Erectile dysfunction is the distressing condition defined by a man’s inability to achieve or maintain an erection. Over the centuries there have been many proposed methods of curing and reversing this condition but not until the advancement of modern medicine and research was a successful treatment discovered. The discovery and creation of Viagra medication and other similar drugs has been revolutionary in the treatment of erectile dysfunction. The discovery of these drugs has meant that erectile dysfunction has become an easily treatable condition with a Viagra prescription.
Erectile dysfunction affects around one in ten males worldwide. It predominantly affects older males with men over sixty being most affected, but it also occurs among all other age groups. Impotency, as the condition is sometimes known, can be an embarrassing and distressing affliction. There can be a number of reasons why men experience erectile dysfunction, it can be the side effect of drugs, either recreational or medicinal, it can be the result of an existing condition, such as high blood pressure, or it can be caused by psychological disorders like depression. One or more of these factors can result in an insufficient flow of blood to the penis, preventing a man from getting or sustaining an erection.

An erection is caused by sexual arousal by sexual stimulation either mental or physical or both. When this occurs the blood vessels in the muscular flesh of the penis dilate and fill with blood, causing the penis to stiffen. Erectile dysfunction occurs when there is insufficient blood flow within the penis. Viagra medication contains an ingredient called sildenafil citrate which is a PDE5 inhibitor. PDE5 is a chemical in the blood which causes blood vessels to be constricted and its presence hinders the blood flow to the penis. Viagra medication restricts the PDE5 from acting on the blood vessels and so increases blood flow; meaning the man can get and keep an erection.
The Viagra medication comes in pill form and is ingested orally. It usually takes around half an hour for Viagra medications to take effect and the erection produced usually lasts for a couple of hours, though sometimes longer. Viagra should be taken when the man is sexually aroused as the active ingredient requires chemicals that are only present while aroused for it to work effectively. It is common place for doctors to recommend Viagra medication as treatment for people who suffer from erectile dysfunction. There are also several online pharmacies that offer Viagra no prescription required.
