Retrospective review on effectiveness of high-amplitude penile vibratory stimulation for conservative sperm retrieval in anejaculatory men with spinal cord injury: an Asian case series

High-amplitude penile vibratory stimulation (PVS) is a first-line method for sperm retrieval in men with spinal cord injury (SCI). This study assesses its effectiveness in Asian men with SCI, where such evidence is lacking. The study reviewed records of SCI patients who underwent sperm retrieval trials and were subjected to high amplitude PVS using Viberect X3 after failing other stimulation methods. The study found that high-amplitude, high-frequency vibratory stimulation resulted in a 46.15% ejaculatory success rate. The success rate was higher (66.7%) in patients with lesions at T6 and above.

• 1
  The overall ejaculatory success rate using high amplitude PVS was 46.15%.
• 2
  Ejaculatory success rate was higher (66.7%) among patients with lesions at T6 and above compared to those with lesions below T6 (33.3%).
• 3
  All patients with successful ejaculation had intact conus medullaris reflexes, significant abdominal and lower limb spasticity, and positive spinal withdrawal reflexes.
