Evaluation of magnetic stimulation as a non-invasive technique in treating different causes of erectile dysfunction: a prospective cohort study.

Background: Elaboration of alternative therapeutic modality is needed, which should be safer, less costly and with no side effects. Functional Magnetic Stimulator (FMS) is a technique that was approved by the US Food and Drug Administration in 1998. We aimed to evaluate the efficacy of FMS in treating different causes of erectile dysfunction (ED).

Results: The mean baseline 15 items of the international index of erectile function (IIEF-15) scores of groups A (arteriogenic ED), B (veno-occlusive ED) and C (psychogenic ED) were 12.8 ± 2.6, 16.2 ± 3.3 and 27.5 ± 3.7, respectively. The mean post sessions IIEF-15 scores of groups A, B and C were 23.4 ± 4.1, 31.5 ± 3.5, 49.2 ± 3.5, respectively. The mean baseline domains of erectile function (EF) scores of groups A, B and C were 3.8 ± 2, 5.8 ± 3.5 and 11.5 ± 3.1, respectively. The mean post sessions domains of EF scores of groups A, B and C were 10.6 ± 3.1, 15 ± 3.6 and 24.8 ± 2.9, respectively. The mean baseline domains of orgasmic function scores of groups A, B and C were 3.3 ± 0.9, 3.9 ± 0.5 and 4.8 ± 0.4, respectively. The mean post sessions domains of orgasmic function scores of groups A, B and C were 4.8 ± 0.8 5.9 ± 1.0 and 8.6 ± 0.5, respectively. The mean baseline domains of sexual desire scores of groups A, B and C were 2.6 ± 0.6, 3.1 ± 0.7 and 4.8 ± 0.7, respectively. The mean post sessions domains of sexual desire scores of groups A, B and C were 3.6 ± 0.5, 4.4 ± 0.7 and 6.6 ± 0.6, respectively. The mean baseline domains of intercourse satisfaction scores of groups A, B and C were 1.9 ± 0.5, 2.4 ± 0.6 and 4.1 ± 0.6, respectively. The mean post sessions domains of intercourse satisfaction scores of groups A, B and C were 2.6 ± 0.5, 3.6 ± 0.5 and 5.5 ± 0.6, respectively. The baseline domains of overall satisfaction scores of groups A, B and C were 1.1 ± 0.3, 1.1 ± 0.3 and 2.4 ± 0.7, respectively. The mean post sessions domains of overall satisfaction scores of groups A, B and C were 2 ± 0.7, 2.7 ± 0.7 and 3.8 ± 0.7, respectively.

Conclusions: All patients showed significant improvement regarding domains of the IIEF-15 especially psychogenic cases following the sessions of FMS. Future studies should demonstrate the impact of these sessions on the response of poor responders to phosphodiesterase inhibitors and intracorporeal injections.
