Chemical castration using LHRH agonists reduces circulating testosterone to very low levels, and also results in very low levels of recidivism despite the strong psychological factors that contribute to sexual offending... Chemical castration reduces recidivism effectively when offered to sexual offenders within the context of simultaneous comprehensive psychotherapeutic treatment.' - PubMed
