Abstract
The present work were aimed to study the histology of testis in male of quail (C.C. japonica). Ten adult male of quails, nine weeks old, were used in this study. Experimental birds were anesthetaized by using chloroform inhalation in closed champers and then the necropsed technique were applied to remove the testis and study their histological characteristics. The histological examination were showed that the male of Quail birds has a compound tubular testis. It covers by dense irregular connective tissue which called Tunica albuginea. The testis did not clearly divided into lobes because there is thin interstitial connective tissue septa between the adjacent seminiferous tubules. The convoluted seminiferous tubules surrounded by thin sheath consist of connective tissue fibers, myoid cells and smooth muscle fibers. Epithelium lining of semniferous tubules have two types of cells: supporting cells (Sertoli) and spermatogonium cells which produce the sperms. The extension of these tubules toward the epidydimus became like striated tubules (tubuli recti) less in diameter and lined by sertoli cells only. The striated tubules were anastomosing with each other to form rete testis which is directly contact with efferent ducts. The histological study also showed that the testis of quail has no mediastinum testis.
