in a more detailed study on bull spermatozoa during epididymal maturation , we observed that pme activity was low in testicular spermatozoa , increased in spermatozoa from caput epididymidis to a maximum of 1.29 pmol/mg protein , and progressively decreased to a very low level ( 0.06 pmol/mg protein ) in spermatozoa from cauda epididymidis .
