Purpose:
To evaluate the effects of atosiban on clinical outcomes in patients undergoing frozen-thawed embryo transfer.
Methods:
The clinical data of 1093 infertile patients who underwent frozen-thawed embryo transfer in our center from January 2019 to December 2020 were retrospectively analyzed (control, 418; atosiban, 675). Propensity score matching (PSM) analysis identified 400 matched pairs of patients. The implantation rate, clinical pregnancy rate, live birth rate, biochemical pregnancy rate, abortion rate, multiple pregnancy rate, and ectopic pregnancy rate between the two groups were compared.
Results:
Before PSM, patients differed by infertility factors, number of transferred embryos, and endometrial preparation protocol (P < 0.05). After PSM, characteristics were similar in corresponding patients of the atosiban and control groups. After propensity score matching, we found that there was no significant difference in the implantation rate, clinical pregnancy rate, live birth rate, biochemical pregnancy rate, abortion rate, multiple pregnancy rate, and ectopic pregnancy rate in atosiban and control group (P > 0.05).
Conclusion:
Atosiban did not improve the clinical outcomes of infertile patients with frozen-thawed embryo transfer.
