Orchitis is inflammation or infection of one or both of your testicles.

What causes orchitis?

The cause of orchitis may be unknown. It may be caused by any of the following:

  • Infections caused by the mumps virus , or other bacteria
  • Trauma or injury of the testes
  • Sexually transmitted infections such as Chlamydia or gonorrhea

What are the signs and symptoms of orchitis?

  • Pain in one or both testicles
  • Swelling of one or both testicles
  • Fever
  • Tenderness in your groin, lower abdomen, or scrotum
  • Nausea and vomiting

How is orchitis diagnosed?

Your healthcare provider will ask about your symptoms and about any health conditions you have. He may also examine your testicles, prostate, and groin. You may also need any of the following tests:

  • Urine tests may be done to check for an infection
  • A sample of discharge may be done to check for a sexually transmitted infection.
  • An ultrasound uses sound waves to show pictures of your testicles on a monitor. An ultrasound may show an abscess (collection of pus).

How is orchitis treated?

Treatment for orchitis depends on the cause of your orchitis. You may need any of the following:

  • Medicine can help decrease pain or swelling. You may also need medicine to treat a bacterial infection.
  • NSAIDs , such as ibuprofen, help decrease swelling, pain, and fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask if NSAIDs are safe for you. Always read the medicine label and follow directions. Do not give these medicines to children under 6 months of age without direction from your child's healthcare provider.
  • Apply ice on your testicles for 15 to 20 minutes every hour or as directed. Use an ice pack, or put crushed ice in a plastic bag. Cover it with a towel. Ice helps prevent tissue damage and decreases swelling and pain.
  • Rest in bed as directed. Lying down will help to keep your scrotum elevated.
  • Scrotal support may be recommended. An athletic supporter provides scrotal support and may make you more comfortable when you stand. Ask your healthcare provider how to use an athletic supporter.
