Régulation thermique du testicule

Resume

Il apparaît qu'une nécessité a évolué chez de nombreux mammifères pour que les testicules soient maintenus à une température plus basse que celle des organes abdominaux. Un certain nombre de structures anatomiques spécialisées sont impliquées dans ce processus, et il est évident que le testicule est sensible à l'élévation de température.

Abstract

It appears that a need has evolved in many mammals for the testes to be kept at a temperature less than that found in other abdominal organs. A number of specialized anatomical structures are involved in this process, and it is clear that many aspects of sperm production and function can be adversely affected if the testes of the whole animal are exposed to temperatures only slightly above their normal values.
