Yes, the majority of people that try it. Then never come back to these forums. I dont remember seeing a lot of posts from ashton kutcher while he was on finasteride/dutasteride, but maybe I missed them. This forum is vastly skewed towards the negative although if you just google propecia the media in general is vastly skewed towards reporting horror stories and sensationalized negative stories of men going impotent permanently. They love Dr. irwig and his propecia help focused studies showing negative sides.
The real negative numbers are very small and the positives very high. Its a drug worth the risks which is why the FDA approved it. No other treatments for this condition. All drugs carry risk of unknown sides like neurosteroid thing we found later, but we all know these risks exist.
