This study compared the clinical outcomes of the frozen-thawed cycles of high-quality cleavage embryos with low-quality blastocysts to provide a reference for the choice of frozen-thawed embryo transfer schemes and to improve clinical pregnancy rates. A retrospective analysis was performed on the clinical data of patients undergoing frozen-thawed embryo transfer at the Reproductive Medicine Center of Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology from 2016 to 2017. In total, 845 cases were divided into a high-quality cleavage embryo group (group A) and a low-quality blastocyst group (group B). Each group was further divided into subgroups based on the number of transplants. Group A was categorized into two subgroups comprising of 94 cases in subgroup A1 (1 high-quality 8-cell group) and 201 cases in subgroup A2 (2 high-quality 8-cell group). Group B was divided into four subgroups consisting of 73 cases in subgroup B1 (D53BC group), 65 cases in subgroup B2 (D54BC group), 110 cases in subgroup B3 (D63BC group), and 282 cases in subgroup B4 (D64BC group). The pregnancy outcomes and neonatal outcomes between the groups were compared. The clinical pregnancy rates (56.72% and 60.00%) and live birth rates (47.76% and 46.15%) in subgroups A2 and B2 showed no significant differences, but these rates were significantly higher in subgroups A2 and B2 than in the rest subgroups (P<0.05). The multiple birth rate (26.32%) in the subgroup A2 was significantly higher than that in the rest subgroups (P<0.05). There were no statistically significant differences in the abortion rates among all groups (P>0.05). In terms of neonatal outcomes, there were no statistically significant differences in the proportion of premature births, sex ratios, and birth defects among the low-weight and gigantic infants (P>0.05). Transplanting two high-quality cleavage embryos during the frozen-thawed embryo transfer cycles could significantly increase clinical pregnancy rates and live birth rates, but at the same time, it also increased the risks of multiple births and complications to mothers and infants. The D54BC subgroup had the most significant advantages among all groups (P<0.05). The rest low-quality blastocysts had clinical outcomes similar to the single high-quality cleavage embryo group.
