It has been estimated that at least one in ten men suffer with frequent and long-standing erection problems (erectile dysfunction); this number increases with age, and it is thought that 50% of men between 70 and 74 years may suffer from erectile dysfunction. Viagra has been heralded as one of the greatest developments in the treatment of impotence, so much so that it is often known as the 'magic blue pill'. It works by relaxing the blood vessels that supply blood to the penis; which in turn allows more blood to flow into the penis, resulting in a harder and more prolonged erection. Viagra promotes penile erection only in response to sexual stimulation and so unwanted erections will not be caused in the absence of stimulation.
