چکیده
Testes have several primary functions such as male gametes production (spermatozoa) and secretion of several endocrine factors as follow; 1) steroid and 2) protein hormones production which are facilitating elements in healthy reproductive function of mammals. The potential of animal functional endocrine reservoir could be an interesting founding in the animal reproduction management.  Therefore, the current study aimed to analyze the functional endocrine reserves of testes in 12- and 18-month-old boars of different breeds. Four different boars breed, Large White, Landrace, Duroc, and Tempo, were considered as the animal model in this research (n=10). To determine the functional endocrine reserves of the testes at 12 and 18 months of age, boars received injections of  human chorionic gonadotropin (hCG) 3 times every 72 hours. To measure testosterone, blood samples were (10 mL) taken from jugular vein before the administration of hCG, as well as 2, 12, 24, 48, and 72 hours after administration of each of three hCG injection. The index of endocrine activity of the testes was determined by the formula: Ita = Т1 –Т0 / Т0  where Ita is the index of endocrine activity of the testes, T0 is the concentration of testosterone before the administration of hCG, and T1 is the maximum testosterone concentration after the third administration of hCG. The effect of the hCG injection on the testes of the boars at different age periods indicate that the testes of Large White and Duroc boars have higher potential endocrine reserves in relation to the Landrace and Tempo breeds.
