家畜囊胚质量评价指标的研究进展与前沿探索OA

The evaluation of blastocyst quality is of great significance for assisted reproductive technology(ART).Through quality assessment,blastocysts with the highest implantation potential can be selected,reducing the number of embryo transfers and improving the clinical pregnancy rate.However,there are many methods for blastocyst quality evaluation,but there is a lack of horizontal and systematic comparison.At present,the existing blastocyst quality evaluation methods mainly include morphological evaluation,metabolomics,time-lapse monitoring technology,genetic screening technology,artificial intelligence technology,etc.This paper systematically describes and compares the most effective and widely used methods for evaluating the quality of blastocysts at the blastocyst stage by summarizing the existing research systems and comprehensively discussing the advantages and limitations of various blastocyst quality evaluation technologies.Meanwhile,optimization schemes are proposed according to the limitations of various methods.It provides a theoretical basis and technical support for further optimizing the blastocyst quality evaluation technology,improving the clinical pregnancy rate and enhancing the efficiency of embryo selection.
