Effects of cyproterone acetate on sexual arousal patterns of pedophiles

Abstract

The antiandrogen treatment of sexual offenders has been shown to reduce the recidivism rate. The mechanism of action has been assumed to be through asexualization with its secondary effects on sexual behavior. This study shows that the mechanism may be more complex and may involve a differential effect on sexual arousal patterns. Treatment responses may differ in high and low plasma testosterone groups.

Changes in Sexual Arousal as Measured by Penile Plethysmography in Men with Pedophilic Sexual Interest

“…PPT is currently the “gold standard” for the objective measurement of sexual arousal, based on the association between penile tumescence and subjective sexual arousal [21] (for a detailed description, see Firestone et al. [22] and http://www.limestonetech.com).…”

“…PPT is currently the "gold standard" for the objective measurement of sexual arousal, based on the association between penile tumescence and subjective sexual arousal [21] (for a detailed description, see Firestone et al [22] and http://www .limestonetech.com). During PPT measurement of sexual arousal, the man is seated alone in a testing room with an elastic band-type sensor (Indium-Gallium strain gauge, Limestone Technologies Inc., Odessa, ON, Canada) behind the head of his penis while a standardized set of sexual stimuli is presented via an Epson PowerLite 50c.…”

Antiandrogen treatment for sexual disorders: Guidelines for establishing a standard of care

“…However, the methodological problems of these studies do not allow for definitive conclusions to be drawn about the real efficacy of antiandrogen therapy. Nonetheless, patients treated with antiandrogen therapy generally report favorable results, involving a decrease in sexual desire and arousal and a decrease in sexual fantasizing (Bradford & Pawlak, 1993b;Federoff et al, 1992;Meyer et al, 1992).…”

A Biopsychosocial Model of Hypersexual Disorder/Sexual Addiction

“…The exact role of testosterone in hypersexuality is currently not known. However, agents that lower testosterone have been found to be effective in the treatment of intense urges in paraphilias (Bradford & Pawalak, 1993) and hence, may have applicability in hypersexual disorder (Codispoti, 2008).…”
