Patients treated for testicular cancer have increased risk of ejaculatory, orgasmic and erectile dysfunction compared with healthy men. The underlying relations are unclear. This review describes sexual dysfunctions that are associated with various treatment modalities. One meta-analysis and 11 original works were examined. About one third of the patients experience one or more sexual problems in relation to the treatment. Only retroperitoneal surgery can cause a specific sexual dysfunction, namely loss of ejaculation ability or ejaculatory functioning. Psychosexual causes are important for understanding sexual dysfunctions in patients with testicular cancer.
