Neurobehavioral models of pedophilia and child sexual offending suggest a pattern of temporal and in particular prefrontal disturbances leading to inappropriate behavioral control and subsequently an increased propensity to sexually offend against children. However, clear empirical evidence for such mechanisms is still missing. [...]
We compared behavioral performance and neural response patterns among three groups of men [...]: pedophiles with (...) and without (...) a history of hands-on sexual offences against children as well as healthy non-offending controls (...).
As compared to offending pedophiles, non-offending pedophiles exhibited superior inhibitory control [...] while no significant differences were found between pedophiles and healthy controls.
Data therefore suggest that heightened inhibition-related recruitment [...] is related to better inhibitory control in pedophiles who successfully avoid committing hands-on sexual offences against children.

A pedophilic disorder is recognized for its impairment to the individual and for the harm it may cause to others. Pedophilia is often considered a side issue and research into the nature of pedophilia is delayed in comparison to research into other psychiatric disorders.
However, with the increasing use of neuro-imaging techniques, such as functional and structural magnetic resonance imaging (sMRI, fMRI), together with neurop-sychological studies, we are increasing our knowledge of predisposing and accompanying factors contributing to pedophilia development.
At the same time, we are faced with methodological challenges, such as group differences between studies, including age, intelligence, and comorbidities, together with a lack of careful assessment and control of child sexual abuse.
Having this in mind, this review highlights the most important studies investigating pedophilia, with a strong emphasis on (neuro-) biological studies, combined with a brief explanation of research into normal human sexuality.
We focus on some of the recent theories on the etiology of pedophilia such as the concept of a general neuro-developmental disorder and/or alterations of structure and function in frontal, temporal, and limbic brain areas.
With this approach, we aim to not only provide an update and overview but also a framework for future research and to address one of the most significant questions of how pedophilia may be explained by neurobiological and developmental alterations.
