title: An intravasal non-occlusive contraceptive device in rats.
abstract: An implantable miniature biogalvanic cell was developed to kill the spermatozoa in the vas deferens by an electric current. Experiments in vitro and in vivo showed that a combination of aluminum/silver electrodes connected with platinum wires with the vas deferens fluid as n electrolyte is effective in killing spermatozoa. Female rats paired with males having biogalvanic devices in the vas deferens, which remained patent, did not produce any young.
