Eunuch

Eunuch

eu·nuch | \ˈyü-nək,  -nik\
1: a castrated man placed in charge of a harem or employed as a chamberlain in a palace
2: a man or boy deprived of the testes or external genitals
3: one that lacks virility or power 

Old English, via Latin eunuchus from Greek eunoukhos, literally ‘bedroom guard’, from eunē ‘bed’ + a second element related to ekhein ‘to hold’.

Eunuch seems to be the accepted umbrella term for all castrates, even though eunuch history is deep and varied.  Eunuchs existed in China and India, Greece and Rome, the Middle East and Africa, eastern and western europe. Slavery and forced genital amputations were common, but not ubiquitous.  The term probably also applies to men like me, the chemically castrated, but also to M2E trans people and maybe to many older men whose natural testosterone levels have dropped sufficiently to cause andropause.

Critical Eunuch Studies  A subfield of gender studies, concerned with understanding masculinities through the lens of the eunuch:  a non binary critical identity from which gender, sexuality, society and politics can be viewed and understood uniquely.
