Abstract 【Objective】To investigate the correlation between endometriosis fertility index (EFI) and pregnancy rate after laparoscopic surgery in patients with endometriosis (EMT) associated infertility.【Methods】A total of 125 EMT-associated infertility patients admitted to our department were selected in this study. There were 38 cases of ovarian endometriotic cysts, 47 cases of peritoneal ectopic lesions, 32 cases of ovarian endometriotic cysts with peritoneal ectopic lesions, and 8 cases of adenomyosis. Laparoscopic surgery was performed and EFI scores were recorded after surgery. Follow-up was conducted for three years to obtain the annual pregnancy rate. The correlation between EFI and pregnancy rate was analyzed. The possible influencing factors of postoperative pregnancy outcomes were conducted by logistic analysis as well. 【Results】 The pregnancy rate was 30.40% in the first year after surgery, 14.40% in the second year, and 4.00% in the third year. The cumulative pregnancy rate after three years was 48.80%. There were no significant differences in the three-year cumulative pregnancy rate among the four different clinical types of EMT (P>0.05). The higher the EFI score, the higher the pregnancy rate was. Logistic regression analysis showed that the risk factors of postoperative pregnancy rate were uterine benign lesion, fallopian tubal occlusion, history of pelvic surgery, and EFI score. 【Conclusion】Laparoscopic EFI is an important index to evaluate the fertility of patients with EMT associated infertility. The risk factors of pregnancy rate after laparoscopic surgery are uterine benign lesion, tubal occlusion, history of pelvic surgery, and EFI score.
