This is again just a theory based on an observation, but I’ve read a study on this site that said finasteride attaches itself to 5ar producing cells in a persistent way. It doesn’t say permanent so I choose to consider it means a long time, whatever that could be (maybe a few years ?).
That would suppose it does eventually comes off the 5ar producing cells. Maybe that’s one of the reason some people see improvements with time and many have good enough improvements that they consider themselves recovered around the 4-6 years mark.
I don’t have any numbers to draw any statistics on the percentage that do improve enough that they consider themselves recovered.
I know I’m within this range and my PFS is pretty much gone, with still some lingering symptoms. I can say I can now live a normal life. I know half a dozen others in that range that consider they can now go on with their life and I’ve heard of other people that also know half a dozen to a dozen that go on having normal lives, some with mild symptoms remaining. Add that up, plus the stories on this thread and you’ll see the numbers of recoveries is significant.
Until some doctor or someone comes up with a sure way to cure this, there’s no guarantees. There’s hope, that’s for sure !
