'acyesis' originates from Greek, specifically the word 'akyēsis,' where 'a-' meant 'not' and 'kyēsis' meant 'pregnancy.'

'akyēsis' transformed into the Latin word 'acyesis,' and eventually became the modern English word 'acyesis.'

Initially, it meant 'not pregnant,' but over time it evolved into its current meaning of 'sterility.'
