Erectile dysfunction, or impotence as it is sometimes known, affects around one in ten men worldwide. It can affect me of all ages though the condition is more prevalent in those over sixty; men aged sixty plus are four times more likely to be affected than men in their forties. Sildenafil 100mg pills are now available to help those who suffer from erectile dysfunction alleviate the condition. Men can get Viagra pills either from their doctor or from an approved online pharmacy.
Erectile dysfunction is the inability to achieve or maintain an erection either while aroused or during intercourse. This inability is caused by a lack of sufficient blood flow to the fleshy tissue that runs the length of the penis shaft, called the corpa cavernosa. When a man is sexually aroused or stimulated a series of molecular chemical reactions occur which lead to the dilation of the penile arteries and blood vessels. Erectile dysfunction occurs when these reactions do not occur correctly meaning that the blood vessels of the penis remain constricted, restricting blood flow. This blood vessel constriction is caused by the naturally occurring enzyme called phosphodiesterase type 5, or PDE5. The PDE5 enzyme acts on the cells lining the blood vessels causing them to contract, which in turn contracts the blood vessels themselves.
Oral Viagra for Discretely Treating Erectile Dysfunction
Sildenafil citrate, more commonly known as Viagra, is a PDE5 inhibitor which means it renders the enzyme inactive. With the enzyme deactivated the penile blood vessels are able to dilate, which increases blood flow to the corpa cavernosa, resulting in the stiffening and enlargement of the penis.
Sildenafil 100mg (or Viagra 100mg) tablets should be taken around half an hour prior to intended intercourse to give the drug time to absorb into the bloodstream and become effective. The man should also be sexually aroused when taking the treatment as the sildenafil will only react with the PDE5 which is only present during sexual arousal or stimulation.
Erectile dysfunction can be caused by a variety of factors. Health issues are responsible for the majority of erectile dysfunction cases, for example hypertension, diabetes and high cholesterol levels can be a cause. Psychological problems such as anxiety or depression can also bring about erectile dysfunction. Similarly drugs, both recreational and medicinal, can have erectile dysfunction as a side effect.
It is now possible for sufferers of erectile dysfunction to purchase sildenafil 100mg tablets, as well as lower dosages, online through specialised websites as well as through a pharmacy or doctor, making erectile dysfunction an easily treatable condition.
