YouTube video by Anne Truong MD explaining how Botox can be used in urology to relax penile smooth muscle. The speaker states that Botox blocks a stress chemical (norepinephrine), turning off the sympathetic 'fight-or-flight' signal in smooth muscle, forcing relaxation, widening the vessel and allowing increased blood flow—presented as a mechanism to improve erections.

Questions this video answers

Norepinephrine (the 'fight-or-flight' chemical).
