What is the condition called that involves inflammation of the testis due to trauma or infection?

Orchitis is the correct term for inflammation of the testis, which can occur due to trauma or various infections, including viral or bacterial sources. This condition typically leads to swelling, pain, and sometimes fever, depending on the underlying cause of the inflammation. It is important to note that while orchitis specifically refers to inflammation of the testis, it can occur in isolation or in conjunction with epididymitis, an inflammation of the epididymis.

Epididymitis primarily affects the epididymis, which is the tube that carries sperm from the testis, and often presents with different symptoms and causes. Testicular torsion involves twisting of the spermatic cord and impairing blood flow to the testis, which is an acute surgical emergency rather than an inflammatory condition. Urethritis refers to inflammation of the urethra, typically caused by infections, and is distinct from issues affecting the testes themselves. Understanding these differences helps clarify the specific nature of orchitis as related solely to the testis.
