An elderly man in Colombia who deliberately took a high dose of Viagra had to undergo a penis amputation surgery after complaining of pain.

The doctors found that his penis was fractured, inflamed and started to show signs of gangrene. In order to prevent the gangrene from spreading to the rest of his body, the doctors decided to amputate his penis. “The patient showed bruising on the testicles and penis, was treated and is recovering well”, Dr Antonio Correa said.
