This prospective two-center study externally validated the Endometriosis Fertility Index (EFI) in 59 reproductive-aged women diagnosed with endometriosis and infertility who underwent laparoscopic surgery in two Indonesian hospitals between 2012 and 2016, with follow-up for two years. Using statistical analyses, the study found that younger age, infertility duration of at least 3 years, higher LF score, and an AFS score below 71 were significantly associated with pregnancy, and pregnant participants had a higher median EFI score than non-pregnant participants (7 [5–9] vs 4 [1–8], p<0.001). The paper does not highlight specific limitations beyond the external validation scope and its sample context. This paper is centrally about endometriosis — it externally validates the Endometriosis Fertility Index in an Indonesian cohort and evaluates associations between EFI components and subsequent pregnancy.

Abstract

Objective: To externally validate EFI in an Indonesian population. Methods: A prospective study was performed in 59 reproductive aged women diagnosed with both endometriosis and infertility who underwent laparoscopic surgery in Dr. Cipto Mangunkusumo and Carolus Hospital during the period of December 2012 to June 2016. Subjects were followed up for two years. Results: Statistical analyses suggested that younger age, infertility duration  3 years, higher LF score, and AFS score below 71 were significantly associated with pregnancy (p<0.001, p<0.001, p=0.035, p<0.001, respectively). Pregnant subjects had significantly higher median EFI score compared to the not pregnant group [EFI score 7 (5-9) vs 4 (1-8), p<0.001)]. Conclusion: Higher EFI score was significantly associated with higher pregnancy rate.

Objective

To externally validate EFI in an Indonesian population.

Methods

A prospective study was performed in 59 reproductive aged women diagnosed with both endometriosis and infertility who underwent laparoscopic surgery in Dr. Cipto Mangunkusumo and Carolus Hospital during the period of December 2012 to June 2016. Subjects were followed up for two years.

Results

Statistical analyses suggested that younger age, infertility duration ï‚£ 3 years, higher LF score, and AFS score below 71 were significantly associated with pregnancy (p<0.001, p<0.001, p=0.035, p<0.001, respectively). Pregnant subjects had significantly higher median EFI score compared to the not pregnant group [EFI score 7 (5-9) vs 4 (1-8), p<0.001)].

Conclusion

Higher EFI score was significantly associated with higher pregnancy rate. [Indones J Obstet Gynecol 2017; 5-3: 160-163]
