random sample in sexual research, but pointed out that when Paul Gebhard, Kinsey's research successor, removed prison samples from the figures, he found the figures were not significantly changed. By 1974, the farm population in the USA had declined by 80 percent compared with 1940, reducing the opportunity to live with animals; Hunt's 1974 study suggests that these demographic changes led to a significant change in reported occurrences of bestiality. 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. Nancy Friday's 1973 book on female sexuality, My Secret Garden, comprised around 190 fantasies from different women; of these, 23 involve zoophilic activity. In one study, psychiatric patients were found to have a statistically significant higher prevalence rate (55 percent) of reported bestiality, both actual sexual contacts (45 percent) and sexual fantasy (30 percent) than the control groups of medical in-patients (10 percent) and psychiatric staff (15 percent). Crépault and Couture (1980) reported that 5.3 percent of the men they surveyed had fantasized about sexual activity with an animal during heterosexual intercourse. In a 2014 study, 3% of women and 2.2% of men reported fantasies about having sex with an animal. A 1982 study suggested that 7.5 percent of 186 university students had interacted sexually with an animal. A 2021 review estimated zoophilic behavior occurs in 2% of the general population. Perspectives on zoophilia Research perspectives Zoophilia has been 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). 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" ("paraphilias not otherwise specified" in the DSM-III and IV). The World Health Organization takes the same position, listing a sexual preference for animals in its ICD -10 as "other disorder of sexual preference". In the DSM-5, it rises to the level of a diagnosable disorder only when accompanied by distress or interference with normal functioning. Zoophilia may be covered to some degree by other fields such as ethics, philosophy, law, animal rights and animal welfare. It may also be touched
