Repeated Exposure to ED Ads May Cause ED

Andrew J. Vickers, PhD, DPhil

Posted: 05/01/2012

A new study has found that repeated exposure to phosphodiesterase inhibitor advertising may lead to erectile dysfunction, especially in young men. The researchers studied 1231 men aged 18-72 years, asking about television viewing habits and sexual function. Using the watching of televised baseball games as a surrogate for exposure to Viagra advertising, they found statistically significant associations with erectile dysfunction, even after adjustment for age, comorbidity, and marital status in a multivariable model.

According to senior author Matthew Watson, Professor of Urologic Epidemiology at Duke University, the study is the first to provide direct evidence that advertising can have a direct negative impact on men's health. "It makes sense that repeatedly watching older adults cuddling and looking meaningfully at each other would be a bit of a turn-off," said Watson. "We now have solid data that this is indeed the case."

Statistician Jürgen Witt agreed that the data were interesting but cautioned against overinterpretation. He has a particular interest in surrogate endpoints in epidemiology, and he pointed out that they are prone to confounding. Witt argues that the study findings might simply reflect a classic "couch potato" effect and insists that "experimental data are the only way forward."

As such, the study team are preparing an R01 project in which participants will be exposed to 3 hours of back-to-back Viagra commercials and then directly questioned about libido. Watson is upbeat about his chances: "We intend to oversample minorities, meaning that we will be the first study ever to assess ethnic differences and diversity issues."

None of the manufacturers of phosphodiesterase inhibitors commented directly on the study, but one released a statement pointing out that, while they would do nothing to stifle the free flow of academic ideas, "the effects of that little blue pill on the mental well-being of millions of American men cannot seriously be questioned."
