An anti-rape device is one of a variety of devices invented for the purpose of preventing or deterring rape. The first such devices were the chastity belts of the 15th century. Although a number of devices have been proposed, none of them are in commercial production as of 2017[update].
Some of the most well-known anti-rape devices were proposed in South Africa, a country with a high incidence of rape and a low rate of successful convictions. South African activists argue that the legal system has not been effective in preventing or reducing rape and other violent acts against women.
Rape is, however, not only a third world issue but also affects developed countries. According to a 2001 World Health Organization study, 20% of women worldwide had been victims of rape or attempted rape at least once in their lives. According to figures from a 2011 report from the Centers for Disease Control and Prevention, one in five women in America are victims of sexual assault. More than 40% of these victims are children, reporting they were first raped before they were 18 years old.
A number of concepts have been proposed for physical deterrents to rape, and although they attracted media attention, none of them have gone into production.
An early prototypical anti-rape female tampon was invented in late 2000 by Jaap Haumann, a South African man, for the purpose of preventing rape. Haumann's device was designed to resemble a tampon for ease of insertion, and consisted of a hard cylindrical plastic core containing a tensioned spring blade primed to slice when pressed against by the tip of a penis. Following activation, a portion of the tip of the penis would be removed, in effect performing a minor penectomy.
An anti-rape female condom using a different design was invented by Sonette Ehlers, a South African woman. Ehlers was motivated to create it while working as a blood technician with the South African Blood Transfusion Service, during which time she met many rape victims. Ehler mentioned that she was inspired to create RAPEX (later renamed to Rape-aXe) when a patient who had been raped stated, "If only I had teeth down there," suggesting the myth of the vagina dentata. Initially called RapeX, the name was changed in 2006 upon discovering that RAPEX is also an EU warning system against dangerous goods on the market.
