I cant say if we are tiny minorty unless we can diagnose. Its clear to we have so many sufferers who dont know this site or cant speak even simple english or dont know whats going on their body. Nontheless i know at least 10 pfs victims who dont join forum. We know merck make profit 400 million dollar per year thanks to propecia, so with a simple calculation 300k-350k people use finasteride right now. If we say %2 get side effects (infact it is lie) then we have at least 6-7k pfs sufferers.
But dont forget its not a infectious disease which infect air, sea or blood. Its directly due to finasteride, so dont expect 100 billion victims at short or long term.
