Researchers from all over the world have begun investigating many questions surrounding pedophilia - including what makes a pedophile, and how to identify one. In the laboratory-setting, those researchers have come to a fascinating conclusion: that pedophilia may be a predisposition, so deeply rooted, that it could be a form of sexual orientation.
In the United States, Canada and Germany, researchers have concluded that pedophilia does not stem from psychological influences early in life, such as an early childhood trauma, as previously thought. Instead, an attraction to prepubescent children is likely the result of brain chemistry. Or, as James Cantor, a researcher in Toronto stated, "the only explanation is a physiological one."
