Though a large number of men are not aware of this, nitric oxide plays a very important role in helping them get hard and firm erections.
When you get sexually excited, your brain signals your body to increase the blood flow to the penis. It is in the walls of the blood vessels that supply blood to the penis that this chemical is released. It helps penis muscles to relax so that blood vessels can dilate or open up. When the blood vessels dilate they allow more blood to flow into the penile chambers and make it swell. This blood is trapped in the erectile tissue and an erections is achieved.
The production of this highly crucial chemical declines with age and this decline not only affects male libido but also impairs your ability to attain and sustain a hard and firm erection. In other words, it results in erectile dysfunction or impotence.
Another crucial aspect that gets impaired with age and affects your sexual function is the blood circulation to the penis. Poor blood flow to the penis is also an underlying factor in erectile dysfunction. Not only this, your testosterone levels also plummet with age. Since it is the hormone that regulates sex drive and sexual function in men, a decline in testosterone inevitably results in reduced sex drive which triggers erectile dysfunction.
Nonetheless, there are some natural ways to get over the above problems. L-arginine helps in the secretion of nitric oxide. It is an amino acid that not only helps enhance sex drive but also helps you gain muscle. This is the reason why most bodybuilders take L-arginine supplements.
Food sources of L-arginine include animal protein, dairy, poultry, nuts and beans etc.,
Apart form L-arginine, there are some herbs that have been used for thousands of years to enhance blood circulation and overcome sexual dysfunction. Some of such herbs include ginseng, ginkgo, tribulus terrestris etc.,
There are some supplements that are packed with the above herbs and amino acids and have gained immense popularity not just because they are highly effective but also because they are completely safe and devoid of any side effects.
