Prostate cancer is the most prevalent non-cutaneous cancer in men worldwide. As a result of increased survival rates, men and their partners are living longer with the sexual sequelae of active treatments for prostate cancer, including surgery, radiotherapy and hormone therapy. The effect of erectile dysfunction on the patient and his partner is complex; many men experience psychosocial effects influenced by their hegemonic masculine beliefs. Some men experience difficulties in addressing their needs and require support while they attempt to reframe their beliefs about masculinity. The PLISSIT model can be used to guide healthcare practitioners in assessing and addressing the needs of this group of patients. The man’s partner should be included in assessment and interventions where appropriate.
