Short YouTube video by Anne Truong MD titled 'The Accidental Discovery of Viagra' explaining how men in phase one clinical trials reported unexpected improvements in erections. It links these observations to the nitric oxide pathway and phosphodiesterase enzymes, which led researchers to investigate the drug’s effects beyond its original indication.

The amazing story back then was a lot of the men were saying, hey, I don't know about my chest pain, but I wake up every boy with better. In these phase one trials, they were doing with several men in their clinical center, and that's where they backed into thinking, wait a second. I'm hearing about this Science of that involves the pathway that controls this nitric oxide release called phosphodiesterase.
