Private Testicular Ultrasound London: Lumps, Pain, Swelling and What Your Scan Can Find

Finding a lump on your testicle, experiencing unexplained scrotal pain, or noticing swelling is frightening. The first thing most men think is testicular cancer — and the anxiety between discovering a change and getting a definitive answer can be overwhelming.

The reality is that the vast majority of scrotal lumps and abnormalities are not cancer. Epididymal cysts, hydroceles, varicoceles, and epididymitis are all far more common causes of scrotal lumps, pain, and swelling. But the only way to know for certain is to look — and ultrasound is the investigation of choice for virtually all scrotal and testicular symptoms.

A private testicular ultrasound at The Wellness London gives you answers the same day. A GMC-registered doctor performs the scan, interprets findings in real time, and tells you whether the finding is benign or needs further investigation — all in a single, discreet, confidential appointment.

What a Testicular Ultrasound Examines

A comprehensive scrotal and testicular ultrasound assesses:

Both testicles. Size, shape, and internal structure (echotexture) are assessed. Each testicle is systematically examined for masses, cysts, calcifications, and any abnormalities. Size comparison between the two testicles is documented — mild asymmetry is normal, but significant differences may indicate pathology.

Epididymis. The epididymis (a coiled tube behind each testicle that stores and transports sperm) is assessed for cysts, inflammation (epididymitis), and enlargement. Epididymal cysts are among the most common scrotal findings and are virtually always benign.

Blood flow (Doppler). Colour Doppler assesses blood flow to each testicle. Increased blood flow can indicate inflammation or infection (epididymo-orchitis). Reduced or absent blood flow is a critical finding that may indicate testicular torsion — a surgical emergency.

Spermatic cord and paratesticular structures. The spermatic cord is assessed for varicocele (dilated veins), lipoma, or other abnormalities.

Scrotal wall and surrounding tissues. Hydrocele (fluid collection around the testicle), scrotal wall thickening, and inguinal hernias extending into the scrotum can all be identified.

Common Findings on Testicular Ultrasound

Epididymal cyst / spermatocele. The most common scrotal finding. A fluid-filled cyst arising from the epididymis. Almost always benign. Usually requires no treatment unless causing significant discomfort due to size.

Hydrocele. A collection of fluid around the testicle, causing painless scrotal swelling. Usually benign. Can be primary (no identifiable cause) or secondary (associated with infection, trauma, or rarely, tumour). Your doctor will assess whether further investigation is needed.

Varicocele. Dilated veins within the spermatic cord, sometimes described as feeling like a "bag of worms." Present in approximately 15% of men. More common on the left side. Usually benign but can be associated with reduced fertility. Ultrasound with Doppler confirms the diagnosis and grades severity.

Epididymitis / epididymo-orchitis. Inflammation or infection of the epididymis (and sometimes the testicle itself). Causes pain, swelling, and warmth. Ultrasound shows an enlarged, hyperaemic (increased blood flow) epididymis. Treatment is typically antibiotics.

Testicular microlithiasis. Multiple tiny calcifications within the testicle. A relatively common incidental finding. While it has been associated with a slightly increased risk of testicular cancer in some studies, the absolute risk remains low. Your doctor will advise on whether any follow-up is recommended based on your individual risk profile.

Testicular cyst. Small cysts within the testicle itself. Usually benign, particularly simple cysts near the tunica albuginea.

Testicular mass. An intratesticular mass (a solid lump inside the testicle) is the finding that requires the most careful evaluation. While not all intratesticular masses are malignant, they are considered suspicious until proven otherwise and typically require urgent referral to a urologist, along with tumour marker blood tests.

Testicular Cancer: What You Need to Know

Testicular cancer is the most common cancer in men aged 15–49 in the UK. Cancer Research UK reports approximately 2,400 cases per year. However, it is important to put this in context:

Testicular cancer is highly treatable. The cure rate exceeds 95% when detected early. This is one of the most treatable cancers in medicine.

Early detection matters. The earlier testicular cancer is diagnosed, the simpler and more effective treatment is. This is why any new testicular lump should be investigated promptly.

Most testicular lumps are not cancer. The vast majority of scrotal lumps are benign — epididymal cysts, hydroceles, and varicoceles are all far more common than testicular cancer.

Ultrasound is the first-line investigation. NICE guidelines and urological guidelines recommend ultrasound as the first investigation for any palpable scrotal abnormality. It can differentiate intratesticular from extratesticular masses, characterise the lesion, and guide the urgency of referral.

If your ultrasound identifies a suspicious intratesticular mass, your doctor at The Wellness will explain the finding honestly, arrange urgent tumour marker blood tests, and facilitate same-day referral to a urologist or the two-week-wait cancer pathway. You will not be left in limbo.

When Should You Get a Testicular Ultrasound?

• You have found a lump on or in your testicle
• You are experiencing testicular or scrotal pain
• One testicle is noticeably larger or swollen
• You have scrotal heaviness or a dragging sensation
• You have noticed changes in the texture of your testicle
• You have a dull ache in the lower abdomen or groin
• You have a suspected or confirmed varicocele (particularly if concerned about fertility)
• You have a history of undescended testicle, which increases testicular cancer risk
• You have a family history of testicular cancer
• You have been diagnosed with infertility and your doctor has recommended scrotal assessment
• You simply want a baseline check for peace of mind

Testicular Scans at The Wellness London: Pricing

All prices include the doctor-performed scan, verbal debrief, and same-day written report.

What to Expect During Your Testicular Ultrasound

No preparation is needed. The scan is performed in a private room with complete confidentiality.

You will lie on your back on an examination bed. A towel is placed across your lap, with only the scrotal area exposed. The doctor applies warm gel and gently moves the ultrasound probe across the scrotum, systematically examining both testicles, the epididymes, and surrounding structures.

The scan takes approximately 15–20 minutes. It is not painful, though you may feel mild discomfort if the area is already tender.

Because a GMC-registered doctor performs your scan, findings are interpreted and explained to you during the appointment. You leave knowing what the finding is, whether it is anything to worry about, and what happens next.

A written report is issued the same day, typically within two hours.

Frequently Asked Questions

Is the scan embarrassing? We understand this concern. The scan is performed professionally, respectfully, and in complete privacy. Only the scrotal area is examined. Many patients tell us the scan was far less uncomfortable than they expected.

Can I bring someone with me? Yes, you are welcome to bring a partner or companion for support. They can wait in the waiting area or be present during the scan — whichever you prefer.

How soon should I get a scan after finding a lump? As soon as possible. While most lumps are benign, prompt investigation provides reassurance and ensures that the small number of significant findings are caught early.

Will my GP be informed? Only with your consent. You receive your report directly. If you would like a copy sent to your GP, we arrange this promptly.
