Very few male mammal Species have internal sex organs, but the Elephant Testicles or testis (plural testes) of elephants are completely inside the body, situated close to the Kidneys and protected against cold temperatures, for example in cold water.

In most placental mammals, including humans, the testes descend into the lower Abdomen or scrotum during development, which is an important evolutionary process that helps keep them cool and achieve optimal function. Elephant testes, however, do not drop, remaining high in the Abdomen. (The mystery of elephant testes)

This is one of the important indications of a previous water-living phase in the evolutions of elephantine animals like Whales and Sirenians (dugong and manatee), but also hedgehog tenrec, cape golden mole, cape elephant shrew, manatee, elephant, and rock hyrax) do not show any testicular descent and have testes positioned at their initial abdominal position near the Kidneys . (Sharma V et al. Loss of RXFP2 and INSL3 genes in Afrotheria shows that testicular descent is the ancestral condition in placental mammals, 2018)

Roger W. Short writes: "The elephant embryo (like the dugong and manatee) has no gubernaculum, no processus vaginalis, no pampiniform plexus, no scrotum, and hence no means of effecting testicular descent".
