume allows assessing the functional activity of trophoblast cells that involved in implantation. The predictive model is suggested to forecast the development effectiveness of blastocysts in vitro. It’s shown the recovery rate of the blastocyst volume after microinjection is the most important feature of implantation potential of early embryos. The maximal recovery rate of blastocyst volume (35.7 % of initial volume per 1 h) correlates with the embryos ability to generate the colonies 72 h after microinjection. By the area under receiver operator curve (AUC) it was shown that combination of such characteristics as blastocyst stage (middle and late) and recovery rate after microinjection allowed to predict the blastocyst development.
