Abstract

Abstract : INTRODUCTION: Infertility may occur in women with Crohn's disease (CD) and ulcerative colitis (UC), especially after surgery such as ileal pouch-anal anastomosis (IPAA). Assisted reproductive technology (ART) may be an option, but the safety and efficacy in this setting has been based on small cohorts to date. We performed a systematic review and meta-analysis to address this data gap. METHODS: A systematic review and random-effects meta-analysis was performed until May 2020. The primary outcomes were pregnancy and live birth rates per cycle of ART. RESULTS: Eleven studies met inclusion criteria for the systematic review and 4 for the meta-analysis. Compared with the general population, women with CD (with and without previous surgery) had no difference in pregnancy rates (odds ratio [OR] = 0.69, 95% confidence interval [CI]: 0.45–1.05) but had reduced live births (OR = 0.67, 95% CI: 0.53–0.85) per cycle of ART. ART live birth rates are not reduced in women with medically managed CD; however, they are 49%–71% lower after CD-related surgery. Women with UC had no difference in both pregnancy rates (OR = 0.99, 95% CI: 0.63–1.55) and live birth rates (OR = 0.88, 95% CI: 0.67–1.17); however, live birth rates were reduced after IPAA failure (hazard ratio = 0.36, 95% CI: 0.14–0.92). Two studies did not identify any significant safety signals. DISCUSSION: ART is safe and effective in patients with UC and medically managed CD, with pregnancy and live birth rates similar to that of the general population. However, within the limitations of the available literature, current data suggest that efficacy is reduced in women with CD-related surgery and IPAA failure. Greater gastroenterologist awareness of ART is needed to facilitate timely fertility therapy referral when indicated, particularly in CD. Abstract :
