cryptorchid

History and Etymology for cryptorchid

borrowed from the stem of New Latin cryptorchides, plural of cryptorchis (attested later) "having undescended testicles, a person with such a condition," from crypt- crypt- + -orchis, in monorchis monorchid

Note: As with monorchid, the stem of Greek órchis "testicle" was erroneously taken to be orchid-; cf. Greek krýpsorchis "undescended testicles," used by galen.
