      No sperm are present in the seminal vesicles, though the preelongation spermatogenic stages are unaffected.

      (Crowley, 1998)

      Ether-anesthetized adults exhibit leg-shaking phenotype.

      (Crowley, 1997.7.14)

      Ether-induced leg shaking, and male sterility due to immotile sperm.
