The first victim evidenced hypoxyphilia through his repetitive self-suspensions by the neck. He developed a romantic attachment to his tractor, even giving it a name; the authors suggest the altered mental state and perceptual distortions engendered by hypoxia were the primary effects he sought in his self-hangings. In the second case, the victim died of positional asphyxiation by chest compression. He engaged in sexual bondage and cross-dressing, and died when accidentally pinned to the ground under a shovel after he intentionally suspended himself by the ankles. These cases were characterized by escape mechanisms and a lack of suicidal ideation, both of which are essential features of accidental autoerotic asphyxiation. Other reported autoerotic deaths have involved the use of machinery, usually household or homemade electrical devices that cause electrocution. Individuals who engage in dangerous autoerotic practices can be treated with antiandrogenic medication to reduce the intensity of their sexual drives. 2 figures and 17 references
