Abstract:
ObjectiveTo investigate the clinical efficacy of oral dydrogesterone alone for luteal phase support in natural cycle frozen-thawed embryo transfer （NC-FET）. MethodsThe clinical data of 1 530 NC-FET cycles enrolled in our Reproductive Center from January 2019 to September 2021 were retrospectively analyzed. According to different luteal support protocols， the patients were divided into oral dydrogesterone alone （group A， n=524）， vaginal progesterone soft capsules （group B， n=401） and vaginal progesterone soft capsules combined with dydrogesterone （group C， n=605）. The clinical outcomes and cost-effectiveness ratio were compared among the three groups. The primary outcome was live birth rate. ResultsThe live birth rate was 43.13% （226/524） in group A， 39.15% （157/401） in group B， and 42.64% （258/605） in group C. There was no statistical difference among the three groups （P > 0.05）. No statistical difference was observed in the HCG positive rate， implantation rate， biochemical pregnancy rate， clinical pregnancy rate， spontaneous miscarriage rate， ectopic pregnancy rate， twin delivery rate， premature delivery rate and newborn weight among the three groups （P>0.05）. Logistic regression analysis revealed that the three luteal support regimens did not affect live birth rate. Pharmacoeconomic analysis showed that taking group B as a reference， the cost increased by 19 227.30 yuan for every 1% increase in live birth rate in group A. ConclusionsIn NC-FET cycle， oral dydrogesterone alone can achieve the same clinical outcomes as vaginal progesterone soft capsules and vaginal progesterone soft capsules combined with dydrogesterone. Compared with that of progesterone soft capsules， the cost of oral dydrogesterone alone is increased， a large sample and multicenter prospective study is needed to further confirm our results.
