How Does An Erection Occur ?

How does a man achieve an erection? The complete mechanism of how an erection is made is still a mystery to scientists although we do know that the neural input from the brain is extremely important.

[Note: there are two types of erections : erection by arousal or erection by reflex. The latter refers to a kind of reflex action which is not sustainable and not suitable for sex. This can be seen in people with cord damage such as paraplegics.]

As far as we know, a real erection occurs when the nervous system activates a rapid increase in blood flow to the penile tissues. This is normally due to a sexual stimulation in the form of sight, sound, touch, taste or smell. Or just a sexual thought.

As you can see from the picture on your right, the increased bloodflow engorges the spongy tissues of the penis (Corpora Cavernosa).  At the same time, blood outflow is cut off and the penis becomes stiff and erect.

That's an erection for you!

Accordingly, to increase the size of an erection, there must be an increase in blood flow to the penile tissues. At the same time, the blood has to be prevented from leaving the penis.

But the tricky question is how to improve bloodflow to the penis? There are various products that can help in this including prescription drugs like Viagra and herbal aphrodisiac pills like VigRx Plus.

The difference is that Viagra is a drug that releases a certain chemical to "trick" the brain into believing a sexual stimulation is present. Thus the brain "sends" more blood to the penis tissues.While this is very effective, it has bad side effects including heart attack risks.

On the other hand, herbal aphrodisiac pills like VigRx Plus is natural and does not have any negative side effects. It works by facilitating better and more bloodflow to the penis when a man is sexually aroused. It does not target the brain and is therefore as instantaneous as Viagra.

However, herbal pills like VigRx Plus has other benefits helping you produce more semen and sperm for a better orgasm. Plus it is good for your prostate health, which is very important for maintaining male virility.
