Serbian men are swapping their prize cows to get a bigger penis.

The bizarre exchange was revealed by the country's top plastic surgeon Srecko Djordjevic who said dozens of farmers obsessed with the size of their penis had traded in their prize cows for larger members.

He said: "The size of a man's member seems to play a big role in our society and the price of the operation, around £400, is almost exactly what a good cow is worth - so farmers are choosing to swap a cow if it means a bigger penis."

The urologist, who is based in the central town of Kragujevac, told the news agency Sina that the only problem had been that some farmers had unrealistic ideas of what they could get for their money.

He said: "Some of them want to add 10 centimetres and that is just not possible - at least not for just one cow."
