Due to its personal nature, the subject has been taboo for a long period of time, and is the stuff of many urban legends. Since the 1930s, folk remedies have been advertised widely for the condition. The introduction of sildenafil (Viagra®) in the 1990s caused a second wave of public attention, propelled in part by heavy advertising.
