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 Greekprostátēs “one who stands in front, ruler,” in medical usage “the gland lying in front, the prostate”

Word Origin and History for testis
n.
(plural testes), 1704, from Latin testis "testicle," usually regarded as a special application of testis "witness" (see testament), presumably because it "bears witness" to virility (cf. Greek parastates, literally "one that stands by;" and French slang témoins, literally "witnesses"). But Buck thinks Greek parastatai "testicles" has been wrongly associated with the legal sense of parastates "supporter, defender" and suggests instead parastatai in the sense of twin "supporting pillars, props of a mast," etc. Walde, meanwhile, suggests a connection between testis and testa "pot, shell, etc."
