Effect of assisted hatching on pregnancy outcomes: a systematic review and meta-analysis of randomized controlled trials.

ABSTRACT: Emerging evidence suggests that assisted hatching (AH) techniques may improve clinical pregnancy rates, particularly in poor prognosis patients; however, there still remains considerable uncertainty. We conducted a meta-analysis to verify the effect of AH on pregnancy outcomes. We searched for related studies published in PubMed, Web of Science, and Cochrane library databases from start dates to October 10, 2015. Totally, 36 randomized controlled trials with 6459 participants were included. Summary odds ratios (ORs) with 95% confidence intervals (CIs) for whether by AH or not were estimated. We found a significant increase in clinical pregnancy (OR = 1.16, 95% CI = 1.00-1.36, I(2) = 48.3%) and multiple pregnancy rates (OR = 1.50, 95% CI = 1.11-2.01, I(2) = 44.0%) with AH when compared to t
