We report on our experience with autoinjection therapy in 72 patients with erectile dysfunction. We analysed factors that have an impact on the outcome of autoinjection therapy, and we focused on psychological, sexological and relational issues. In 53 (74%) patients an organic aetiological factor was found. Although with the aid of injection 82% of the men were able to achieve an erection adequate for penetration, only 39% continued treatment beyond one year. Lowest drop-out rates were encountered among patients with diabetes mellitus and men without organic aetiology (50% and 53% respectively). The most important reason for discontinuation was lack of acceptance of autoinjection therapy by the partner. Other reasons were prolonged erection, haematomas, ineffectiveness and fear of self-injection. Although autoinjection provides a safe and effective long-term method for the treatment of erectile dysfunction, the drop-out rate is strikingly high. Apparently, the acceptance of the partner is the most important determinant of the result of autoinjection therapy. Therefore, the partner should be involved in the counselling and treatment from the beginning.
