Although the revised American Fertility Society score (rAFS score) has been widely used to indicate the severity of endometriosis, it is difficult to predict the possibility of postoperative pregnancy using it. Recently, the Endometriosis Fertility Index (EFI) was proposed as a scoring system useful for predicting the possibility of non-IVF pregnancy after the surgery. Nevertheless, it remains unclear whether EFI is similarly useful in Japanese women. Therefore, in this study, we evaluated the usefulness of EFI in Japanese patients. Method) We enrolled 57 infertile endometriotic patients who underwent laparoscopic surgery followed by non-IVF treatment at Kyoto University Hospital between January 1999 and May 2012. Firstly, the EFI and rAFS score were compared between the pregnancy (n=35) and non-pregnancy (n=22) groups. Next, cumulative pregnancy rates in the EFI≦6 group and EFI≧7 group were compared using the Kaplan-Meier method. Finally, multivariate analysis was conducted to assess the correlation between pregnancy and each component of the EFI. Results) The EFIs in the non-pregnancy group was significantly lower than that in the pregnancy group (mean±SD: 5.68±1.42 vs. 6.86±1.42, respectively). On the other hand, the difference did not reach significance for rAFS scores. The cumulative pregnancy rate in the EFI≦6 group was significantly lower than that in the EFI≧7 group. On multivariate analysis of the EFI, the strongest (but not significant) correlation was observed for the age of patents. Subgroup analysis of patients aged 35 years or younger showed that the EFI of the non-pregnancy group was significantly lower than that of the pregnancy group. In contrast, no difference was observed in the patients aged 36 years or older. Conclusion) The EFI but not rAFS score was correlated with the possibility of postoperative non-IVF pregnancy in endometriotic Japanese women. EFI≦6 could be considered as a low pregnancy potential. The EFI might be useful to select patients who require an early treatment step-up to IVF after surgery for endometriosis.
