I have erectile dysfunction now and I am 26. I want to start finasteride, so what will happen to me?

Pre-existing erectile dysfunction is more common than most people think. The statistics are something like 20% of men in their 20s, 30% of men in their 30s, 40% of men in their 40s, 50% of men of men in their 50s.  Many men don’t like to recognize that they might have ED, so it is easier to blame Finasteride, so for this reason, it is difficult to tell which causes what. The risk of making it worse is about 4% as the general statistics remain the same, i believe.
