Main findings
The summarized estimation of results based on 49 RCTs showed that acupuncture might be a beneficial treatment for infertile women undergoing IVF. TEAS showed a significant benefit on both CPR and LBR improvement, while TA, WA, EA and LA were found significant effectiveness in CPR, but not significant for LBR. Subgroup analyses showed that the lower baseline estimate of the pregnancy rate had benefits on CPR and LBR.
