Some morphometric and histological description of the seminiferous, striaghted and rete testis tubules in the testis of indogenous male goats (two years old)‎

Abstract EN

The present Study was carried out on (15) testis indogenous male goats(two years)old .

The testes was surrounded by capsule mean thickness (230 ± 3.5) micrometer.

The internal structures of the testes represented by seminiferous tubules mean diameters (258 ± 1.9) micrometer.

The wall of seminiferous tubules consist of spermatogenic cells and supporting cells (Sertoli cells).

The spermatogenic cells included spermatogonia and primary spermatocytes (mean diameters 10.5 ± 1.7, 16.3 ± 2.3) micrometer respectively.

Difficult to determine the secondary spermatocytes,due to remain for short time, because they converse quickly to spermatids ,therefore ; diameters of secondary spermatocytes were thought approximately equal the diameters of spermatids and Spermatids (mean diameter 9.52 ± 1.49) micrometer.

The mean diameter of supporting cells was (13.

58 ± 2.11) micrometer.

Among the seminiferous tubules there are interstitial tissue was occupied by interstitial cells (Leydig´s cells) the mean diameter (12.32 ± 3.85) micrometer.

The seminiferous tubules were opened into striaghted tubules which lined by epithelium was graduated from stratified cuboidal endothelium to simple cuboidal endothelium when striaghted tubules connected with rete testis tubules .The mean diameters of striaghted tubules were ( 156.3 ± 2.36) micrometer.

The rete testis were lined by simple squamous endothelium (the mean diameter 74 ± 1.48) micrometer.
