Hi, Thanks for writing in. Eunuch is a term where a person has gender identity problems with respect to their external genitalia. These people usually have feminine body characteristics with a normal or abnormal female genitalia and most of them are born this way with chromosomal abnormalities. Some people assume eunuchoid features by taking injections of male and female sex hormones and by castration. In your situation, if your wife has been developing male body characteristics, she must be examined by an endocrinologist and a psychiatrist to know her physiological and mental sexual orientation. Then she can take counseling and medication to reverse the changes under medical supervision. This is done over a period of months. If she wants to change her gender through gender reassignment surgery, there are options and legal procedures involved. Such treatment is given only with patient consent. Hope this helps.
