Viagra may cause hearing loss. What?

A recent study claims that heavy use of Viagra (and similar medications) can adversely affect your hearing.
According to the researchers: "men who self-reported hearing loss were more than twice as likely to have used a type of erectile dysfunction medication in the past"
With the incredible popularity of Viagra and other erectile dysfunction medication, I am thinking most users will risk the hearing loss.
Maybe they will just use it until they can't hear their mother-in-law.
