10. How does SCI affect sexual function and what can be done to improve such function?

Most people with spinal cord injury above the T10 will continue to have reflex erections associated with stimulation. Some people may have prolonged erections called priapism. A majority can have ejaculation although increased stimulation including vibration may be required. In many people, ejaculation may be retrograde, i.e. the ejaculate goes into the bladder rather comes out, because the external sphincter may be open. Retrograde ejaculation should not be harmful or cause urinary tract infections. A serious associated complication of sexual intercourse in both men and women is the occurrence of autonomic dysreflexia (AD) with orgasm, with associated headaches and other symptoms of AD. These can be treated with drugs to lower blood pressure (see answer to AD above). In addition, sexual intercourse may be associated with increased spasticity and spasms. People with injuries below T10 may have damage to the spinal cord centers responsible for erection and ejaculation. Many techniques are available to increase erection, including drugs such as Sildenafil (Viagra), vacuum pumps, cock rings, and penile prostheses. Several studies have reported that women with “complete” spinal cord injury can achieve orgasms, possibly through neural pathways outside of the spinal cord.
