The development of fetishism is a very complex process, with biological aspects suggesting that fetishism may be related to temporal lobe lesions; psychosocial factors suggesting that fetishism is related to the patient’s childhood psychosexual developmental disorder; self-psychological defence mechanisms suggesting that sexual impulses are transferred to appropriate objects, such as those used by the opposite sex, through displacement, believing that the object fetishised has symbolic meaning and is a direct and implicit drive; and conditioned reflex theory suggesting that fetishism is formed when sexually aroused couples are combined with unrelated stimuli through conditioning mechanisms.
