The tight underwear heats the wearer up and is an effective form of contraception for men who want to avoid getting their partner pregnant.

The garment, which is traditionally worn by sportsmen, lifts testicles close to the body while raising their temperature and lowering sperm count. The jockstrap is most effective when worn for 15 hours a day.

A study of 72 men in France found that all would recommend the underwear to a friend as it spared their partner from the pill.

Lead author Professor Jeanne Perrin, from Aix-Marseille University, said: "We know men use jockstraps for contraception already, but the ones developed for this are proven to provide sufficient heat to prevent pregnancy.

"While some men still think these pants are a bit strange, or that they are funny, many want to use them."
