  • Efficacy and safety of local endometrial mechanical stimulation in patients with recurrent embryo implantation failure: a systematic review

    ObjectivesTo systematically review the efficacy and safety of local endometrial mechanical stimulation in patients with recurrent embryo implantation failure in vitro fertilization.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect clinical controlled studies on the efficacy and safety of local endometrial mechanical stimulation in patients with recurrent embryo implantation failure from inception to March 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 10 studies, including 8 randomized controlled trials and 2 case-control studies, and involving 1 274 patients were included. The results of meta-analysis showed that: the clinical pregnancy rate of endometrial mechanical stimulation group was higher than that of control group (RR=1.40, 95%CI 1.04 to 1.89, P=0.03). However, no significant differences were found in implantation rate (RR=0.75, 95%CI 0.50 to 1.13, P=0.17), live births rate (RR=1.38, 95%CI 0.99 to 1.93, P=0.06), miscarriage rate (RR=0.83, 95%CI 0.55 to 1.24, P=0.36) and rate of multiple pregnancy (RR=0.90, 95%CI 0.61 to 1.35, P=0.63).ConclusionCurrent evidence shows that, for patients with repeated implantation failure, mechanical endometrial stimulation before re-transplantation may help to improve the clinical pregnancy rate of test-tube infants, however, it has no significant effects on implantation rate, live birth rate, abortion rate, multiple pregnancy rate and ectopic pregnancy rate. Due to limited quality and quantity of the included studies, more high quality studies are needed required to verify above conclusions.
