How Viagra changed the way the world thought and talked about sex
Created as a treatment for high blood pressure, Viagra has revolutionised the treatment of erectile dysfunction in the past 20 years, and has been credited with stiffening tribal support during the war in Afghanistan

In the annals of the frustrating fight against impotence, men have ingested rhino horn dust, performed elaborate dances, employed vacuum hydraulics, and chanted what one historian called “protective spells” that went like this: “Get excited! Get excited! Get an erection!”
But none of those remedies were as successful – or crazy – as what one doctor did at a urological conference in 1983. Before presenting his research to hundreds of doctors, Giles Brindley injected – yes, injected – his penis with papaverine (which caused an erection). On stage, he dropped his trousers to demonstrate the results.
“There was not a sound in the room,” a urologist recalled in a scientific journal. “Everyone had stopped breathing.”

Viagra, approved 20 years ago on March 27, 1998, became a pharmaceutical and cultural phenomenon at a very odd moment – amid former US President Bill Clinton’s sex scandal involving intern Monica Lewinsky, when one of Clinton’s fiercest and oldest political enemies, Bob Dole, the conservative Republican senator from Kansas became an evangelist for the drug.
