Autoerotic asphyxial deaths: analysis of nineteen fatalities in Alberta, 1978 to 1989.

This paper presents an unusual form of sexual (masturbatory) activity and brings this unusual cause of death to wider medical attention and understanding. All 19 cases of autoerotic asphyxial death that occurred between 1978 and 1989 in the province of Alberta, Canada were reviewed. The fatal victim of autoerotic asphyxia is typically a single male aged 15 to 29 years. Autoerotic sexual activity is typically performed in isolation; often there is evidence of repetitive practice. The accidental death usually results when the "safety" mechanism designed to alleviate neck compression fails. Often the first sign of the activity (usually a surprise to family and friends) is death itself. Physicians who are alert to the practice may suggest counselling when patients present with sexual concerns, unusual marks around the neck or evidence of abrasions to limbs suggesting bondage or other masochistic practices.
