Anatomical and histological study of male reproductive system in guinea fowl: Testis, Epididymis, Ductus deferens

Guinea fowls are considered of pheasant birds. Since anatomical and histological differences were reported in the male reproductive system, and there is no anatomical and histological research performed on reproductive system of guinea fowl, this study was performed on the male reproductive system of guinea fowl in Sexual and non-sexual period. For this research 10 male guinea fowl were selected and reproductive system were anatomically studied. Then tissue samples were taken, and stained by Haematoxylin and Eosin. Anatomical and histological results were similar to other birds. Anatomical results showed the left testis was larger than the right testis, and in the sexual period it was almost twice than the non-sexual period. Epididymis was an elliptical disk shape and there was no head, body, and tail. Epididymis there was in the mediodorsal of the testis. Ductus deferens was also seen as a zigzag duct. In the histological study, there was no Mediastinum testis. Straight tubules was after seminiferous tubules and connected to rete testis, and this epithelium was Simple cuboidal epithelium or squamous epithelium. Sertoli cells with a big nucleus and euchoromatin extending to the epithelium depth, and leydig cells was spherical shape and there was in between seminiferous tubules. Epithelium of ductus deferens was similar to epididymis, but there was no epithelial gland in it.
