'anteprostatic' originates from Latin prefix 'ante-' meaning 'before' and from Medieval Latin 'prostaticus', ultimately from Greek 'prostátēs' meaning 'one who stands before (prostate)'.

'prostátēs' (Greek) became Medieval Latin 'prostata'/'prostaticus', which produced the English adjective 'prostatic'; the Latin prefix 'ante-' was then combined with 'prostatic' to form 'anteprostatic' in modern medical English.

Initially 'prostátēs' meant 'one who stands before' in Greek; over time the term named the prostate gland and related adjectives became anatomical, so 'anteprostatic' now specifically means 'located in front of the prostate'.
