It's been done, with child molesters who've been chemically castrated through the use of high potency Depo-Provera (medroxy progesterone) injections.

It reduces the rate at which offenders reoffend, but there are still those who do. They tend to find other means, such as foreign objects, to penetrate their victims, and the level of violence for those who continue to offend tends to go up.

Rape is as much about sex as domestic violence is about boxing.

I've never looked at a domestic violence victim and though "I bet her boyfriend really got the urge to box with her and she turned him down."

Gilda, if I may? Chemical castration must produce high levels of resentment, and if a hormone has proven to be violent, it's estrogen. The research is available, I'm just stating what I claim to "know".
If one's willing to do this thing and doesn't have their necessary tool, I am not surprized that they'd resort to others. Sometimes the cure is worse than the disease...ok, probably not here, don't get me wrong: I also feel anger towards rapists.
As a species we make outrageous mistakes and then run around trying to cover our asses. I think it can't be done and wonder how we can be so wrong. There were prior days when judgment was swifter and less exotic, and yes, I'm advocating (gasp!) surgical castration or the death penalty for repeaters.
The wrongness of this view might be revealed, unless it's not.

Quoted out of context I find this hilarious. I hope I'm not the only one.

All I know about castration is that if you have an aggressive male mammal... cut off it's balls. If it doesn't become more laid back then you must've left some of the balls.

Sure, this is one of the criticisms of chemical castration, that the frustration produced can cause an escalation in the violence.

My point, however, was that many sex offenders continue to offend even when they cannot become aroused. Even with the sexual element removed, the desire remains.

Well, to begin with, medroxyprogesterone, the drug used to chemically castrate, is a synthetic progestin, not an estrogen. The research I've read on estrogen usage in physical males is that it increases the intensity of both positive and negative emotions, but decreases aggressiveness, especially when combined with androgen agonists. Aggression and libido are, in general, linked to androgen levels, not estrogen. Estrogen helps regulate moods, female reproduction, and is essential for maintaining bone and muscle health; I've never heard of any direct link to aggressive tendencies, and what I've read seems to indicate the opposite effect.

I think that people confuse the act with the motive. In the case of rape, a person is violated and robbed of their inalienable right/choice. Also, we need to think about what sex is or should be: sex is or should be about making an informed decision and feeling empower to make that decision; rape robs one of making an informed decision and the empowerment one should have or feel in making such a decision. That aside, robbery too is about power and perhaps greed. Robbery, like rape, takes awake one un-guarded self. In turn, this allows the robber or rapist feel powerful.

I hope not, too. But did you look it up?:expressionless:

progesterone?

The first part of your statement is viewed as true 'out on the farm". I'm wondering about the second part, since a competent veterinarian would've found them both. Beyond that, I'm worried about (oh, good goddess!) those who would imagine what they're feeling doesn't mean something. Since the females have been left to protect the offspring they might have the means, come who will. C'mon!
