Viagra for impotence / erectile dysfunction causes
Start
Viagra started off as a rather disappointing treatment for angina but doctors began to notice that patients were very reluctant to stop taking it, even after surgery had dealt with any angina problems. One by one the Viagra users confessed that a wonderful thing had happened after Viagra: their sex life had dramatically improved. Many of these Viagra patients had medical reasons why they may have had erectile problems, ranging from the impotence (erectile dysfunction) caused by blood pressure drugs, heart problems and general to health. Doctors are trained to report all unexpected side effects, and the reports on these positive Viagra “side effects” kept pouring in.
But was Viagra safe to use? Doctors reported that 70% were helped by Viagra to a better sex life, while 16% got headaches, 10% severely, others had other symptoms such as indigestion or a blue tinge to their sight.
These diamond shaped Viagra pills cost around $12 for a single tablet. The effect soon wears off so the demand can only be guessed at. If just 2 million men decide to use Viagra regularly (twice a week) then the US demand alone will be around 200 million tablets a year or up to $2 billion in market value. But that’s just the US.. British private clinics are charging around double the US price per Viagra tablet (£16) but are reluctant to do so without a full diagnostic screen costing around £300-400.
And then people wondered about Viagra for women, so-called female Viagra (new drugs for female sexual dysfunction). Although there is little evidence that Viagra helps women who take it themselves to improve their love-life, Viagra may help pregnant women with placental insufficiency, by improving blood supply to the uterus. Some doctors also think it may have a slight effect in assisting conception in some forms of infertility - perhaps for the same reason.
