What is the term for inflammation of the testes caused by trauma or infection?

The correct term for inflammation of the testes caused by trauma or infection is orchitis. This condition specifically refers to the swelling and irritation of the testicles, which can result from a variety of factors, including viral or bacterial infections, as well as physical trauma. Orchitis can lead to pain, swelling, and potential complications if not treated, emphasizing the importance of recognizing and diagnosing this condition promptly.

In contrast, epididymitis refers to inflammation of the epididymis, a structure located at the back of each testis responsible for storing and maturing sperm. While related, it is a distinct condition. Testitis is less widely used and can refer to inflammatory conditions of the testis, but it is not the standard term recognized in medical literature. Nephritis pertains to inflammation of the kidneys, which is unrelated to the testes. Therefore, orchitis is clearly the most accurate term for the specific inflammation of the testes in this context.
