Hello, I took this fucking shit : Proscar 1,25 mg for only 5 days, and in the 5th day I started to have side effects as haedache, anxiety, sleepness, no energy, brain fog, pain in the testiles and abdomen, no erectile functions, low libido, watery sperm./// I stopped to use this medications 4 weeks ago, some og these side effects dissaeparce but still have no good erection and watery sperm – I am wonder that only 5 pills are enough to create sofucking problem… I thought hat after 1-2 weeks I recover to my good old times, but I have stiill have problems… Erection is nly a liitle better… 
Unfortunately I had the same problem. It didn’t take long before I lost erections, penile sensation, morning erections, and worst of all libido. Also had the brain fog with unusual day dreaming episodes. Suddenly didn’t have interest in hugging, kissing, or smelling my girlfriend (or any other woman). I stopped the drug and after two weeks began improving. I noticed in the short time I used Propecia I also lost my oily skin (a good thing) and my “male” musky smell (also from the sebaceous glands). I started getting that back smell after a couple of weeks. In my case, hopefully not yours, my side effects have persisted now for 12 months. My initial improvements disappeared (like others on this forum). I can get partial erections if directly stimulated. Penile numbness still there and minimal libido. I noticed that without libido your motivation is diminished. It is a form of chemical castration which is what we do to cats and dogs to kill some of their spunky motivation (they become nice and docile). I also noticed it diminished my interest in creativity! I am hopeful though since others on the board have had recoveries after a year, some 4 years, others 7 years. If you were on it a short time however, many recover in 3 months or so which is what my urologist said. Sadly not for me. Balding AND impotent destroys confidence especially with women. Good if you like to stay single!
