In ejaculated semen from highly fertile bulls, abnormal head forms constitute 5 to 20% of the total number of sperm heads, while even higher percentages are commonly found in ejaculates from bulls with certain types of reduced fertility. Intranuclear spaces and a granular appearance of the nuclear chromatin were the major abnormalities observed in a high percentage of spermatozoa from two infertile bulls (McCosker, 1969) . The organization of the DNA and nuclear proteins forming the
