Improvement of Reproductive Function in Men With Spinal Cord Injury (SCI)

Improvement of Reproductive Function in Men With Spinal Cord Injury (SCI)

This is a study of infertility which often occurs in men with spinal cord injury. Most men with spinal cord injury have a normal sperm count but abnormally low sperm motility - which means that the sperm does not swim well. This study will determine if a medicine given by mouth will improve sperm motility in men with spinal cord injuries. The medicine is called probenecid.
