More than 20 million men around the world use it regularly. In the U.S., one out of every five men over 40 has tried it. An average of nine Viagra pills are dispensed every second. What more could anyone possibly need to know about Viagra? Plenty. Because for all its ubiquity, Viagra is surprisingly misunderstood. We all know what it does -- and what it helps men do -- but beyond that, how much does anyone really know about the Viagra experience? "It has the name recognition of Coke and Nike," says Harin Padma-Nathan, clinical professor of urology at the University of Southern California Keck School of medicine.

But in the U.S., an estimated 34% of all men ages 40 to 70 -- about 20 million men -- suffer from some significant level of erectile dysfunction. Most of them, about 80%, never seek treatment.
