In addition, they produce a hormone that is more often. Specifically, Steph Yin of the Times reports on a German team that studied the DNA of 71 mammals (by which I think he means 71 species) and found that testicular descent is an ancestral trait that was lost in elephants and certain other mammals.

That is, elephants store their testicles internally, whereas most other mammals store theirs externally. Wensing CJ, Testicular descent in some domestic mammals 2. The nature of the gubernacular change during the process of testicular descent in the pig.

How Do Undescended Testicles Happen. As a baby boy grows inside his mother's womb, his testicles form inside his abdomen and move down (descend) into the scrotum shortly before birth.

But in some cases, that move doesn't happen, and the baby is born with one or both testicles undescended. The majority of cases are in male babies born prematurely. Testis Descent. Testicular descent is a two-stage process that starts at about 8 weeks' gestation and is usually complete by the middle of the third trimester.
