However, a number of the most oft-quoted studies, such as Miletski, were not published in peer-reviewed journals.There have been several significant modern books, from Masters (1962) to Beetz (2002); "The phenomenon of sexual contact with animals is starting to lose its taboo: it is appearing more often in scholarly publications, and the public are being confronted with it, too.[...] Sexual contact with animals – in the form of bestiality or zoophilia – needs to be discussed more openly and investigated in more detail by scholars working in disciplines such as animal ethics, animal behavior, anthrozoology, psychology, mental health, sociology, and the law." More recently, research has engaged three further directions – the speculation that at least some animals seem to enjoy a zoophilic relationship assuming sadism is not present, and can form an affectionate bond.Zoosadism specifically is one member of the Macdonald triad of precursors to sociopathic behavior.which he defined as a sexual attraction to animal skin or fur.Exclusive desire for animals rather than humans is considered a rare paraphilia, and sufferers often have other paraphilias The first detailed studies of zoophilia date from prior to 1910.Peer reviewed research into zoophilia in its own right started around 1960."Bestiosexuality" was discussed briefly by Allen (1979), but never became widely established.
Zoophilia has been partly discussed by several sciences: Psychology (the study of the human mind), sexology (a relatively new discipline primarily studying human sexuality), ethology (the study of animal behavior), and anthrozoology (the study of human-animal interactions and bonds).The percentage of males who reported sexual interactions with animals in 1974 was 4.9% (1948: 8.3%), and in females in 1974 was 1.9% (1953: 3.6%).Miletski believes this is not due to a reduction in interest but merely a reduction in opportunity.The nature of animal minds, animal mental processes and structures, and animal self-awareness, perception, emotion in animals, and "map of the world", are studied within animal cognition and also explored within various specialized branches of neuroscience such as neuroethology.In the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), zoophilia is placed in the classification "other specified paraphilic disorder" Zoophilia may also be covered to some degree by other fields such as ethics, philosophy, law, animal rights and animal welfare.
