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 "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 "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 "I've decided to write this review for Propecia because I didn't take this drug for 9 years because of the horror reviews online, even though my hair loss was causing me intense anxiety every day. I didn't have the courage to take it until my brother started taking it. It truly does give you relief knowing that someone you know closely is taking it. Once he started taking it, I told myself it is time I take the plunge. At least if the worst happens, we'll experience it together. I've been taking it for 6 months now with little to 0 side effects. Before taking it, I was concerned about permanent penile shrinkage, ED, and watery semen. ED is definitely not an issue in the slightest. Penile shrinkage, I don't think so at all, but I'm not positive since I didn't measure before and after. If I thought there was penile shrinkage, I would stop. My GF hasn't noticed a difference. It's possible my semen is slightly more watery, but that's it."

For Androgenetic Alopecia "This stuff is poison. I only took a small dose, and I'm still suffering 3 years later. Causes depression and erection and libido problems."
