Scrotal/testicular thermoregulation is a complex process controlled by numerous local mechanisms that attempt to maintain the testes at conditions ideal for spermatogenesis. This article provides a background of the anatomy and physiology of the bovine scrotum and its contents with emphasis on thermoregulation. Experiments are cited that demonstrate scrotal/testicular thermoregulation mechanisms and the effect that changes in ambient temperature have on internal testicular temperature and subsequent seminal quality.
