Abstract
This study examine the testis’s histology in males, total of ten adult males (Anas platyrhynchos) were used in this study, the histologicalexamination showed that adult duck testescovers via dense irregular connective tissue referred to as tunica albuginea with mean thickness of (52.12 ± 0.33)micrometer, the seminiferous tubules surrounded by connective tissue fibers, seminiferous tubules mean diameters(127.78 ± 1.55)micrometer, the epithelium lining related to seminiferous tubule have 2 supporting cells types )Sertoli cells( and spermatogenic cell which that is producing the sperms, spermatogenic cells including spermatogonia as well as primary spermatocytes with mean diameter of (9.1 ± 0.21, 13.3 ± 0.30) micrometer, also there is a difficulty in determining secondary spermatocytes because of the remaining short time, since they are quickly converse to spermatids, the diameter of spermatid and spermatids nuclei(7.4± 0.28,4.2 ± 0. 18), micrometer respectively, the mean diameter of Sertoli cells was(10.4 ± 0.23) micrometer. Among the seminiferous tubules, there are a large number of interstitial cells(Leydig cell) the mean diameter,(9.4 ± 0.22(µm,and the Diameter of interstitial cell nuclei (4.5 ± 0.19)micrometer.
