Bestiality in Forensically Committed Sexual Offenders: A Case Series.

Although bestiality has occurred since prehistoric times, it remains a poorly understood aspect of human sexuality. Prevalence studies in the mid-20th century suggested that bestiality was a relatively common phenomenon. Since that time, researchers have studied bestiality among specific populations, including self-identified "zoophiles" and inmates who report a history of bestiality. Findings from inmate research suggest that bestiality may represent a risk factor for future interpersonal violence. This study presents a case series of bestiality among sexual offenders committed under forensic commitment schemes. The case series demonstrates the range of animal partners, sexual acts, and comorbid paraphilic and nonparaphilic diagnoses in individuals who report a history of bestiality. In addition, it helps clarify potential motivations for sex with animals and how such motivations may influence the forensic psychiatric assessment of offenders who have sex with animals.
