Cancer-related diagnosis and treatments can profoundly affect every aspect of an individual's life. The negative impact on the sexual sphere can manifest with onset or worsening of the most frequent male form of sexual dysfunction, that is the erectile dysfunction (ED), with an estimated incidence ranging from 40 to 100% in patients living with cancer. Cancer and ED are strictly related for many reasons. First, the psychological distress, the so-called 'Damocles syndrome', afflicting cancer patients contributes to ED onset. Second, all cancer therapies can variably lead to sexual dysfunction, even more than the disease itself, having both direct or indirect effects on sexual life. Indeed, alongside pelvic surgery and treatments directly impairing the hypothalamus-pituitary-gonadal axis, the altered personal-body-image frequently experienced by people living with cancer may represent a source of distress contributing to sexual dysfunction. It is undeniable that sexual issues are currently neglected or at least under-considered in the oncological setting, mainly due to the subjective lack of preparation experienced by healthcare professionals and to scant information provided to oncological patients on this topic. To overcome these management problems, a new multidisciplinary medical branch called 'oncosexology' was set up. The aim of this review is to comprehensively evaluate ED as an oncology-related morbidity, giving new light to sexual dysfunction management in the oncological setting.
