It is first being researched for animals for veterinary purposes, but they intend to also get it approved for humans (for cancer patients).

Here is an article on them:

Wow! Single-shot (chemical) castration at a projected cost of $50 a pop! The mind, as they say, boggles. I wonder how safe it will be? I doubt it'll be freely available, but not terribly hard to come by either. If the product pans out I won't be surprised if there's an increase in the number of eunuchs, voluntary and otherwise. I mean, if it really will be that easy.........

I also wonder how many days it will be before someone posts a story based on this news flash.

I know I can't wait. That would be way better than a lifetime of Depo-Provera shots.
