Erectile dysfunction (ED) has detrimental social and psychological effects on the quality of life of affected individuals and their sexual partners. When medical intervention is introduced to treat ED, physicians, nurses, and clinical educators should consider this disorder as a shared health problem for the men with ED and their sexual partners. New therapeutics such as phosphodiesterase-5 inhibitors improve erectile function in affected men, and the ultimate goal of medical intervention for ED should be achievement of a satisfactory sex life for couples engaged sexual relationships. Sexual partners of men with ED have an important role in its management and improvement in quality of sex life; therefore, they should be involved in assessment of, diagnosis, education, counselling, and choice of therapy. This sexual- partner-engaged approach might assist treatment and rehabilitation, helping the couples affected by ED to achieve a high-quality sex life.
