The film Cane Toads: An Unnatural History shows a male toad copulating with a female toad that had been run over by a car for eight hours. Necrophilic amplexus in frogs may occur because males will mount any pliable object the size of an adult female. If the mounted object is a live frog not appropriate for mating, it will vibrate its body or vocalise a call to be released. Dead frogs cannot do this, so they may be held for hours. The Amazonian frog Rhinella proboscidea sometimes practices what has been termed "functional necrophilia": a male grasps the corpse of a dead female and squeezes it until its oocytes are ejected before fertilising them. Treatment
Treatment for necrophilia is similar to that prescribed for most paraphilias. Besides advocating treatment of the associated psychopathology, there is little known on the treatment of necrophilia. There has not been a sufficient number of necrophiliacs to establish any effective treatments. However, based on the available data, clinicians are suggested to:

Determine whether or not a patient has necrophilia
Treat any psychopathology that is associated with necrophilia
Establish psycho-therapeutic rapport
Provide male patients with heightened sex drives with anti-androgens
Help patients find a normal sexual relationship
Help divert the necrophilic fantasies to a living object via desensitization

Case studies
Jeffrey Dahmer
Serial killer Jeffrey Dahmer (1960–1994) was known to perform oral sex or masturbate, or both, upon the corpses of his victims before dismembering them.
In unguarded, taped interviews with his defense attorney, Wendy Patrickus, Jeffrey Dahmer explicitly stated that he had sex with his victims before and after their deaths. He explained that he wanted to remain with the person as long as possible, preserving some of his victims selected organs, skeletal tissue and bones. Ted Bundy
Ted Bundy (1946–1989) was an American serial killer who raped and murdered at least 30 young women during the 1970s. He also confessed to participating in necrophilic acts, claiming to have chosen secluded disposal sites for his victims bodies specifically for post-mortem sexual intercourse. Karen Greenlee
In 1987, Karen Greenlee gave a detailed interview called “The Unrepentant Necrophile” for Jim Mortons (edited by Adam Parafrey) book Apocalypse Culture. In this interview, she stated that she had a preference for younger men and was attracted to the smell of blood and death. She considered necrophilia an addiction. The interview was held in her apartment, which was apparently a small studio filled with books, necrophilic drawings, and satanic adornments. She also had written a confession letter in which she claimed to have abused 20–40 male corpses. Dennis Nilsen
Dennis Nilsen (1945–2018) was a Scottish serial killer who had developed an association between death and intimacy, later finding posing as a corpse a source of sexual arousal. In 1978, Nilsen committed his first murder and had intercourse with the victims corpse, keeping the body for months before disposal. Nilsen was reported to have sexually abused the corpses of various victims until his arrest.
