A Cochrane Database systematic review by Italian authors looking at acupuncture for prostatitis/chronic pelvic pain syndrome, has concluded that based on short term follow up, acupuncture reduces prostatitis symptoms in an appreciable number of participants compared with sham procedure. In an appreciable number of patients, it probably also decreases prostatitis symptoms when compared with standard medical therapy. In all, the authors examined 38 studies covering 3300 men, which made 23 comparisons between different treatment and lifestyle interventions.
