Endometriosis fertility index (EFI) is a robust tool to predict pregnancy rate in endometriosis patients who are attempting non-in vitro fertilization conception. However, EFI calculation requires laparoscopy. Newly established imaging techniques such as sliding sign, that is used to diagnose Pouch of Douglas obliteration, could provide a promising alternative. The objective of this study is to investigate the practicality of using ultrasound data to predict low EFI (score ≤6).
