Scrotal/testicular thermoregulation is a complex process controlled by
numerous local mechanisms that attempt to maintain the testes at cond
itions ideal for spermatogenesis. This article provides a background o
f the anatomy and physiology of the bovine scrotum and its contents wi
th emphasis on thermoregulation. Experiments are cited that demonstrat
e scrotal/testicular thermoregulation mechanisms and the effect that c
hanges in ambient temperature have on internal testicular temperature
and subsequent seminal quality.
