Prostitution - the world's oldest profession - could be wiped out by the manufacture of sex robots, researchers have claimed.

In a study that would make C3PO blush, a study carried out in New Zealand claims that the sex tourism business will be transformed by the year 2050.

Published in the journal Futures, the study, titled "Robots, Men and Sex Tourism", written by management professor Ian Yeoman and sexologist Michelle Mars, describes an imaginary sex club in Amsterdam called Yub-Yum.

Sex tourists would visit Yub-Tum and pay €10,000 for massages, lap dances and straight sex from robotic sex workers.

New Zealand's Dominion Post reports the study as claiming that Yub-Yum would provide a rande of "sexual gods and goddesses of different ethnicities, body shapes, ages, languages and sexual features."

Mars and Yeoman claim the rise in sex robots would see cut out sexually transmitted diseases, although they make no reference to the outcome of any serious malfunctions.

Apparently clients would feel guilt free, as they have not cheated on their partner. The study concludes: "Robot sex is safer sex, free from the constraints, precautions and uncertainties of the real deal."
