Effects of Temperature on the Biochemistry of the Testis

  • Anna Steinberger
Part of the Advances in Experimental Medicine and Biology book series (AEMB, volume 286)


In most mammalian species, including human, the male gonads are located outside the body cavity in a highly specialized skin pouch — the scrotum. Generally, the scrotal and testicular temperatures are below the core body temperature, although the differences between abdominal and testicular temperatures vary among species 8.3 -8.5°C in the rat and mouse to approximately 2°C in the rhesus monkey (Harrison and Weiner, 1948). The lower temperature is of great importance for the maintenance of normal testicular functions, particularly the process of spermatogenesis. Clearly, the existing mechanisms for controlling testicular temperature must have developed through evolutionary processes to assure the survival of the species; however, the reason as to why nature chose this particular form of adaptation is not clear.
