[Electroejaculation--effectiveness in a patient after retroperitoneal lymph node dissection--case report].

Semen was obtained by transrectal electrostimulation from male patient after retroperitoneal lymph node dissection who had not ejaculated since time of operation. Vibratory stimulation was unsuccessful. electroejaculation was done under general anaesthesia. A silicone catheter was used to tamponade the bladder neck and antegrade ejaculations were collected. The semen underwent seminological assessment and then was diluted 1:1 in egg yolk substrate containing 15% glycerol, equilibrated, divided into straws and frozen in nitrogen. The straws were then placed for storage in liquid nitrogen until the insemination.
