This brings us to the intriguing topic of testicle temperature. In mammals, the production of healthy sperm relies on the testes being several degrees cooler than the body temperature. Consequently, the descent of testicles into a scrotum plays a vital role in cooling them as maturity approaches. Elephants, however, lack the genes responsible for this descent, resulting in their testicles remaining inside their bodies even in mature bulls, subjecting them to elevated temperatures.
Considering elephants’ inherent vulnerability to climatic challenges due to their bulk, unfavorable surface ratio, thick skin, and heat exchange mechanisms centered on blood flow in the ear flaps, their body temperatures can soar to levels that are detrimental to mammalian metabolism and detrimental to healthy sperm production.
Hot testicles may hold the secret to elephants’ anti-cancer genes
This one caught be off guard. I had vaguely wondered about why I never saw them exposed in pictures. Now I know.
