Several abdomino-Pelvic surgical procedures can cause ejaculatory failure or impotence. Retroperitoneal lymph node dissection for testis cancer is followed by loss of ejaculation if bilateral. In low stage cancers, monolateral procedure is associated with maintenance of ejaculation in most patients. Evaluation of seminal fluid before surgery is essential for cryopreservation and artificial insemination erectile impotence is consequent to section of "nervi erigentes" in pelvic surgery for cancer. Careful anatomic dissection can spare these nerves but oncologic radicality should be always kept in mind.
