The present report is a review of all 554 papers published on Medline on pedophilia. The first discussion is the history of the disorder from ancient Greece to the present time, especially the influence of the liberal country of the Netherlands, the North American Man-Boy Love Association, and the sexual crisis in the Catholic Church. One important question is the relationship between homosexual pedophilia and adult homosexuality. Evidence for and against this relationship is presented. Next discussed are the characteristics of the victim and the long lasting serious effects of sexual abuse. Laboratory correlations are included, especially phallometric tests in order to objectively measure the physical responses to sexual stimuli. Electrophysiological and radiographic tests are also mentioned, including electroencephalography, computed tomography, magnetic resonance imaging, and positron emission tomography scans. An important section is the characterization of pedophiles with emphasis on their frequent previous sexual abuse, their past, their present, and their anticipated future. The final topic is treatment of this disorder with surgery, medication, behavioral therapy and the combination of medication and behavioral therapy.
