They're prone to lash out at their owner with nauseating pain at the slightest offense, get pinched and twisted in tight clothing and develop embarrassing itches and rashes with little provocation. And any testicle owner will likely cringe and involuntarily close his legs at the mention of (thankfully rare) problems such as testicular torsion.

Epididymitis

Epididymitis and orchitis are often lumped together under the term epididymo-orchitis, or sometimes orchi-epididymitis.

But one major difference is that epididymitis affects one particular part of the testicle, the epididymis, while orchitis
