This review looks at a selected number of RCTs that examined the effect of acupuncture on sperm motility and count, but not morphology. From the 4 trials they examined, they report that motility and sperm concentration were significantly increased in the acupuncture groups (If trial designs are heterogeneous, as they were in this meta analysis, it makes it more difficult to draw firm conclusions at this stage).
