Background: Moderate to severe intrauterine adhesions (IUAs) may greatly impact fertility, predisposing to pregnancy and obstetric complications. The impact of mild IUAs on reproductive performance remains unclear. A systematic review and meta-analysis was performed to examine the long-term reproductive outcomes in women with hysteroscopic identified and treated mild IUAs mild intrauterine adhesions (IUAs) Methods: An electronic literature search was conducted using MEDLINE and EMBASE from inception to June 2019. All prospective cohort, cross-sectional studies or randomized controlled trials Clinical trials in which reproductive outcomes of women with mild IUAs, were reported were included. Results: Five studies, reporting on reproductive outcomes of 229 women with hysteroscopic identified and treated mild IUAs, were included. The pregnancy rate was 62.3% (142 of 228; 95% CI: 0.55–0.72, I 2 25%, p =.21) and in 86.6% (123 of 142) a live birth was encountered (95% CI: 0.71–0.97) with 83.1% (108 out of 130) term deliveries (95% CI: 0.53–0.95). A miscarriage was reported in 10% (13 of 130; 95% CI: 0.02–0.26). Due to the lack of a control group, reproductive outcomes were compared to a general population. Pregnancy and live birth rates were significantly lower in women with identified and treated mild IUAs, 90% versus 62.3% and respectively 99.5% versus 86.6%. The miscarriage rate was similar. Data on obstetric and neonatal outcomes are lacking. Conclusions: Women with hysteroscopic identified and treated mild IUAs seem to have lower pregnancy and live birth rate compared to the general population. Future studies consisting of a large cohort of women with hysteroscopic identified and treated IUAs with structural follow-up and a control group are needed to confirm our findings.
