No basic differences in size (mean \ m=+-\ s.d. for at least 300 spermatozoa), shape and ultrastructure of the spermatozoa of fallow deer were detected (1) in comparison to other artiodactyls, (2) between different fallow bucks, and (3) between different months of the fertile season. The total length of the normal spermatozoon was 67\m=.\2 \ m=+-\ 1\m=.\2 \g=m\m. The flat, paddl e\x=req-\ shaped head was 8\m=.\2\ m=+-\0\m=.\3 \g=m\mlong, 4\m=.\4\m=+-\0\m=.\2 \g=m\m for the greatest width,

The tail measurements were 13\m=.\7\ m=+-\0\m=.\3 \ g=m\ m for the midpiece, 0\m=.\5\ m=+-\0\m=.\1 \g=m\m for the diameter of the midpiece, 42\m=.\6 \ m=+-\ 0\m=.\9 \g=m\m for the principal piece, and 2\m=.\7\ m=+-\0\m=.\6 \g=m\m for the endpiece. Spermatozoa with abnormalities such as cytoplasmic remnants and droplets, bent and coiled tails, as well as microcephalic forms were observed.
