Summary

Electroejaculation effectively treats anejaculation in patients with spinal cord injury or post-surgical complications. While complications like autonomic dysreflexia can occur, they are temporary and the procedure is considered safer than alternative treatments.

Area of Science:

  • Reproductive Medicine
  • Urology
  • Neuroscience

Context:

  • Anejaculation, the absence of ejaculation, significantly impacts male fertility.
  • Spinal cord injury (SCI) and radical rectal cancer surgery are common causes of anejaculation.
  • Existing artificial ejaculation methods have limitations, necessitating safer and more effective alternatives.

Purpose:

  • To evaluate the clinical utility of electroejaculation for treating anejaculation in SCI and post-surgical patients.
  • To compare the efficacy of Brindley's and modified Seager's electroejaculation techniques.
  • To assess the safety and complications associated with electroejaculation.

Summary:

  • Forty-one patients with anejaculation (40 SCI, 1 post-rectal cancer surgery) underwent electroejaculation using Brindley's and/or modified Seager's techniques.

  • Modified Seager's technique, utilizing bipolar pulses, achieved higher success rates (24/29 patients) compared to Brindley's (11/18 patients).
  • Common complications included autonomic dysreflexia and pain, which were transient and resolved post-procedure, suggesting a favorable safety profile over neostigmine injections.
  • Semen quality analysis indicated a decline in sperm count with extended intervals post-SCI and low motility even in the early stages, suggesting rapid testicular dysfunction.

    • Impact:

    • Electroejaculation, particularly the modified Seager's technique, offers a viable and relatively safe treatment option for anejaculation in specific patient populations.
    • The findings highlight the importance of early intervention for fertility preservation in SCI patients due to rapid testicular dysfunction.
    • This study contributes to optimizing assisted reproductive technologies for men with neurological or surgical-induced anejaculation.
