Progesterex is a date-rape drug used to sterilize women.

  Rumors have been circulating on the web that Progesterex is a "horse sterilizer" being used by rapists...that results in sterilization.

  But there is no truth to this rumor. In fact, Progesterex does not even exist. Even the name Progesterex is a rumor.

  Sometimes veterinarians use a progestin/estrogen combination to temporarily prevent a mare from going into heat...but not for sterilization.
