"RapeX is an anti-rape female condom invented by a South African woman named Sonette Ehlers. As a former employee with the South African *lo** Transfusion Service, she treated many rape victims which served as her inspiration for creating this device. RapeX is a female condom that is inserted into the vagina much like a tampon. It is made of latex, like a normal condom, but it is lined with 'shafts of sharp, inward-facing barbs.' If a man attempts to rape a woman, once he penetrates the woman, the condom would attach itself to the penis and cause severe pain to the man during withdrawal.
Ideally, once the man is writhing on the floor, the woman would have enough time to escape the scene. In addition, the perpetrator would be unable to remove the female condom from his penis; he would have to get it surgically removed which would be a tell-tale sign to authorities and help in legal prosecution."
