Eunuchized is an uncommon word that refers to being castrated. However, there are several synonyms that can be used instead of eunuchized. These include emasculated, gelded, neutered, and emaciated. Each of these synonyms carries a slightly different connotation. Emasculated implies a loss of power or masculinity, while gelded is specifically used in reference to animals that have been castrated. Neutered is a more clinical term that encompasses both males and females who have been sterilized. Emaciated refers to a person or animal who is thin to the point of emaciation, and therefore, may be used metaphorically to refer to a lack of vitality or vigor.
