Abstract:
The seasonal testicular morphology and the morphometry of the interstitial tissue were studied in 62 camels at Algerian extreme arid region. The maximal testicular size was recorded during the rutting season. In this period, the interstitial tissue occupied high area and volume with significant increase of the intertubular constituent’s volume, hypertrophy of the Leydig cell, and maximal number of Leydig cells per testes. Therefore, the highest ratios of seminiferous tubules to interstitial tissue area and volume and the highest fraction of intertubular empty space were recorded during the non-rutting. The greater Leydig cell nucleus size was observed during the post-rutting season. Finally, the numerical density of Leydig cells did not significantly change over the year. These results provide information on the relationship between seasonal changes of camel testicular morphology and the histomorphometry of the testicular endocrine compartment in camels at the arid livestock conditions of the southeastern Algerian desert.
