Sexual function and fecundity after treatment for testicular tumors

Questionnaires were mailed to patients who had undergone either radiotherapy, lymphadenectomy, or a combination of both as treatment for malignant disease of the testis in an attempt to define the effects of their therapy on sexual function, ejaculation, and fecundity. The forms returned by 29 patients with seminoma treated with irradiation alone indicated that little change had occurred in their sexual performance or sex drive. Diminished semen volume was reported by 10 patients but was severe in only 1. Two of 3 patients who desired children after therapy were successful. In patients with nonseminomatous testis tumor treated surgically, 42 of 50 reported a significant decrease in semen volume, but 7 of 12 who desired children following therapy were successful. The physiology of ejaculation is reviewed, and comments are offered on the means by which retroperitoneal lymphadenectomy may disrupt normal ejaculation.
