ED can in many cases be treated by drugs taken orally, injected, or as penile suppositories. These drugs increase the efficacy of nitrous oxide, which dilates the blood vessels of corpora cavernosa. When oral drugs or suppositories fail, injections into the erectile tissue of the penile shaft are extremely effective but occasionally cause priapism.

Its causes remain a mystery, Vorona said, but some evidence suggests it's related to reduced levels of iron and the neurotransmitter known as dopamine in the brain. Those who have the neurological disorder complain of an almost irresistible urge to move their legs. Psychological factors are responsible for about 10%-20% of all cases of ED. It is often a secondary reaction to an underlying physical cause. In some cases, the psychological effects of ED may stem from childhood abuse or sexual trauma.

Other drugs such as alcohol, cocaine, and heroin negatively impact male sexual libido.)
