GRADE CLASSIFICATION METHOD FOR EVALUATING IN-VITRO FERTILIZATION TREATMENT EMBRYO ACCORDING TO CLEAVAGE BEHAVIORS

摘要

Disclosed is a grade classification method for evaluating an in-vitro fertilization treatment embryo according to cleavage behaviors. In the present invention, in a case in which a human embryo cell is interfered and not damaged, data of dynamic observation on a human embryo is obtained by using a time-lapse imaging technology, and abnormal cleavage behaviors of the human cleavage-stage embryo of in-vitro fertilization are collected and described in detail and are divided into 7 types. The qualitative embryo grade classification method with little subjectivity is established according to the degree of severity of abnormal cleavage, the blastomere range affected by the abnormal cleavage behaviors and the occurrence period of the abnormal cleavage behaviors. The method can effectively screen out a cleavage-stage embryo with optimal blastocyst development potential.
