Microscopic Features of Gonadally Inactive Testis of Khaki Campbell Duck (Anas platyrhynchos domesticus) in Bangladesh

The microscopic features of the testis were studied in gonadally inactive Khaki Campbell duck (Anas platyrhynchos domesticus) in Bangladesh. The study was conducted in the Department of Anatomy & Histology, Bangladesh Agricultural University, Mymensingh. Five adult healthy birds of one-year-old were used for this study. The testes were collected immediately after ethical killing of the birds for histological observations. The collected tissue samples were then processed and stained with Hematoxylene & Eosin (H & E) stain for histological observations. The seminiferous tubules showed considerable involution with cessation of spermatogenesis. The basal lamina of the seminiferous tubules was irregular in outline and was invaginated into the germinal epithelium in the form of finger-like plicae or folds. Most of the lumen of the seminiferous tubules was empty and all generation of germ cells were not present in most of the seminifeous tubules. The interstitium showed a relative increase in volume and interstitial tissue consisted of loose connective tissue, interstitial cells (Leydig cells), few connective cells and blood vessels. This study first time described the microscopic features of testis of Khaki Campbell ducks in Bangladesh during inactive phases of the reproductive cycle.
