'aspermatism' originates from New Latin, specifically the word 'aspermatismus', ultimately from Ancient Greek elements 'a-' meaning 'without' and 'sperma' meaning 'seed' or 'sperm'.

'aspermatism' changed from the New Latin word 'aspermatismus' and eventually became the modern English word 'aspermatism'.

Initially it meant 'lack of seed' in the broad, literal sense; over time it evolved into the specific medical meaning 'absence of sperm in semen'.
