Erectile dysfunction (ED) is defined as the persistent inability to achieve and/or maintain a penile erection sufficient to permit satisfactory sexual performance (1)
- although a benign condition, ED may have a significant impact on the quality of life of the sufferers as well as their partners
- ED is also considered as an early warning sign of potential cardiovascular disease (1)
Erection requires an intact parasympathetic reflex at S2 and S3. Ejaculation requires an intact sympathetic L1 root.
