A new study finds that about one-third of men reported sidestepping a health-care professional when buying erectile dysfunction drugs. Those tablets bought on the Internet aren't necessarily cheaper than the real thing, but they do allow buyers to avoid the embarrassment associated with asking for this type of drug.
But, doctors say erectile dysfunction can be an early warning sign of heart disease or diabetes, so patients need to see a medical professional.
The study is published in the International Journal of Clinical Practice.
