Summary
The process of cell division during spermatogenesis in Taenia hydatigena followed the general pattern reported by Rybicka (1966) for other cestodes. Sixty-four spermatozoa were formed from each primary spermatogonium after a series of five nuclear divisions. During spermiogenesis, changes in the organisation of sperm tail cytoplasm were evident with four distinct regions along the length of the spermatozoon being distinguishable. The axoneme which was normally single in each sperm tail, had the typical 9 plus 1 structure found in platyhelminths. Nuclear material in the mature spermatozoon was arranged spirally around the axoneme.
