What to expect if I have Epididymoorchitis  (Outlook/Prognosis)?
Getting the right diagnosis and treatment for epididymoorchitis caused by bacteria can usually preserve the normal testicle function.
If the testicle does not completely return to normal after treatment, further testing to rule out testicular cancer should be done. If not treated, or in some other cases, the condition can become long-term (chronic). In chronic cases, there is usually no swelling, but there is pain.
Mumps orchitis cannot be treated, and the outcome can vary. Men who have had mumps orchitis can become sterile. </s>
