The current literature suggests that acupuncture reduces endometriosis-related pain and serum CA-125 levels, regardless of the control intervention used.
Of the 10 studies included, only one pilot study used a placebo control and assessed blinding; the rest used various controls (medications and herbs), which were impossible to blind. The sample sizes were small in all studies, ranging from 8 to 36 patients per arm. The mean difference (MD) in pain reduction (pre- minus post-interventional pain level—measured on a 0–10-point scale) between the acupuncture and control groups was 1.36. Acupuncture had a positive effect on peripheral blood CA-125 levels, as compared with the control groups. Similarly, the effect of acupuncture on clinical effective rate was positive, as compared with the control groups.
