Progesterex is a fictitious date rape drug that would purportedly cause sterilization. It is part of a hoax that began to circulate in 1999 via e-mail on the internet. No actual drug by this name or even with these properties exists, and no such incident has ever been documented or confirmed.[1] The most high profile person falling for the hoax was British MP Lynne Featherstone, who asked a question about the fake drug in Parliament.
