Objetive: Identify different blastocyst classification systems that are used by embryologists in Latin American countries and evaluate the possibility of establishing a consensus among these countries. Methods: An email survey was conducted through the Latin American Network of Assisted Reproduction (REDLARA) aimed at embryologists of assisted reproduction centers in Latin countries. Results: Sixty surveys were collected from 12 Latin American countries, of which 66.7% had > 10 years of professional practice as embryologists. Seven different blastocyst classification systems were reported, of which 5 have previously been described in the literature. Conclusion: Although the group of embryologists surveyed use different blastocyst classification systems, the majority of this group considers that the embryo score system should be unified in their countries as well as in the region.
