A scrotal ultrasound (also called a testicular ultrasound) is a safe, painless, and non-invasive imaging test used to examine the scrotum — the sac that holds the testicles. It plays an important role in evaluating symptoms like pain, swelling, or lumps in the testicles or surrounding tissue.
If your doctor has recommended a scrotal ultrasound, here’s what you need to know.
What Is a Scrotal Ultrasound?
A scrotal ultrasound uses high-frequency sound waves to create real-time images of the testicles, epididymis (a small tube at the back of each testicle that stores and carries sperm), and the surrounding tissues.
This test is typically performed by a trained sonographer or radiologist and usually takes around 15–30 minutes.
What Is a Scrotal Ultrasound Used For?
Scrotal ultrasounds are commonly used to investigate a variety of issues affecting the testicles and scrotal area.
Evaluating Pain or Swelling
It can help identify:
- Epididymitis (inflammation of the epididymis)
- Orchitis (inflammation of the testicle)
- Testicular torsion (a medical emergency where the spermatic cord twists and cuts off blood supply)

Checking for Lumps or Masses
If a lump is felt during a physical exam, the ultrasound helps determine:
- Whether the lump is solid or fluid-filled
- If it is likely benign (e.g., cyst or hydrocele) or possibly cancerous (e.g., testicular tumor)

Diagnosing Testicular Cancer
Ultrasound is the first-line imaging test used to assess for signs of testicular tumors, especially in younger men.
Assessing Trauma
If you’ve experienced an injury to the scrotum, ultrasound can check for:
- Rupture of the testicle
- Internal bleeding (hematocele)
- Other soft tissue damage
Investigating Fertility Issues
It may help evaluate causes of male infertility, including:
- Varicocele (enlarged veins in the scrotum)
- Blockages or abnormalities in the spermatic cord
Guiding Other Procedures
In some cases, scrotal ultrasound can be used to guide needle aspiration or other minor procedures involving the scrotal sac.
What to Expect During the Test
- You’ll be asked to lie on your back.
- A towel or support will gently lift the scrotum to hold it in place.
- A warm gel is applied to the skin to help transmit sound waves.
- The ultrasound probe (transducer) is moved over the scrotal area to take images.
💡 Tip: The procedure is not painful, but you may feel slight pressure. It’s non-invasive and there’s no recovery time needed—you can return to normal activities right away.
Is It Safe?
Yes. Scrotal ultrasound is extremely safe—it uses sound waves, not radiation, and there are no known risks or side effects.
When Should You Get a Scrotal Ultrasound?
You may be referred for a scrotal ultrasound if you experience:
- A lump in your testicle or scrotum
- Swelling or pain in the testicular area
- Changes in testicle size or firmness
- Sudden pain (which could signal torsion)
- Signs of infection or trauma
- Infertility investigations

Final Thoughts
A scrotal ultrasound is a quick, safe, and effective way to evaluate testicular health. Whether it’s for investigating a lump, managing pain, or checking fertility concerns, this test provides valuable information that helps guide treatment.
Don’t ignore changes in your testicles—early evaluation can lead to faster treatment and better outcomes.
