Is isolated orchitis uncommon in adults and usually associated with epididymitis?

Explanation:
Isolated orchitis in adults is uncommon because most scrotal infections start in the epididymis and spread to the testis, causing epididymo-orchitis rather than a pure testicular infection. The epididymis is more often the initial site of infection from ascending organisms or prostatitis, and its close anatomical and vascular connections to the testis allow spread to the testis. Viral causes like mumps can affect the testis, but for bacterial infections in adults, isolated testicular involvement without epididymal involvement is rare. So the statement is true.
