Background: Previous studies have given an inaccurate assessment of the role of acupuncture in in vitro fertilization (IVF). We will use acupuncture doses as an entry point, discussing the dose-related effects of acupuncture therapy in women undergoing IVF.
Methods: This study will search the following database: EMBASE, PubMed, Web of Science, the Cochrane Central Register of Controlled Trials (CENTRAL), and 4 Chinese databases. All databases will be searched from the date of database establishment to January 31, 2019. In addition, we will search possible studies which were included in previous meta-analyses. The primary outcomes are the clinical pregnancy rate (CPR) and the live birth rate (LBR). The secondary outcomes involved the biochemical pregnancy rate (BPR), the ongoing pregnancy rate (OPR), serum hormone level, the incidence of ovarian hyper-stimulation syndrome (OHSS), the cycle cancellation rates, and adverse events (AEs). After checking and integrating the raw data, we will use a 2-step to conduct the meta-analysis. Firstly, we will assess the effect of acupuncture on in vitro fertilization and embryo transfer (IVF-ET). Secondly, the meta-analysis will be performed for studies with similar total number of treatment sessions to investigate the dose-related effects of acupuncture. RevMan V.5.3 statistical software will be used for meta-analysis. If it is not appropriate for a meta-analysis, then a descriptive analysis will be conducted.
Results: This study will investigate the relationship between pregnancy outcomes and the doses of acupuncture therapy in women undergoing IVF, and answer whether a higher-doses of acupuncture treatment will contribute to a better outcome of IVF-ET.
Conclusion: The funding of this meta-analysis may provide convincing evidence for clinicians, benefitting more patients who crave children.
