Studies on endocrinological interrelations in Fighting Bulls are rare, and all the mechanisms that contribute to their aggressiveness are not well understood. How Testosterone deficiency adjusts exactly the metabolism of Cholesterol and Vasopressin remains misunderstood. A total of 10 Fighting Bulls Breed were studied. Blood samples were collected and analyzed immediately after slaughter to determine the levels of Testosterone, Cholesterol and Vasopressin (ADH). There is a combination of low levels of cholesterol, high levels of testosterone and ADH, coinciding with a greater aggressiveness. The correlation of ADH vs testosterone is positive and significant at a level of 5%. The averages found for total cholesterol, serum testosterone and ADH are respectively - 139.4 mg / dL, 14.14 ng / dL and 440.7 pg / ml. And, there is an evident and putative correlation between Serum Testosterone above 10.4 ng / dL and the Behavior of the fighting bulls, qualified with greater aggressiveness.
