'aspermatic' originates from Greek, specifically the word 'aspermatikos', where 'a-' meant 'without' and 'sperma' meant 'seed' (or 'sperm').

'aspermatic' changed from the Late/Medieval Latin form 'aspermaticus' (influenced by Greek 'aspermatikos') and eventually became the modern English adjective 'aspermatic'.

Initially, it meant 'without seed' (in a general or botanical sense), but over time it evolved into the current meaning of 'lacking spermatozoa; pertaining to aspermia' in medical usage.
