The treatment for psychogenic erectile dysfunction has been previously managed by non-medical methods consisting of counseling with a psychiatrist, psychologist or sex therapist. The success rate for treatment with counseling has not been uniformly successful. This paper compares the treatment of psychogenic erectile dysfunction using standard sex therapy and self-injection therapy using low-dose PGE1. Fifty men with psychogenic impotence were divided into two groups: standard sex therapy for twelve weeks or treatment using low-dose (2.5 - 5.0 microg) of PGE1. The results showed that men treated with low-dose PGE1 had a 47% improvement of obtaining an unaided erection compared to 58% improvement rate with sex therapy. 69% of patients in the PGE1 group were satisfied with their treatment compared to 75% receiving sex therapy. The frequency of intercourse reported in patient diaries for the two groups was similar (20.5 per month for PGE1 vs 20.0 per month for sex therapy. The reported duration of erection by patients receiving PGE1 therapy was longer than that reported by those receiving sex therapy (35 min vs 10 min). The comparison of the cost of treatment of the two treatment groups reveals that the sex therapy is approximately 25% more expensive than the PGE1 treatment. This pilot study demonstrates that the efficacy of PGE1 was numerically, though not statistically, less than sex therapy in the treatment of psychogenic impotence. The cost per positive outcome with PGE1 treatment is lower than that of sex therapy treatment making PGE1 more cost-effective.
