If you have testicular or scrotal pain, the doctor or other health care professional's first goal is to determine whether or not the pain is caused by testicular torsion, because this is a surgical emergency requiring prompt medical attention. Though the following information may be used to help differentiate the symptoms of testicular torsion and epididymitis, any male with testicular pain should not delay and see a doctor or other health care professional right away because trying to distinguishing between the two conditions often can be difficult.
2) Irreversible adaptation to sperm competition . It has been suggested that the ancestor of the boreoeutherian mammals was a small mammal that required very large testes (perhaps rather like those of a hamster ) for sperm competition and thus had to place its testes outside the body.  This led to enzymes involved in spermatogenesis, spermatogenic DNA polymerase beta and recombinase activities evolving a unique temperature optimum, slightly less than core body temperature. When the boreoeutherian mammals then diversified into forms that were larger and/or did not require intense sperm competition they still produced enzymes that operated best at cooler temperatures and had to keep their testes outside the body. This position is made less parsimonious by the fact that the kangaroo , a non-boreoeutherian mammal, has external testicles. The ancestors of kangaroos might, separately from boreotherian mammals, have also been subject to heavy sperm competition and thus developed external testes, however, kangaroo external testes are suggestive of a possible adaptive function for external testes in large animals.
