Abstract:

Objective: To investigate the effects of atosiban on the pregnancy outcome of frozen-thawed embryo transfer in patients with repeated implantation failure with different etiologies. Methods: From January 2019 to January 2021, the patients diagnosed with repeated implantation failure in their frozen-thawed embryo transfer cycles were selected, and the clinical data of 230 patients were included by the propensity score matching method. Patients were divided into the atosiban group and the control group, according to whether atosiban was used on the day of embryo transfer. A small dose of 6.75 mg (0.9 mL) of atosiban was injected intravenously 30 minutes before embryo transfer in the atosiban group (n=115), while the control group (n=115) did not use. The implantation rate, clinical pregnancy rate, ectopic pregnancy rate, miscarriage rate, preterm birth rate and live birth rate were compared between the two groups. The different causes of repeated implantation failure (endometriosis, immunological or coagulation abnormalities, unknown causes, complex factors and other factors) were analyzed in subgroups, and the differences of clinical outcomes between the two groups were compared. Results: No significant differences were found in the implantation rate, clinical pregnancy rate, ectopic pregnancy rate, miscarriage rate, preterm birth rate and live birth rate between the two groups (both P>0.05). Multivariate analysis showed that there was a significant correlation between the type of transferred embryos and the live birth rate(P=0.001). The subgroup analysis of the different causes of repeated implantation failure showed that in the subgroup of endometriosis, the use of atosiban could significantly reduce the miscarriage rate (P=0.036), but does not increase the live birth rate (P=0.757). Conclusions: The use of atosiban cannot improve the clinical outcome of frozen-thawed embryo transfer cycle in patients with repeated implantation failure, and does not improve the live birth rate. It is not recommended to use atosiban without clinical indications.
