Two unrelated, yearling Normandy bulls in a stud had 26 and 18% knobbed spermatozoa as well as other major sperm abnormalities. One bull was eliminated from the stud because of poor semen quality and growth. The other bull was maintained for additional semen evaluation, during which time the mean percentage of major sperm abnormalities decreased, indicating amelioration of a transient testicular degeneration.
