Abstract: Disclosed in the present invention is a non-invasive detection method for screening for a well-developed blastocyst. A DNA methylation profile of a few of trophectoderm cells in a blastocyst is detected, and the average methylation level and the methylation pattern of embryos identified as having a good morphology in Gardner morphological blastocyst grading process are used as the standard for screening for well-developed blastocysts.

Furthermore, results of methylation sequencing may be analyzed to determine whether a chromosome is abnormal, so as to directly exclude chromosome-abnormal embryos.
