Erections in men may be affected after a spinal cord injury, and ejaculation may be more difficult. Your doctor or urologist can discuss medical options for support. Sensation in the affected area may also be compromised, necessitating alternative stimulation. While orgasms are possible, they may be experienced differently, and spasms may occur. The amount of semen may be reduced or flow back into the bladder, leading to a lack of ejaculation. However, reproductive medicine can assist men with spinal cord injuries in fathering children, although this typically requires medical assistance.
The information above is from a publication by the University Hospital Balgrist titled "Spinal Cord Injury in Daily Life." For more in-depth discussions, individuals can consult doctors specializing in neuro-urology.
We highly recommend the book "Sexuality in Spinal Cord Injury – Answers to Your Questions". [2]
