Progesterex - Progesterex is a fictitious date rape drug. 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. Furthermore, no sterilization pill for horses exists. Sterilization is done via gelding of stallions. Mares are usually left unaltered. In addition to this vet students do not have access to drugs. Drugs can only be perscribed by a qualified, registered veterinarian (Member of the Royal Collage of Veterinary Surgeons - MRCVS - in UK). On 18 April 2006 UK Member of Parliament Lynne Featherstone submitted a Written Question to the Home Secretary on whether the Home Office had calculated the number of date rape incidences that had been connected with Progesterex. Home Office Minister Paul Goggins replied that the drug did not exist [1] [2]
