For Androgenetic Alopecia "I have PFS (Post-Finasteride Syndrome). I cannot sustain an erection during sex, suffer from genital anesthesia and/or numbness, have muted/blocked/pleasureless orgasms when I masturbate, and suffer from brain fog, memory loss, and thinking at times. I have low testosterone, extremely high FSH, low cortisol, low vitamin D, adrenal issues, and pituitary problems as a result of being on Propecia on and off for years. I've been off of Propecia for a year. Although I've had shockwave therapy to remove penile scar tissue and improve nerve damage and had testosterone replacement therapy, my sexual functioning and cognitive issues persist. Oh! And I became infertile on Propecia too. Fortunately, I had enough sperm left to have a baby with my wife via IVF. Stay away from this toxic and poisonous medication! It will potentially destroy your life."

For Androgenetic Alopecia "At the tender age of 25, I noticed that my hair was beginning to thin. Not wanting to look like my dad or brother, I got a prescription for Propecia. So far, it's been working. In fact, if I miss a dosage, I'll notice little bits of my hair fall into my keyboard or the pages of a book I'm reading! Yes, this medication is expensive. My insurance won't cover it at all. (Funny that they cover Viagra, though). The only side effect is that I do notice a slight decrease in my sex drive - but honestly that's probably good. Keeps me out of trouble."

For Androgenetic Alopecia "Complete brain fog, worse than anything you can imagine, literally can't get out of bed because of the brain damage that this drug induced on me. I feel completely, literally detached from the world now, not to mention even the less serious it caused, ED, no libido, head pressure, complete cognitive shift. Feel like I'm in a whole different world. NEVER TOUCH this drug EVER, EVER, EVER, unless you're old and have nothing else to lose and don't care about life anymore. I would trade this with ANY other disease just for my brain function to come back again. I feel like I'm in a coma, it's absolutely frightful, every day 24/7, it never leaves. Sexual sides are a joke compared to this."

For Androgenetic Alopecia "I took 5 pills from April 2-6. Over the course of those 5 days, I had worsening symptoms of brain fog, headaches, sleeplessness, suicidal ideation, ED/impotence, loss of libido, increased fat mass, and muscle weakness that didn't dissipate for a month and a half. Even now (July), I still have increased fat mass, increased tissue on the breast, peripheral edema (mild), and difficulty (mild) with erections. I'm not as focused or driven due to ongoing sleep difficulties (mild/moderate) and the intensity of these effects. Every day, I regret taking this drug. I took this drug without researching any side effects, I really regret not looking into possible side effects. Please be aware that the consequences could be extremely negative and persistent."

For Androgenetic Alopecia "Do not use it! This is a very dangerous product. After 4 weeks of using it, I had a total loss of libido and almost became impotent. I have now stopped for three weeks and am still not back to normal. This product is a chemical castration! I don't understand how this product is available on the market. Use other alternatives such as Regaine. Do not use, do not use, do not use!!!!! Giving a 1 rating is overrated."

For Androgenetic Alopecia "Don't take this drug. I used it for a few months, and it killed my libido. I did get some noticeable hair regrowth during that time, so at least that worked. It became very hard to get an erection, and I became completely disinterested in sex. I've read accounts that some people never regained their libido and suffered lasting erectile dysfunction. This is not natural. Your libido is part of who you are, and so is hair loss. Be a man and accept the loss of your hair as part of who you were meant to be."

For Androgenetic Alopecia "After 2 days on Propecia, I started to feel heavy brain fog. I didn't know about this side effect, but I found out on the internet that it is a common side. I can tell you that feeling is worse than the sexual side effects. I wish no one to feel that horrible feeling."

For Androgenetic Alopecia "Took this drug for 2 months in the year 2011, it has ruined my life. I have all sexual side effects, and the physical side effect, penis shrinkage, is the worst. It's been years since I quit the medicine, and I am still suffering with nasty side effects."
