The effects of treatment for cancer on male fertility and sexuality.

The sequelae of some treatments for cancer, by virtue of their systemic action, adversely affect three aspects of male sexuality: desire, physical function, and cytokinetic gonadal processes. Other more localized therapies, such as surgery and radiation therapy, may affect only one aspect. Frequently, the effects of cancer therapy are interrelated, thus making it difficult to identify any single problem. This article discusses the impact of medical therapy, including chemotherapy, surgery, radiation therapy, and hormonal manipulation, as they relate to male sexuality. Interventions to promote sexual rehabilitation, either by intensive therapy or nursing actions, are discussed.
