Erectile dysfunction can be a distressing and worrying condition. Erectile dysfunction is when a man is incapable of getting or sustaining an erection when sexually aroused or during sex.
Erectile dysfunction or impotency can damage a man’s self esteem, provoke feelings of inadequacy or lead to depression. It affects millions of men worldwide, with men of all ages suffering from it.
The physical and chemical processes that result in an erection are complex and there are various factors which can affect a man’s ability to get an erection. Psychological issues like stress or depression can lead to impotency as can health problems such as hypertension or high cholesterol. Drugs can also prevent erections; nicotine and alcohol are known causes of erectile dysfunction. Although erectile dysfunction can happen at any age, the prevalence for the condition is among older men. Men over sixty are around four times more likely to experience erectile dysfunction than men in their forties. Every sale of Viagra should be carefully monitored by a licensed doctor.

Viagra is a medication designed to treat erectile dysfunction. Viagra has been freely available for years and has helped millions of men combat erectile dysfunction. It can be purchased through prescription with a doctor as well as from pharmacies and online, though Viagra costs may vary dependant on the source.
An erection occurs when a man is sexually aroused or stimulated. Chemical reactions cause the blood vessels in the penis to dilate which increases blood flow. The muscular tissues along the shaft of the penis, called the corpa cavernosa, fill with flood, stiffening the penis. For men who suffer from erectile dysfunction, the blood vessels remain constricted due to the presence of PDE5 a naturally occurring vasoconstrictor. Viagra is a PDE5 inhibitor which prevents the PDE5 from constricting the blood vessels, this allows them to dilate, increasing the blood flow and stiffening the penile tissue.
Viagra should be taken while the man is sexually aroused as the chemicals required for Viagra to work effectively are absent otherwise. Viagra comes as a blue pill which is taken orally prior to intercourse. It is taken around half an hour before intercourse as the pill needs time to absorb into the bloodstream and take effect. Many men choose to buy Viagra samples in order to make sure that the pill works for them. An erection produced by Viagra will last for around two hours, though in some cases it can last up to four.
Erectile dysfunction is now an easily manageable condition. Viagra costs are different worldwide, but it is readily available and enables men to get and keep erections effectively. Delivery of Viagra is safe and discreet and can arrive within one business day.
