Late Middle English: from Latin testiculus, diminutive of testis 'a witness' (i.e. to virility).

The ancient Romans felt that a man's testicles testified that he was male. They formed the word testiculus from Latin testis ‘witness’, the source also of attest (late 16th century); detest (Late Middle English) which originally meant to denounce; protest (Late Middle English); testify (Late Middle English); and intestate (Late Middle English) ‘without a witnessed will’. The testicles were the ‘witnesses’ of the man's virility.
