Pedophillia (or paedophillia in the UK) is a psychological disorder in which an adult or older adolescent experiences a sexual preference for prepubescent children. The causes of pedophillia are currently unknown and research is ongoing. Someone who is diagnosed with pedophillia is referred to as a pedophile. Although the majority of those diagnosed as being pedophiles are male it is estimated that up to 5 to 20% of child sexual offences were commited by females.
There is currently no definative cure for pedophillia (as with many psychological disorders), and treatment is primarilly aimed at trying to prevent the expression pedophillic behaviour and reducing the incidence of child sexual abuse. The success rates of the therapies that are currently available for the disorder remain low.
