ABSTRACT
The morphometric measurements of the testicles is intended to measure the dimensions of constituenttestis parenchyma quantitatively evaluating spermatogenesis. This study aimed to analyze the spermatogenesisof sheep Santa Ines and crossbred Santa Ines and Dorper watching the racial crossing alter testis function. Weused eight sheep, four Santa Ines and four crossbreed of Santa Ines/Dorper. After castration the animals gavethe Gonadosomatic index. Gauged to volume ratio of testis compartments using a reticle. The constituents of thetubular casing were evaluated Lamina propria, seminiferous epithelium of the lumen and interstitialcompartment constituents Leydig cells, blood vessels and connective tissue. Only the tubular diameter andheight of the seminiferous epithelium showed significant differences, being higher for sheep Santa Ines. It wasconcluded that there was little difference in testicular morphometry of animals studied and it was found that theracial cross does not induce significant changes in parameters between groups.
