ABSTRACT
Animal research has shown that aggressive behavior is accompanied by physiological changes, including changes in blood chemistry due to the secretion of andrenocorticotropic hormones. To understand the organic treatments, a fundamental understanding of the biobehavioral basis of male sexual behavior and, specifically, sexual aggression is required. Despite considerable research, knowledge in both the identification and the treatment of the violent sexual offender is deficient. Some studies have also sought a link between violent sexual offenders and testosterone. Plasma-testosterone levels for the rapists and child-molester controls were within normal limits. The group of rapists who were the most violent did, however, have significantly higher mean plasma-testosterone levels than did the normals. The most significant organic treatment of the violent sexual offender is the use of antiandrogen medication, specifically cyproterone acetate, in addition to the hormonal treatment approach using medroxyprogesterone acetate. Castration is the removal of the testes and can be an effective way of reducing recidivism in violent sexual offenders.
