Spinal injury sperm mystery: 18-Month study seeks answers

NCT ID NCT02144558

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study followed 35 men with spinal cord injuries over 18 months to see how their sperm quality changes and what factors might cause problems. Researchers measured sperm health, inflammation, and infections from ejaculates collected every 6 months. The goal is to find ways to preserve fertility and reduce the need for advanced fertility treatments.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to
If successful, this study could identify key risk factors that harm sperm quality in spinal cord injured men, leading to better long-term fertility care and possibly reducing the need for assisted reproduction.
What could go wrong
This is a small observational study with only 35 participants, so findings may not apply to all spinal cord injured men. It does not test any treatment, so it cannot directly improve fertility.
