Anti libido drugs can be effective in reducing sexual desire and performance but they don't necessarily eradicate the risk to children.
There are numerous ways to sexually abuse without being able to achieve an errection.
Child sexual abuse is a hideous crime with far reaching consequences for the victim. It is considered by most people to be the worst crime imaginable and it understandably provokes a great deal of emotion.
Having worked with child sexual offenders in MH in the community, secure units and prisons; I don't think these dolls are the way to go at all.
In my opinion, and I know this will probably be an unpopular view - as a society we need to acknowledge that people who have a sexual interest in children are numerous and from all walks of life. There are far too many children being abused to consider this a complete aberration of behaviour.
'Hang them' or throw away the key is an instinctive response to the horror of it but there are too many. They are parents, children, siblings, Dr's, teachers, Police officers ..Every profession you can think of as well as people who don't work, registered disabled etc.
Often, sexual interest in and subsequent abuse of children is like a lot of criminal activity- something that happens in degrees over a period of time. It only comes to the attention of MH services/criminal justice system when the most serious offence has been committed.
We can't intervene at the point that someone has started to think about it or started to view images of child abuse because it is the worst thing you could possibly admit to anyone and it necessarily leads to safeguarding reports. So it drives people further underground and further and further into on-line abusive activity where they may meet like minded individuals who excuse/normalise it and it escalates further.
There are some offenders who I suspect may have stopped at a certain point if appropriate psychological help had been available but of course they can't ask for help because it triggers a sequence of events. I don't know what a suitable solution would be but what we do now is not working.
And for posters thinking that child sex offenders get their 'just desserts' in prison - 'nonces' (prison term) are hated by prisoners in general population but they very rarely have contact. Most child sex offenders are housed in vulnerable prisoner wings with other sexual offenders (child or adult sexual offenders) and 'grasses'.
There are even some dedicated prisons for sexual offenders now.
