The first prospective, randomised, single-blind, placebo-controlled study of the effect of acupuncture in infertile men with severe oligoasthenozoospermia has shown that acupuncture can improve sperm motility. The German study, involving 29 men compared TCM acupuncture with placebo acupuncture. A significantly higher percentage of motile sperm was found after real acupuncture. No effect of acupuncture on sperm concentration was observed. (A prospective randomized placebo-controlled study of the effect of acupuncture in infertile patients with severe oligoasthenozoospermia.
