Why did the South Korean president's office order hundreds of Viagra pills?

An increasingly strange political scandal surrounding South Korean President Park Geun-hye has now left her office defending the purchase of hundreds of erectile dysfunction pills.

Park’s office on Wednesday confirmed revelations by an opposition lawmaker that it purchased about 360 Viagra pills and the generic version of the drug in December.

While the report has created a frenzy on the internet, Park’s office said the pills were bought to potentially treat altitude sickness for presidential aides and employees on Park’s May trips to Ethiopia, Uganda and Kenya, whose capitals are 1 to 2 kilometres above sea level.

None of the pills were used, said Jung Youn-kuk, spokesman of the presidential Blue House. South Korean doctors sometimes prescribe Viagra-style drugs to climbers because they are believed to be effective in preventing altitude sickness.

Park is now bracing for an impeachment push by opposition parties and some members of her own Saenuri Party amid allegations that she let a secretive confidante manipulate government affairs and amass an illicit fortune, a scandal critics say undermines the country’s democracy.
