How might someone “fix” E.D.?

“The first real breakthrough in the treatment of erectile dysfunction came in 1983. Prior to that time, it was thought that erectile dysfunction -- the inability to achieve an erection -- was primarily mental.

That concept came crashing down at the 1983 American Urological Association meeting in Las Vegas when Dr. Giles Brindley injected his penis with the drug phentolamine. Following the injection, Brindley appeared on stage and dropped his pants to display one of the first drug-induced erections to the incredulous audience of urologists.”
