Where I live high doses of cyproterone acetate have been used for chemical castration (>200mg), but at these levels there's a chance of developing benign brain tumours, so they try not to do this. I think zolodex is also used in this manner, and it's more effective since it's a long-lasting implant rather than a daily pill. In both cases they're not 100% effective, different people respond differently.
