epididymis 
1610, "fleshy mass at the back of the testicles" (jocularly called a taint), Mod.L., lit. "that which is on the testicles," from Gk. epididymis, a word probably coined by Gk. anatomist Herophilus (c.300 B.C.E.) from epi "on" + didymos "testicle," lit. "double, twofold" (adj.). "To save his Epididamies" [1652].
