Arterial blood flow is the main source of testicular heat in bulls and higher ambient temperatures significantly increase testicular blood flow

Two experiments were done in bulls to determine: total testicular blood flow, testis oxygenation and heat, and effects of ambient temperature on testicular temperatures and blood flow. In Experiment 1, arterial blood flow to testes and testicular oxygenation and heat were determined in Angus bulls (n = 8). Blood temperature and hemoglobin O2 saturation were both greater (P
