Origin of testis

1675–85; <Latin: “witness, spectator, testicle.” The sense “male gonad” is a loan translation from Greek parastátēs “bystander, supporter (at law),” in medical usage (in the dual and plural) “the (pair of) glands lying side by side, the testicles” (equivalent to para- para-1 + the combining form -statēs, from histánai “to make stand.”) Compare Greek prostátēs “one who stands in front, ruler,” in medical usage “the gland lying in front, the prostate
