Abstract：Objective To explore the influencing factors of the pregnancy outcome of the frozen embryo transfer in ar-tificial cycles. Methods A retrospective analysis was performed for clinical data of 930 cases undergoing frozen embryo trans-fer treatment during Jan. 2011 and Dec. 2014. All patients accepted hormone replacement therapy. Endometrial thickness was monitored by transvaginal ultrasound. Estrogen ( E2 ) and progesterone ( P) level as well as E2/P ratio were recorded. Infertil-ity factors, time, age, ovulation induction regimen, insemination, endometrial thickness, E2 level, P level and E2/P ratio and their relation with the clinical pregnancy outcomes were analyzed. In addition, the multivariate Logistic Regression model was used to investigate the related factors affecting pregnancy outcome FET. Results Infertility time, age, endometrial thickness, P level, E2/P ratio and good quality embryo had a relationship with clinical pregnancy outcomes(P<0. 05,P<0. 01). Multi-variate logistic regression analysis showed that age, endometrial thickness and E2/P ratio could affect clinical pregnancy out-comes(P<0. 05,P<0. 01). Conclusion Regulating endometrial thickness, E2/ P ratio factors can improve clinical preg-nancy rate for patients undergoing FET in artificial cycle. Screening patients of suitable age is also an important means to im-prove the pregnancy rate.
