Histomorphological Studies on the Spermatogenic Cells, Sertoli Cells and the Interstitial Tissue of the Testis in Adult Bakerwali Goat

Abstract

The present histological study was conducted on the testis of adult Bakerwali goats. The seminiferous tubules
were comprised of type A and B spermatogonia, primary spermatocytes at various phases of differentiation
(leptotene, zygotene, pachytene and diplotene), secondary spermatocytes, round spermatids, elongated
spermatids and spermatozoa. Sertoli cells were irregularly columnar cells that extended from the basal lamina to
the lumen of tubules. The interstitial tissue lay between the seminiferous tubules and consisted of loose
connective tissue network, blood and lymph vessels, fibrocytes, fibroblasts and interstitial or Leydig cells.
The Leydig cells had spherical shaped vesicular nucleus. The cytoplasm was eosinophilic and vacuolated.
