Summary
Penile vibration successfully induced ejaculation in most men with spinal cord injuries, though semen quality was generally poor. This method offers a potential avenue for fertility preservation in this population.
Area of Science:
- Neuroscience
- Reproductive Medicine
- Urology
Context:
- Men with spinal cord injuries often experience ejaculatory dysfunction.
- Existing fertility treatments for this population can be invasive or limited in efficacy.
Purpose:
- To evaluate the efficacy of penile vibration in achieving reflex ejaculation in men with spinal cord injuries.
- To assess the quality of semen obtained through penile vibration.
Summary:
- Thirty-six men with spinal cord lesions underwent penile vibration therapy.
- Sperm cells were obtained in 27 participants, with 16 achieving antegrade ejaculation and 11 retrograde ejaculation.
- Semen quality was generally poor, characterized by reduced sperm count and motility, and increased abnormal morphology.
Impact:
- Penile vibration is a viable, non-invasive method for inducing ejaculation in men with spinal cord injuries.
- The study highlights the potential for fertility preservation, despite compromised semen parameters.
- Autonomic hyperreflexia was a rare side effect, manageable with medication.
