One thing that frightens me about discussions on this topic is how quickly people want to physically hurt a sex offender with the justification that it will stop that offender's behaviour. The evidence from studies show this isn't actually effective at stopping offenders from their behaviour.
The Marshall et al. (1991) paper I cited above includes a section on physical interventions. This includes:
- stereotaxic ablation of central nervous system centers
In layman's terms, this is brain surgery to try to remove the area believed to be in charge of sexual behaviour (the ventromedial nucleus of the hypothalamus). The results are sickening.
A summary of some of the doctors involved in 1973 show that they performed this surgery on 22 patients, including 1 homosexual and 1 alcoholic. The fact that they did this for a homosexual and an alcoholic speaks volumes. 16 patients had molested boys or girls, 3 were exhibitionists, and 1 was characterised as a hypersexual nondeviant.
The majority of the molesters didn't change as a result of the brain surgery. The hypersexual nondeviant died as a result of the operation. The homosexual reported no relief from his homosexual tendencies (I guess he wanted to change), and the alcoholic received no benefit. One of the exhibitionists lost all sexual interest, which is just sad.
In Europe, there have been at least 2055 men castrated according to published reports from 1959 - 1973. Recidivism data based on official records reveals remarkably low rates of sexual reoffending (0 - 7.4%).
The figures are misleading though, because in the early days of castration, homosexuals were castrated as well. The data includes homosexual "offences". Furthermore, the published data doesn't state what type of offender was being castrated, so there's no solid data on how many of each type of sex offender was castrated.
A report in 1981 of 39 castrated offenders, which included rapists, child molesters, and homosexuals, showed that 46% still masturabated or had intercourse. All manner of disabling side-effects also showed up as a result of the castration. A 1968 report gave a zero recidivism rate in terms of sexual offending among the Danish castrates, but 33% were subsequently convicted for a nonsex crime, while only 20% of a matched group of noncastrated rapists subsequently reoffended in a nonsexual way.
In other words, just because they were castrated doesn't mean they didn't go on to commit more crimes. In fact, they seemed to commit more crimes than before, albeit of a non-sexual nature. I don't see that as a win, do you?
- the administration of pharmacologic agents thought to function as sexual antagonists
In layman's terms, antiandrogens are drugs that are supposed to prevent or inhibit the biologic effects of androgens - male sex hormones - on normally responsive tissues in the body. One of the goals is to try to somehow reprogramme the brain to respond to acceptable erotic stimuli while simultaneously decreasing the response to unacceptable stimuli.
Those used in studies are:
estrogen treatment (That's right - they turn 'em feminine!)
neuroleptics
medroxyprogesterone acetate (MPA)
cyproterone acetate (CPA)
The first two treatments aren't used anymore because they didn't produce the desired results.
MPA in conjunction with cognitive/behaviour therapy seems to produce the desired results in certain offenders. However, there are studies citing sociopathic pedophiles, whose testosterone levels fell to very low levels, displayed no corresponding reduction in sexual arousal.
CPA with cognitive/behaviour therapy actually shows the most promise. It caused some pedophiles to become erotically aroused at stimuli showing consenting heterosexual interactions, while at the same time producing greater inhibition to pedophilic stimuli.
On the other hand, some studies show that while CPA may actually reduce a person’s awareness of arousal to deviant cues and consequently reduces sexually deviant behavior, the actual degree of arousal remains unchanged.

Right. Given this evidence, what do we think now, Specktra-ites?
