Eunuchry is a term that is no longer widely used in the English language. However, it can be replaced by various synonyms such as castration, emasculation, or neutering. All these synonyms are usually used to describe the process of removing or disabling the testicles in males, resulting in the loss of their ability to reproduce or experience sexual desire. In addition, the term 'eunuchry' can also be substituted with the phrase 'lack of sexual potency' or 'impotence.' It's important to note that these terms are often utilized in medical settings, and may not be considered appropriate for everyday usage.
