A 2005 paper suggested leuprorelin as a possible treatment for autism ,  the hypothetical method of action being the now defunct hypothesis that autism is caused by mercury , with the additional unfounded assumption that mercury binds irreversibly to testosterone and therefore leuprorelin can help cure autism by lowering the testosterone levels and thereby mercury levels.  However, there is no scientifically valid or reliable research to show its effectiveness in treating autism.  This use has been termed the "Lupron protocol"  and Mark Geier , the proponent of the hypothesis, has frequently been barred from testifying in vaccine-autism related cases on the grounds of not being sufficiently expert in that particular issue    and has had his medical license revoked.  Medical experts have referred to Geier's claims as "junk science".
