ED that cannot be linked to physical causes has been successfully treated by hypnosis.⁴ In one trial, three hypnosis sessions per week, later decreased to one per month, over a six-month period led to improvement in 75% of men in the trial.

Acupuncture might be of some benefit for men with ED. Electroacupuncture, which is acupuncture accompanied by electrical stimulation, was performed on various acupuncture points in men with ED in a preliminary trial of men with this condition.⁵ Two treatments were administered every week for one month. An improvement in quality of erection was observed in 15% of the participants and an increase in sexual activity was reported by 31% of the men. Another preliminary trial⁶ found good results in over half of the men treated, but the only controlled trial of electroacupuncture for ED⁷ found that placebo also produced a large improvement in sexual function—an effect similar to that of acupuncture. Controlled trials with larger groups of men are necessary to better test the efficacy of acupuncture therapy for men suffering from ED.
