The degree of sexual function after spinal cord injury often depends on the location and severity of the injury. Some common sexual problems for men are:
Erectile dysfunction (ED). Men with ED are unable to achieve or sustain an erection necessary for satisfying sex. A number of treatments are available, although some work better than others. For example, men who lose hand function might have trouble managing penile injections for ED.
Ejaculatory problems. Some men with spinal cord injury are unable to ejaculate (anejaculation). Others have retrograde ejaculation; their semen flows backward into the bladder instead of out the tip of the penis.
