A Mexican man who reportedly took a sexual stimulant used on bulls spent three days with a painful erection before surgeons were forced to operate to cure the condition.
The man reportedly bought the medicine, known as "bull viagra", in the city of Veracruz before he was hospitalised in the city of Reynosa.
He told doctors he had chosen to take the medication to prepare for a date with a 30-year-old woman.
The doctors who treated him said: "He was hospitalised in the Specialised Hospital 270 of the city of Reynosa, he had taken a sexual stimulant which he had bought in Veracruz, used by farmers in that region to invigorate bulls for insemination."
