The Endometriosis Fertility Index Is Useful for Predicting the Ability to Conceive without Assisted Reproductive Technology Treatment after Laparoscopic Surgery, Regardless of Endometriosis.

Abstract:

OBJECTIVE:The endometriosis fertility index (EFI) is a novel index for predicting pregnancy after surgery. We investigated the utility of the EFI for predicting the ability to conceive without assisted reproductive technology (ART) treatment after laparoscopic surgery. METHODS:From July 2011 through December 2012, we recruited 133 infertile patients who underwent laparoscopy, and the EFI was calculated. After surgery, 55 of 133 achieved pregnancy without ART treatment. We evaluated the factors that predicted a naturally successful pregnancy and compared them between the pregnant and non-pregnant subjects. RESULTS:On a univariate linear regression analysis, we found that a younger age, shorter duration of infertility, and higher EFI were positively associated with a successful pregnancy without ART after laparoscopic surgery (p < 0.05). According to 50th percentile EFI, the cutoff EFI predicting a successful pregnancy without ART was 7, the pregnancy rate in the high-EFI group (EFI; 8-10) was significantly higher than that in the low-EFI group (EFI ≤7; p < 0.05), but the duration to natural conception after surgery was similar between the 2 groups. CONCLUSION:The EFI possesses greater predictive power for a successful pregnancy with natural intercourse or intrauterine insemination in infertile patients, regardless of endometriosis, than the Revised-American Society of Reproductive Medicine classification.
