The ejaculatory problems caused by spinal cord injury can make it difficult for men to father children. However, there are some methods to stimulate ejaculation.
Penile vibratory stimulation involves applying a vibrator to the tip of the penis. (Men who lose sensation in their genitals should be careful not to injure the penis.)
With electroejaculation, a doctor inserts an electrical probe through the rectum and uses electrical stimulation to prompt ejaculation.
Sperm can also be retrieved from the testicles for use with in-vitro fertilization (IVF).
