Varicocele Embolization
Varicocele embolization is a safe, image-guided, non-surgical procedure that treats varicocele—an abnormal enlargement of the veins within the scrotum, similar to varicose veins in the legs. It can cause pain, testicular swelling, and male infertility.
During the procedure, an interventional radiologist inserts a catheter through a vein in the groin or neck and deploys small coils or a special blocking agent to stop blood flow through the faulty vein. This relieves pressure, improves sperm quality, and restores normal venous circulation.
When is embolization performed?
Varicocele embolization is typically recommended when a varicocele causes symptoms or is linked to infertility. While many varicoceles are asymptomatic, they can sometimes lead to dull or aching scrotal pain, swelling, or testicular atrophy—particularly in adolescents, where they may impair testicular growth. In adult men, varicoceles are a common, treatable cause of decreased sperm quality and fertility challenges.
Treatment is usually advised in the following situations:
- Persistent scrotal pain or heaviness
- Visible or palpable varicocele
- Abnormal semen analysis associated with infertility
- Discrepancy in testicular size (especially in adolescents)
- Personal preference for a minimally invasive approach
Both surgical repair and embolization are effective treatment options. However, embolization is less invasive, does not require general anesthesia, and allows for faster recovery—typically performed as a same-day outpatient procedure using only a small needle puncture.
Understanding Varicocele Embolization
Who Is a Candidate for Embolization?
You may be a candidate for varicocele embolization if:
- You have been diagnosed with a varicocele via physical exam or ultrasound.
You experience symptoms such as:
- Dull or sharp pain in the testicle
- Scrotal swelling or heaviness
- Visible enlarged veins
- Infertility or abnormal semen analysis
- You are looking for a non-surgical treatment option.
Preparing for Varicocele Embolization
Your doctor will guide you through the steps needed to prepare for the procedure. Be sure to:
- Share your complete medical history and medications, including supplements.
- Inform your doctor about allergies, especially to contrast dye or anesthesia.
- Stop taking blood thinners or NSAIDs if advised.
- Avoid eating or drinking for 4–8 hours before the procedure if sedation is planned.
- Arrange for someone to accompany you home afterward.
You may need a scrotal ultrasound and/or semen analysis as part of your pre-procedure assessment.
What Happens During the Procedure?
- You’ll lie on an X-ray table and be given a sedative through an IV to help you relax.
- The interventional radiologist will numb a small area in your groin or neck.
- A thin catheter is inserted into a vein and guided to the varicocele using X-ray imaging.
- A contrast dye may be injected to help visualize the vein structure.
- The doctor releases tiny metal coils or a sclerosing agent to block the enlarged vein.
- Blood flow is rerouted through healthier veins, relieving pressure and inflammation.
- The catheter is removed and a small bandage is applied. No stitches needed.
- The entire procedure typically takes about 1 hour.
After the Procedure
- You'll be monitored briefly and can usually return home the same day.
- Most patients resume normal, non-strenuous activities within 24–48 hours.
- You may experience mild discomfort or scrotal tenderness for up to a week.
- Avoid heavy exercise and sexual activity for 7–10 days.
- A follow-up visit will confirm healing and symptom improvement.
- If you have fertility concerns, a repeat semen analysis may be recommended after 3–6 months.
Why Varicocele Embolization may be the best choice
- Minimally Invasive – No surgical incisions or stitches
- Outpatient Procedure – Go home the same day
- Fast Recovery – Resume daily activities in 24–48 hours
- High Success Rate – Comparable to surgery, with fewer complications

Frequently Asked Questions (FAQ)
What does the equipment look like?
A catheter (thin, flexible plastic tube) about 1/8 inch wide is used to reach the varicocele. X-ray machines, contrast dye, and ultrasound equipment guide the procedure.
How long is the hospital stay?
Most patients go home the same day. Hospital admission is rare.
What are the potential risks of varicocele embolization?
Varicocele embolization is considered very safe. Potential, but rare, risks include:
- Mild scrotal pain or inflammation
- Allergic reaction to contrast dye
- Infection or bleeding at catheter site
- Migration of coils (rare)
- Failure of procedure or recurrence of varicocele
Discuss your individual risks with your interventional radiologist at RIVEA before the procedure.
Is it painful?
You may feel minor discomfort at the injection site or a warm sensation during contrast dye injection. Most patients report minimal pain and fast recovery.
When can I return to normal activities?
Light activity is possible within 24 hours. Avoid vigorous exercise and sex for about 7–10 days.
Will it improve fertility?
Many patients experience improved sperm count and motility after the procedure. A semen analysis may be done 3–6 months post-treatment.
Can the varicocele return?
Recurrence is uncommon but possible. If needed, repeat embolization or surgery can be considered.
What are the risks?
Rare risks include infection, allergic reaction, or coil migration. Overall, varicocele embolization is very safe and well-tolerated.
How successful is varicocele embolization?
Studies show success rates of 85–95%, comparable to surgical options, with faster recovery and fewer complications.
