Sterilization began in America in 1887, when the superintendent of the Cincinnati Sanitarium published the first public recommendation for the sterilization of criminals, both as a punishment and a way to prevent further crime. Authorities used the same method to sterilize male criminals that farmers used on their male animals not selected for breeding--castration. Castration was the preferred method used to sterilize male criminal offenders until 1899, when vasectomy was adopted because it was more practical.

I wounder of the Burdizzo was invented back then??

It would be nice if castration magically made a violent man docile and well-behaved, like it seems to do to animals.

I thought castration was that effect, docil and calmness, and if they castrated men as a punishment, like they did here in Southern Calif until the 1960's, then it should have worked right?
