Embolization of varicocele in Turkey: what it is and how it works
Embolization of varicocele is a keyhole-sized, image-guided procedure in which an interventional radiologist closes the enlarged vein that is causing a varicocele. A thin catheter is passed through a vein in the groin, neck or arm, guided by X-ray, into the testicular (gonadal) vein. Tiny metal coils, a sclerosing agent or a medical glue are then released to block the vein, so blood stops pooling around the testicle and is rerouted through healthy veins. There is no cut in the scrotum and no general anaesthetic. Hospitals in Turkey with an interventional radiology unit offer it as a day-case procedure.
This guide explains how embolization of varicocele works, what the evidence says, what it costs compared with the UK, US and Germany, how recovery goes, what can go wrong and how to check a hospital. If you are weighing the surgical route, see our guide to varicocelectomy, and for the wider range of men's health options see our urology treatments in Turkey.
What is a varicocele and when does it need treatment?
A varicocele is a collection of dilated veins in the scrotum, similar to varicose veins in the leg. It is usually found on the left side because of the way the left testicular vein drains. Many men have one without knowing and never need treatment. Treatment is considered when a varicocele causes a persistent dragging ache, when the affected testicle is smaller than the other, or when a couple has been trying for a baby, the semen analysis is abnormal and no other cause has been found. A varicocele that causes no symptoms and has no effect on semen is normally just monitored. Your urologist will confirm the diagnosis with an examination and a scrotal Doppler ultrasound, which also grades its size.
How is embolization of varicocele done, step by step?
The procedure usually takes 30 to 60 minutes. You lie on an X-ray table and the skin at the puncture site, most often in the groin or at the right side of the neck, is numbed with local anaesthetic; mild sedation can be added if you are anxious. A needle and then a thin catheter are advanced into the testicular vein. The radiologist injects contrast dye to show the vein and any side branches, then deploys coils or a sclerosant to seal the vein along its length. A final X-ray confirms the flow has stopped. The catheter is removed, pressure is held on the puncture and a small dressing is applied. You rest for a few hours and normally go back to your hotel the same day.
The radiologist can treat both sides in the same session if needed, which is useful when a smaller right-sided varicocele is present.
Does embolization of varicocele work? What the evidence says
For pain and for the technical aim of closing the vein, the evidence is reasonably good: a large majority of men with a painful varicocele report improvement after treatment, whether by embolization or surgery. For fertility the picture is more careful. Guidance from the European Association of Urology supports treating a clinically palpable varicocele in men from couples with unexplained infertility and abnormal semen, because semen quality often improves, but it does not recommend treating men whose semen is normal in the hope of preventing future problems. Better semen results do not always translate into a pregnancy, which also depends on your partner's age and fertility.
Recurrence is the main limitation. Embolization can fail to close every small collateral vein, and a minority of men need a repeat procedure. A trustworthy hospital will discuss this openly and will not promise a pregnancy or a permanent cure.
Embolization of varicocele cost in Turkey compared with the UK, US and Germany
The figures below are approximate ranges for one procedure, not hospital quotes. The final price depends on the number of sides treated, the embolic material (coils cost more than a sclerosant), the type of sedation, the scans before and after, and whether you stay overnight. Each hospital confirms its own price in a written quote.
| Country | Approximate cost range |
|---|---|
| Turkey | €1,200 – €3,500 |
| United Kingdom | €3,000 – €7,000 |
| United States | €5,000 – €13,000 |
| Germany | €2,500 – €6,500 |
A package normally includes the consultation, Doppler ultrasound, the procedure and the radiologist's fee, the embolic material, a short stay and airport transfers. Ask whether a repeat semen test or follow-up scan is included, and whether a second procedure would be charged if the varicocele recurs.
Embolization or surgery: which suits a varicocele better?
There are three established ways to treat a varicocele: radiological embolization, microsurgical varicocelectomy through a small cut in the groin or below it, and laparoscopic ligation. Each has a place, and the choice depends on your anatomy, whether the varicocele has come back after surgery, and what the hospital offers.
| Method | Suited to | Typical limits |
|---|---|---|
| Embolization | Men who want no scrotal or groin incision, a quick return to work, or treatment of a recurrence | Needs X-ray exposure and contrast; vein may not be reachable in some men |
| Microsurgical varicocelectomy | Fertility-focused patients; usually the lowest recurrence rates in studies | Small incision, general or spinal anaesthesia, needs a skilled microsurgeon |
| Laparoscopic ligation | Selected cases, sometimes when other abdominal surgery is planned | General anaesthesia; higher hydrocele risk than microsurgery |
Neither route is right for everyone. If your main aim is a baby, ask the urologist to explain why they recommend one method over another, and whether treating the varicocele is advisable before starting IVF treatment.
Who is a good candidate, and who is not?
Good candidates are adult or adolescent men with a confirmed varicocele who have a persistent ache, testicular shrinkage or abnormal semen. You are less suited if the varicocele causes no problems and your semen is normal, if you are allergic to iodine contrast dye, if you have kidney disease that limits contrast use, or if the scan shows a vein anatomy that cannot be catheterised safely. A very small, symptom-free varicocele is usually better watched. Men who have already frozen sperm are sometimes advised on timing; see our guide to sperm cryopreservation.
Embolization of varicocele recovery: what to expect in the first weeks
Most men walk out the same day. Expect a bruise and tenderness at the puncture site and a mild ache in the groin or scrotum for a few days; ordinary painkillers usually suffice. Some men feel a short-lived back or flank pain right after the vein is closed. Light activity is fine the next day, but avoid heavy lifting, sport and sexual activity for about a week, or as the radiologist advises. Desk work often resumes after two to three days. Most people need only two to three nights in Turkey, enough for the procedure and a check the next day, then fly home as long as the puncture site is healing well.
Embolization of varicocele results: when do you see a change?
Pain often eases within days to weeks. A semen analysis is repeated about three months after treatment, because sperm take roughly 70 to 80 days to develop, and again at six months; improvement in concentration and movement, when it happens, builds slowly. Testicular size can partly recover in teenagers. A follow-up Doppler scan checks that the vein has closed. Be wary of any clinic that publishes only semen results from selected patients; ask what share of its patients saw improvement and how many needed a second procedure.
Risks and complications of embolization
Every procedure carries risks. Common effects are bruising and soreness at the puncture site and a brief ache in the scrotum. Less common problems include a reaction to contrast dye, infection or a haematoma at the entry point, inflammation of the vein (phlebitis), and movement of a coil away from the target, which a radiologist can usually retrieve. Hydrocele, a fluid collection around the testicle, is less frequent than after open surgery. Rarely, the vein cannot be reached and the procedure is stopped. X-ray exposure is low but real, which matters for younger patients. Recurrence of the varicocele can happen. Reliable information on interventional radiology is published by the British Society of Interventional Radiology and the Society of Interventional Radiology (SIR); the European Association of Urology publishes guidance on male infertility.
How to choose a hospital and radiologist, and questions to ask
Check that the procedure is done by an interventional radiologist or an experienced urologist-radiologist team in a licensed hospital with modern angiography equipment, that your history of allergies is recorded, and that you receive a written plan and price before paying a deposit. Red flags include promises of guaranteed fertility, quotes with no breakdown, pressure to book quickly and no plan for follow-up. Read how our process works and request a plan through our free quote page. Useful questions:
- Which embolic material will be used, and why?
- Will both sides be checked in one session?
- How many varicocele embolizations does the radiologist perform each year?
- What happens if the varicocele recurs, and is a repeat covered?
- Who reviews my semen tests after I return home?

Frequently asked questions
It is a catheter procedure in which a radiologist blocks the enlarged testicular vein with coils or a sclerosing agent, so blood stops pooling in the scrotum. It uses a needle puncture in the groin, neck or arm rather than a cut in the scrotum.
Many men with a painful varicocele report less pain, and semen quality often improves when the varicocele is treated in men with abnormal results. It does not guarantee a pregnancy, and the varicocele can come back in some men.
Approximate ranges are €1,200 to €3,500 in Turkey, against roughly €3,000 to €7,000 in the UK. The price depends on one or both sides, the embolic material and sedation; a hospital confirms its price in a written quote.
The skin is numbed, so you feel pressure rather than sharp pain. Afterwards expect a bruise and a mild ache for a few days. Most men return to desk work in two to three days and avoid heavy exercise for about a week.
Embolization avoids a surgical incision and has a quick recovery, while microsurgical varicocelectomy usually has lower recurrence in studies. The right choice depends on your anatomy, goals and the team's experience.
Yes. Small collateral veins can keep refilling, and a minority of men need a second procedure. Ask the hospital how it handles recurrence and whether a repeat is included in the quoted price.
A semen analysis is usually repeated at three and six months, because sperm take about 70 to 80 days to develop. Improvement, if it comes, appears gradually and varies between men.
It is a well-established procedure with low complication rates. Possible problems include bruising, a contrast dye reaction, infection, coil movement and X-ray exposure. A licensed hospital with an experienced radiologist reduces the risks.
Usually yes, once the radiologist has checked the puncture site, often the day after the procedure. Avoid lifting luggage for a few days and keep the site clean and dry.
Two to three nights is usual: one for the procedure and a check the next day. Allow an extra day or two if you want a follow-up ultrasound before flying.
