A doctor in South Africa has designed what she claims is a new female "condom with teeth" aimed at preventing rape.
Dr Sonnet Ehlers has created the female condom, called Rape-aXe, some 40 years after she met a devastated rape victim who was like "a breathing corpse".
"She looked at me and said, 'If only I had teeth down there'," Ehlers, who was a 20-year-old medical researcher at the time, recalled in an interview with 'CNN'.
"I promised her I'd do something to help people like her one day."
Now, 40 years on, Rape-Axe is born.
The condom has jagged teeth-like hooks that latch onto a man's penis during penetration. Once it lodges, only a doctor can remove it -- a procedure Ehlers hopes will be done with authorities on standby to make arrest.
"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," the doctor said.
Dr Ehlers has been distributing 30,000 free condoms under supervision during the World Cup period.
"I consulted engineers, gynecologists and psychologists to help in the design and make sure it was safe," she said.
