Abstract
A study was conducted on the testes from 10 adult dogs. The testes were collected from the healthy dogs from Veterinary Clinical Complex, Namakkal. The testes were reddish- white in colour, oval in shape located within the scrotum. The morphometric values of the left testis were higher than the right testis. The average length, width and thickness of left was 3.73+ 0.07 cm, 2.51+ 0.11cm, 1.77+ 0.04 cm and right testes was 3.47+ 0.13 cm, 2.42+ 0.08 cm, 1.72+ 0.22 cm. The testis of dog was surrounded by connective tissue capsule and consisted of mainly collagen fibers, few elastic fibers, blood vessels and fibroblasts. The seminiferous tubule composed of basement membrane with seminiferous epithelium. The average diameter of seminiferous tubule was 176.659 μm. The greater part of the parenchyma was formed by seminiferous tubules. The capsule, basement membrane of seminiferous tubules, spermatogonia, spermatocytes, Sertoli cells and interstitial cells or Leydig cells were moderately positive for PAS.
