Weak Erections (also know as impotence or erectile dysfunction) is not a disease, but a secondary condition brought on by other, primary causes. It is a side effect, a symptom of something else. Thirty years ago, when men went to their doctors asking for help for erectile problems, they were told that there was no treatment because it was caused by aging, or it was all in their heads (psychological). A generation of research has been conducted in the intervening years.
