Abstract:

The aim of the work to show the morphology of the testis of Adult Sudanese duck (Anas platyrhynchos). The adult duck testes were two bean-shaped‚ large and soft‚ the left testis was usually higher in position and larger in size than the right one. The testis was active during cold weather with the mean diameter of the seminiferous tubules being 124 µm in the duck. It was less active during the hot season with the mean diameter of the seminiferous tubules being 134 µm in the duck. The non-breeding season seemed to be characterized by a decline in the spermatogenic activity only and not by complete spermatogenesis. The mean volume of left testis in the adult duck was 9.12 cm’. They exceeded those of the right testes by 8%; the relative volume of the components remained essentially the same in both testes. The seminiferous tubules formed 90% of the volume of the testes in duck.
