A eunuch is a man who has been castrated, typically early in life, and often serves specific roles in society, such as in royal courts or as guardians of women's quarters. Historically, eunuchs were employed for their perceived loyalty and inability to father children, which made them trusted servants or advisors. In various cultures, they held significant power and influence, often in positions related to governance or administration. The practice of creating eunuchs has declined significantly in modern times.
