Impulse magnetic-field therapy for erectile dysfunction: a double-blind, placebo-controlled study.

This double-blind, placebo-controlled study assessed the efficacy of 3 weeks of impulse magnetic-field therapy for erectile dysfunction (ED). Twenty volunteers who suffered from ED or orgasmic disturbances were randomly assigned to either active treatment or placebo (n = 10 each). Efficacy was assessed in terms of intensity and duration of erection, general well-being, sexual activity, and warm sensation in the genital area. In the active-treatment group, all efficacy endpoints were significantly improved at study end (P < or = .01), with 80% reporting increases in intensity and duration of erection, frequency of genital warmth, and general well-being. The remaining 20%, who experienced minor improvements, were found to have an influenza-like infection after the study that may have influenced their results. Only 30% of the placebo group noted some improvement in their sexual activity; 70% had no change. No side effects were reported.
