The typical response of the "prostatic" deferent duct has been characterized by an initial tonic-phasic "mixed" activity, immediately followed by a phasic activity marked by rapid strong "twitch-like" contractions. These latter may suggest the presence of a mechanism recruiting muscle cells, as if the vas deferens has a pace-maker action which is morphologically quite similar to the "twitch" that can be highlighted by electric stimulation.
