A South African doctor has invented a female condom that is lined with teeth-like hooks in a bid to deter rapists.
Dr Sonnet Ehlers, who sold her home and car to develop the condom known as Rape-aXe in 2005, is handing them out at World Cup venues, and after the trial period they will be available for 2 dollars each.
The latex condom, which a woman can insert like a tampon, has jagged rows of hooks on the inside, and they work by attaching to a man's penis during penetration.
And once attached it can only be removed by a doctor, and Dr Ehlers hopes it will make it easy for the authorities to make arrests.
"It hurts, he cannot pee and walk when it's on. If he tries to remove it, it will clasp even tighter... however, it doesn't break the skin, and there's no danger of fluid exposure," News.com.au quoted her as saying.
"I consulted engineers, gynaecologists and psychologists to help in the design and make sure it was safe," she said.
But the Rape-aXe condom has met with criticism from some, who feel it will only make women vulnerable to more violence from men trapped by the device.
Dr Ehlers plans to distribute 30,000 free devices under supervision during the World Cup period.
