Notes:
The ejaculate of a Friesian bull contained three abnormalities: rolled, crested, and knobbed spermatozoa. The rolled form had marked lateral curvature of the head, occasionally forming a complete tube. All three forms were of testicular origin and it is likely that the first two were developmentally related.
