All participants displayed a pedophilic sexual arousal pattern at the time of their first PPT. To test for change, we compared initial PPT results with subsequent PPT results measured at least 6 months later.</p> </sec> <sec id="jsm12488-sec-0004" sec-type="section"> <title>Main Outcome Measure</title> <p>Sexual arousal was assessed using PPT by measuring change in penile circumference induced by the presentation of standardized sexual audio stimuli.</p> </sec> <sec id="jsm12488-sec-0005" sec-type="section"> <title>Results</title> <p>Approximately half of the sample (n = 21) displayed a change in PPT results. This change was characterized by a significant decrease of sexual arousal in response to pedophilic (child) stimuli and a significant increase of sexual arousal in response to nonpedophilic (adult) stimuli. No differences between sexual interest changers (ICs) and nonchangers (NC) were found for demographic data or for length of time between assessments. However, between‐group comparisons revealed that ICs had significantly lower pedophilic indices at the initial assessment than NCs.</p> </sec> <sec id="jsm12488-sec-0006" sec-type="section"> <title>Conclusions</title> <p>Results from the current study indicate that relative pedophilic interest, as defined by increase in penile circumference in response to nonpedophilic stimuli as measured by PPT, changed in about 50% of men diagnosed with pedophilia who also had initial pedophilic PPT sexual responses. This represents a significant challenge to the hypothesis that sexual interest in men with pedophilia is unchangeable and should be the focus of future studies. <bold>Müller K, Curry S, Ranger R, Briken P, Bradford J, and Fedoroff JP.
