"During the ninth century, a Persian physician recommended inserting into the cervix paper wound tightly into the shape of a probe, tied with a string and smeared with ginger water (Manisoff, 1973). Also, during certain rituals, the Maori people of New Zealand put small pebbles into women’s vaginas to make them “sterile as stones” (Himes, 1963). Similarly, Casanova, who claimed to have invented almost everything that has to do with sex, soaked a small gold ball in an alkaline solution and inserted it in his lover’s vagina (Suitters, 1967)."
