'anaphrodisia' originates from Greek, specifically the prefix 'an-' meaning 'without' and 'Aphrodisia' referring to sexual pleasure (from Aphrodite, the Greek goddess of love).

'anaphrodisia' was formed in modern medical English by combining the Greek prefix 'an-' with 'aphrodisia', and eventually became the modern English term 'anaphrodisia'.

Initially, it meant 'absence of sexual pleasure or desire', and this meaning has remained consistent in modern usage.
