The cut-off EFI score obtained from the receiver operating characteristic (ROC) curve was 8 (AUC, 0.79; sensitivity, 0.67; specificity, 0.82). Rate of spontaneous pregnancy with EFI scores ≤ 7 was significantly lower than that with EFI scores ≥ 8 (18% vs. 67%, P = 0.028). Infertility treatment with assisted reproductive technology (ART) increased pregnancy rates in the lower EFI score group.\nConclusion: We confirmed that the EFI was a reliable prediction tool for spontaneous pregnancy in patients with surgically treated endometriosis. In infertile patients with EFI scores ≤ 7, ART therapy should be recommended.\n© 2021 日本産科婦人科内視鏡学会","source_license":"CC0","license_restricted":false}
