A simple technique to prevent retrograde ejaculation during assisted ejaculation.

The aim of this study was to develop a technique which would prevent retrograde ejaculation in chronic spinal cord injured (SCI) patients undergoing vibration and electroejaculation procedures. A balloon catheter was used to tamponade the bladder neck in 12 patients who underwent 100 assisted ejaculation procedures. Antegrade ejaculations were collected on all occasions with no incidences of urine contamination and no sperm were seen in post ejaculatory urine. Silicone catheters had minimal effects on sperm motility and viability. All lubricant gels were found to adversely affect sperm quality and were not used.
