How does nitric oxide help with erections?

Harris H. McIlwain, MD
Rheumatology
The nerves to the penis are important in the release of nitric oxide, which is important in producing erections. Nitric oxide has been found by researchers to be low in cases of people with nerve damage. With no nitric oxide, the small blood vessels which usually relax do not open to allow blood flow to increase in the penis. This is more often a long-lasting or permanent change which can limit erection. Nerve damage of this type is more common in smokers and in those over age 40.
