To cut a long story short, I have been using Propecia for 7 years and have stopped for good for a week now after discovering this forum. Last year, I also developed the symptoms of MS. I had tests done, which (I was surprised but none the less pleased to find) found no evidence of demylenation. They did discover a growth spur on my spine in my neck, which was apparantly putting pressure on the spinal cord, and which they concluded was causing the symptoms. I was relieved, but I’m still not entirely convinced. Apart from some periodic dizziness, I’ve been free of those symptoms for almost a year (they cleared up after about three months). Surely the growth spur is always there, it doesn’t retract? But anyway, I am now reading this thread today, and I wish I’d discovered it last year. I am also grateful to Alex for looking into this, as I do believe he’s on to something with this.
With all due respect, I do fundamentally disagree with Alex though on one point that he made. From the the accounts that all the members appear to have given on this site, it appears to me that the problems with impotence are a side effect of either temporary or permanantly reduced testosterone levels. If all impotence was a side effect of demylenation, then all the members on here who reported impotence as a side effect would also be reporting the other symptoms of demylenation e.g dizziness and nausea, loss of movement in limbs, muscle cramps and spasms, slurred speech, feelings of disco-ordination, tingling and numbness etc, and they don’t. It seems to me that when you take into account the other commonly reported side effects of Propecia usage e.g testicular shrinkage, gynecomastia, reduced ejaculate, penile shrikage, a damage or inhibition to testosterone production is the primary cause of the Impotence.
It’s an important point to make, because it’s one thing for the forum members to be dealing with the health problems that they have as it is, without believing that they have MS as well, which at the end of the day is a permanantly dibilitating and life threatening illness.
