A man from southern Colombia had to have his penis amputated after he allegedly overdosed on Viagra to impress his girlfriend, The Daily Mail reports.

The 66-year-old man from Gigante, Colombia, whose name has not been released, told a local newspaper that he intentionally overdosed on the erectile dysfunction medicine.

He then is said to have suffered an erection for several days before being forced to seek medical advice.

When he sought medical help, doctors in Gigante referred the man to a medical facility in Neiva, where medical staff noted that the man's penis was inflamed and fractured.

They informed the patient his only option was amputation so the inflammation and gangrene would stop spreading to other parts of his body.

As a result of the incident, Neiva hospital issued a warning for men to not use penis enhancing drugs or erectile dysfunction medication without prescription from their doctors. 

Earlier this week, a Yemeni man died of a Viagra overdose as he prepared to sleep with his bride on their first day as a married couple.

The 25-year-old Yemeni man dosed up on five Viagra pills at one time which killed him, according to Yemini Arabic Language daily newspapwer Okaz Al Youm.

Viagra contains the ingredient sildenafil citrate, which works by relaxing muscles in the walls of blood vessels.
