During my 8-year stretch on finasteride I had gradually increasing symptoms. Things were getting worse but very slowly. At the end of the period the biggest issues were lower libido, weaker erections and (!) shrunken penis. People who have this symptom would know this but let me clarify. I am not referring to smaller erections here but to smaller, thinner and lighter penis in the flaccid state, which is evidence for tissue atrophy. This effect has of course been confirmed in many rat studies. I also had other symptoms that did not bother me such as watery semen and lack of morning erections. The realization that my penis had shrunk was quite shocking when I finally figured it out and that was a major reason for my decision to quit finasteride. In other words, and this is very important, I had developed penile atrophy while on finasteride without having PFS. It must have happened gradually during the last couple of years because in the early years on finasteride I don’t think I had it. That issue has not improved at all since I stopped finasteride. In fact, I think it has gotten worse.
Yes, the second time I took it I took it for one month but I got knocked down after the first pill. I continued taking it hoping it would go away and also tried to taper off but nothing changed.
Prior to that experience I had stopped finasteride one more time a couple of years earlier for around 3 months. I had no issues while being off it or after I went back on it at the time.
