Head‐to‐head agglutinates of bull spermatozoa, produced by heterophil agglutinins in human sera, revealed the same phenomenon as described for human spermatozoa: When rotating on the plate all agglutinates rotated counterclockwise. The interpretation lends further support to the hypothesis that the normal direction of the propagation of the overall helix‐like tail wave is counterclockwise (ie, opposite the direction of the axonemal arms), corresponding to a clockwise shape of the wave (from base to tip) at a given instant. Heteroagglutinins may be a useful tool in physioanatomical studies of spermatozoa.
