Eunuch

From Wikipedia:

"A eunuch is a human male whose testicles have either been removed or are non-functional. The earliest records for intentional castration to produce eunuchs are from the Sumerian city of Lagash in the 21st century B.C. Over the millennia since, they have performed a wide variety of functions in many different cultures such as military commanders, singers, religious specialists, government officials, and even guardians of women."

Brilliant. That. Is. A. Brilliant. Idea, and should be implemented immediately.
