Cyproterone acetate has the strongest evidence for reducing sexual arousal, while findings on medroxyprogesterone acetate have been mixed.Gonadotropin-releasing hormone analogues such as leuprorelin (Lupron), which last longer and have fewer side-effects, are also used to reduce libido, as are selective serotonin reuptake inhibitors. The evidence for these alternatives is more limited and mostly based on open trials and case studies. All of these treatments, commonly referred to as "chemical castration", are often used in conjunction with cognitive behavioral therapy. According to the Association for the Treatment of Sexual Abusers, when treating child molesters, "anti-androgen treatment should be coupled with appropriate monitoring and counseling within a comprehensive treatment plan." These drugs may have side-effects, such as weight gain, breast development, liver damage and osteoporosis.Historically, surgical castration was used to lower sex drive by reducing testosterone. The emergence of pharmacological methods of adjusting testosterone has made it largely obsolete, because they are similarly effective and less invasive. It is still occasionally performed in Germany, the Czech Republic, Switzerland, and a few U.S. states. Non-randomized studies have reported that surgical castration reduces recidivism in contact sex offenders. The Association for the Treatment of Sexual Abusers opposes surgical castration and the Council of Europe works to bring the practice to an end in Eastern European countries where it is still applied through the courts. Epidemiology
Pedophilia and child molestation
The prevalence of pedophilia in the general population is not known, but is estimated to be lower than 5% among adult men.
Much of the direct action classified as anti-pedophile involves demonstrations against sex offenders, against pedophiles advocating for the legalization of sexual activity between adults and children, and against Internet users who solicit sex from minors.High-profile media attention to pedophilia has led to incidents of moral panic, particularly following reports of pedophilia associated with Satanic ritual abuse and day care sex abuse. Instances of vigilantism have also been reported in response to public attention on convicted or suspected child sex offenders. In 2000, following a media campaign of "naming and shaming" suspected pedophiles in the UK, hundreds of residents took to the streets in protest against suspected pedophiles, eventually escalating to violent conduct requiring police intervention.
