I have been using Propecia (for 6 years) w/excellent results as far as hair growth and stopping hair loss. I recently have had a sudden erectile problem in the last 4 weeks or so. I noticed in the last few months less sperm but my erection was fine. Now I feel like I am in trouble because I have a hard time keeping my erection. I am immediately stoppung use and have read that after 6 weeks, the side effects are reversable but have also heard that some side effects are permanent. I do not know what to believe. Maybe the men who have irreversable side effects have other problems that is causing this. For me I know it is the Propecia causing this but I am wondering the erectile dysfunction will be permanent or will rever 
se itself. Is there anything I can do to speed up the recovery process? Help!
First of all… You are posting in the “Recovery” section, and from the sounds of it, you are the opposite as we speak. Now hopefully within the next 2 weeks-2 months maybe it can sometimes take, you will recover and be just fine.
Read all over this site for ideas…
Stay calm.
Use it or lose it!
Eat healthy.
Excercise
If you don’t recover within two months, and you know there is a problem, try a PCT treatment right away. Just like all the steroid users do. It is part of protocol. I would have definitely done it if I had only knew.
I experienced the same unexpected side effects after about 7 years of using propecia. For about two weeks and a couple of days I had no desire for sex, masturbating or porn and could barely get an erection.
After this time though I started to watch porn and actually got turned on and it has been very good for me the last couple of days so give it some time and try to relax. I know i was fucking freaking out when this happened so wait it out for a bit.
