Objective: To determine if Endometriosis Fertility Index (EFI) is useful to estimate the reproductive outcome in infertile patients with diagnosis and surgical treatment of endometriosis. Design: Retrospective cohort study. Material and Methods: The medical records of 65 patients who consulted for infertility from April 2011 to September 2014 which underwent a diagnostic videolaparoscopy with the same surgical operators and findings of endometriosis were analyzed. All those patients with severe male factor, cervical factor and those who underwent high complexity treatments were excluded from the analysis. Data from surgical factors for categorization of patients according to EFI was obtained from videos of laparoscopy, and historical factors were collected from medical records. The pregnancy rate was evaluated after an 18-month follow-up. Patients were divided according to EFI values obtained in 3 groups, and cumulative pregnancy rates among these groups were compared. Results: The mean age of the patients was 33.5 years (SD = 2.7). The mean infertility time was 2.8 years (SD = 1.5), and primary infertility accounted for 80[%] of the patients. The total pregnancy rate was 47.7[%], being 12.5[%] in group 1, 35.7[%] in group 2 and 69[%] in group 3. Conclusions: It was observed that in patients with higher EFI category, the probability of spontaneous pregnancy or low complexity treatment was increased within 12 months after laparoscopy, in a statistically significant way (p = 0.002). This allows us to validate the EFI as a useful tool to estimate the reproductive prognosis of infertile patients diagnosed with endometriosis.
