THE LONG-TERM USE OF CYPROTERONE-ACETATE IN PEDOPHILIA - A CASE-STUDY

This investigation reports the long-term use of the antiandrogen cyproterone acetate (CPA) in a pedophile, who was studied continuously over 38 months. Measures of sexual arousal, serum testosterone, and gonodatrophen levels were significantly reduced by the drug as compared with placebo and no treatment; prolactin levels were significantly elevated. Some workers have observed that long-term administration of CPA (more than one year, which was then discontinued) produced enduring (in some cases apparently permanent) antilibidinal effects; however, in the case described, within three weeks of stopping the drug, all measures had returned to pretrial levels. The importance of continuous long-term monitoring in sex offenders receiving an antiandrogen is discussed.
