Penis amputated after man, 66, overdoses on viagra 'to impress new girlfriend'

A 66-year-old Colombian man is reported to have had his penis amputated after "enthusiastically" overdosing on the erectile dysfunction drug Viagra.

The man, who asked to remain anonymous, admitted himself to hospital in the small town of Gigante, after sustaining a constant erection for several days, according to Colombia Reports.

He had apparently overdosed on the drug in an attempt to impress his new girlfriend.

Concerned medics referred him to a hospital with more ample medical facilities in Neiva, where he was diagnosed with a penile fracture and swelling, with symptoms of gangrene, Diario del Huila reports.

The amputation was carried out to prevent further inflammation and gangrene from spreading to other parts of his body, the newspaper added.

"The patient had bruising in the testicles and penis, was treated and is recovering well," Dr Antonio Correa told La Nacion.

Viagra - which is also known as Sildenafil - works by relaxing muscles in the walls of the blood vessels.

Chest pains and irregular heartbeat are some of the symptoms associated with a Viagra overdose.

Painful, prolonged erections - known as priapism - hives, nausea and sudden vision and hearing loss are also possible.

"Priapism is a medical emergency - you should seek immediate medical assistance if you think you have it.
