Acupuncture for prostatitis seems to be an effective intervention, according to the results of a Cochrane systematic review of non-pharmacological treatments for chronic prostatitis and chronic pelvic pain syndrome. Three of the studies included in the review, covering 204 patients, suggested that acupuncture reduces prostatitis symptoms in an appreciable number of patients, when compared against either standard interventions or a sham control procedure. Furthermore, the use of acupuncture resulted in little or no increase in adverse events, compared to standard medical therapy.
