Abstract: Sperm Abnormality in Two Infertile Bulls Sperm abnormality was observed in two Holstein bulls in the course of routine investigations of infertility. One bull suffered from oligo-asthenospermia. Its spermogramme showed a marked percentage increase in microcephalic, pycnotic spermatozoa, of which the tail coiled around the head. From the spermogramme, this case was diagnosed as arrested spermiogenesis. The pedigree of this bull suggested the intervention of some unfavorable factors. The other case was accompanied by asthenospermia. In the spermogramme of this case there was a remarkable increase in the percentage of corkscrew-sperms, accompanied by a gradual decline in sperm motility.
