Acupuncture therapy on patients with recurrent implantation failure can improve the pregnancy outcome of patients. It is a relatively effective treatment with satisfactory safety and suitable for clinical application.
The aim of this analysis was to identify the efficacy and safety of acupoint stimulation therapy for RIF patients. The results of meta-analysis show that for the outcome measurements including clinical pregnancy rate, biochemical pregnancy rate, embryo implantation rate, and endometrial thickness, the use of acupuncture in the treatment group is higher than the sham or nonacupuncture group, in which the difference is statistically significant. These results are believable and reliable. The included studies are highly homogeneous and there is no obvious publication bias. However, large heterogeneity appears in the statistical analysis of the endometrial thickness. Moreover, there was no statistical significance in the number of embryo transfers and the type of endometrium.
