Seventy-three percent of patients was found to have mild-severe erectile dysfunction according to the IIEF. Type of erection was associated with the level of the injury.Conclusion: Spinal cord injury usually affects young men; life expectancy for this group is getting longer, nearly reaching that of the normal population.
