Abstract Objective: To investigate the value of endometriosis fertility index (EFI) for predicting natural pregnancy of women after endometriosis (EMT) surgery. Methods: From May 2010 to October 2013, 200 infertility women with endometriosis who underwent laparoscopic and hysteroscopy surgery were enrolled in this study. EFI score of included women was performed after surgery, and these women were followed up based on their acceptable mode. The pregnancy situation and the cumulative natural pregnancy rate of the women with different EFI scores after operation were recorded. The receiver operating characteristic (ROC) curve was used to evaluate the value of EFI scores for predicting the natural pregnancy of women after operation. Results: The data of total 108 women were included for analysis. The natural pregnancy rate of women in 5 years followed-up was 75.9% (82 cases), and the cumulative natural pregnancy rate of women with EFI 0-3 scores was 25.0%, that of women with EFI 4 scores was 46.2%, that of women with EFI 5 scores was 62.5%, that of women with EFI 6 scores was 77.8%, that of women with EFI 7-8 scores was 86.7%, and that of women with EFI 9-10 scores was 92.6%. ROC curve analysis showed that the critical value of EFI for predicting natural pregnancy within 12 months after surgery was 7.37, the area under the ROC curve was 0.769 (95% CI 0.565-0.972, P<0.05), its sensitivity was 54.5%, and its specificity was 90.9%. Conclusion: EFI can be used to predicting the natural pregnancy of women after EMT surgery, which can provide evidence for clinical treatment selection.
