According to the article, and it looks really sciencey and has approvals, so it must be true!
Why castrate ?
Castration is probably the most common procedure carried out across the world. Castration involves the removal or destruction of the testes or testicles and is carried out in order to stop the production of male hormones. Entire males tend to be more aggressive to both stock people and other animals, and can cause problems with unwanted breeding. They also generally produce lower quality meat. Castration eliminates all these problems.
Wow so, if I girlify myself, the quality of my meat improves too!
