If you want a rock hard erection then you need plenty of nitric oxide produced in the body, in fact, if you don't have enough of it not only will you fail to get a rock hard erection, you will fail to get an erection at all.

The erection process begins with sensory and mental stimulation and these are transmitted to the blood vessels of the penis and the release of nitric oxide is triggered. Nitric oxide secretion, causes the muscles of the penis to relax and expand allowing blood to flow into the spongy tissue of the penis, then fill it with blood and an erection is the result.

The Key Role of Nitric Oxide

If you don't get enough nitric oxide then you will never get an erection. Nitric Oxide production decreases with age and many men who think they can only get an erection taking drugs simply need to increase their production of nitric oxide.

In fact, lack of nitric oxide is a far more common problem in terms of erectile dysfunction than lack of testosterone.

There are many natural supplements that are proven to increase the production of Nitric Oxide.
