Order Viagra Pills
Erectile dysfunction is when a man is unable to get an erection when sexually aroused or maintain an erection while engaged in intercourse or sexual activity. The condition is caused by an insufficient flow of blood to the tissue of the penis, called the corpa cavernosa. When a man gets an erection the blood flow is increased by the dilation of the arteries and blood vessels, this leads to the corpa cavernosa filling with blood and stiffening the penis.
Viagra is highly effective treatment for erectile dysfunction; it enables men to achieve healthy erections that last throughout intercourse. Millions of men every year are affected by erectile dysfunction, around one in ten, and many choose to order Viagra pills to enable them to continue their sex lives without the worry of erectile dysfunction.

However it has since become possible to order Viagra pills without a prescription, meaning men with erectile dysfunction are easily able to get treatment, without having to discuss it with a doctor, which can be embarrassing for many men.
A man with erectile dysfunction is unable to get an erection due to insufficient blood flow; this is caused by the constriction of the penile arteries and blood vessels. This constriction is caused by one of the body’s enzymes known as PDE5 which acts as a vasoconstrictor, causing the cells which line the arteries and blood vessels to contract.
Sildenfail Citrate for Erectile Dysfunction Treatment
Viagra is the name under which the sildenafil citrate drug is sold. Sildenafil citrate is a type of PDE5 inhibitor which deactivates the PDE5 enzyme rendering it inert. When the PDE5 enzyme is deactivated the blood vessels are then able to dilate which increases the blood flow to the corpa cavernosa, resulting in an erection. Sildenafil citrate no prescription offers should be looked at critically as they are often signs that a website is selling fake medication.
Viagra should be taken when the man is sexually aroused as the PDE5 enzyme will only be present for the drug to act on when the man is in a state of arousal or excitement. Viagra is a pill blue which is taken orally at least half an hour prior to intercourse, allowing the drug enough time to become effective.

With the availability of sildenafil citrate online it is now easier than ever for men to treat ED.
