Histochemical Investigations on the Reproductive System in Denizli Cock

In this study, the light microscopic structure of the reproductive system of Denizli cock was investigated by histochemical methods. The lamina epithelialis in the ductuli efferentes contains long ciliated and nonciliated simple cylindrical cells having apically and basally located nuclei, respectively. The ductus epididymidis is made of pseudostratified cylindrical epithelial cells which contain large secretory vacuoles in their apical portions, its lumen contains mature spermatozoa. Spermatogenic germ cells, especially spermatogoniums showed strong staining reactions with basic dye, toluidine blue. Positive staining reactions were observed in spermatogenic germ cells, fibers in interstitial region, basement membrane and around the capillary by phosphotungstic acid-hematoxylene staining. The nuclear structures of spermato-genic germ cells and the internal elastic membrane of arteriole in interstitial region showed positive orcein staining reaction. As a result, histochemical investigations of genital system structure of Denizli cock can be important in terms of the introduction of structural features of the race.
