This study developed a bladder neck tamponade technique using a balloon catheter to prevent retrograde ejaculation in spinal cord injured (SCI) patients undergoing assisted ejaculation, ensuring antegrade ejaculation without urine contamination.

Area of Science:

  • Reproductive medicine
  • Urology
  • Neuroscience

Background:

  • Spinal cord injury (SCI) often causes ejaculatory dysfunction, including retrograde ejaculation.
  • Assisted reproductive technologies like vibration and electroejaculation are used for sperm retrieval in SCI patients.
  • Retrograde ejaculation, where semen enters the bladder, hinders fertility and requires management.

Purpose of the Study:

  • To develop and evaluate a technique to prevent retrograde ejaculation in chronic spinal cord injured patients during assisted ejaculation procedures.
  • To ensure antegrade ejaculation and prevent urine contamination of samples.
  • To assess the impact of the technique and materials on sperm quality.

Main Methods:

  • A balloon catheter was utilized to tamponade the bladder neck in 12 spinal cord injured patients.

Related Experiment Videos

  • A total of 100 assisted ejaculation procedures (vibration and electroejaculation) were performed using the catheter technique.
  • Sperm samples were collected for antegrade ejaculation, and post-ejaculatory urine was analyzed for contamination.
  • Sperm motility and viability were assessed, considering the effects of silicone catheters and lubricant gels.

    • Main Results:

    • The bladder neck tamponade technique successfully prevented retrograde ejaculation in all 100 procedures.
    • Antegrade ejaculation was achieved consistently, with no instances of urine contamination.
    • No sperm were detected in post-ejaculatory urine samples.
    • Silicone catheters demonstrated minimal adverse effects on sperm motility and viability.
    • Lubricant gels were found to negatively impact sperm quality and were therefore excluded.

    Conclusions:

    • Bladder neck tamponade with a balloon catheter is an effective method to prevent retrograde ejaculation in spinal cord injured patients undergoing assisted ejaculation.
    • This technique facilitates successful antegrade ejaculation and maintains sample integrity for fertility treatments.
    • The chosen materials, specifically silicone catheters, are compatible with sperm quality, while lubricants should be avoided.
