Embolization or surgery?
When a varicocele aches or affects fertility: coils or an operation, side by side.
OVERVIEW
A varicocele is treated only for particular reasons: persistent aching or heaviness, subfertility alongside abnormal semen findings, arrested testicular growth in an adolescent, or a varicocele that has returned after an operation. Where one of those applies, the faulty spermatic vein can be closed two ways — surgical ligation through a cut in the groin, or embolization. Dr Marios Agathangelou performs varicocele embolization in Nicosia and Limassol, Cyprus — covered by GESY, €0 for GESY beneficiaries. Embolization reaches the vein from inside through a 1–2 mm puncture at the neck or groin and seals it with coils, under local anaesthetic and light sedation, with no surgical incision in the scrotum; surgery ties the veins off through an incision, usually under a general or spinal anaesthetic. Embolization brings fewer complications, hydrocele above all; surgery comes back slightly less often.
Below are the three paths side by side, starting with the one most men need: no treatment at all.
THE THREE OPTIONS
LEAVING IT ALONE
SURGICAL LIGATION
EMBOLIZATION
SIDE BY SIDE
| EMBOLIZATION | SURGERY (LIGATION) | |
|---|---|---|
| What is done | The vein is sealed from inside with coils | The veins are tied off through a cut in the groin |
| Anaesthetic | Local, with light sedation | Usually general or spinal |
| Cuts | A 1–2 mm puncture at the neck or groin; no surgical incision in the scrotum | An incision in the groin |
| Hydrocele (fluid around the testicle) | Clearly less common | The commonest complication of the operation |
| Back to routine | One to two days | About one to two weeks |
| Semen findings | Often improve; not a promise of a pregnancy | Often improve; the same caution applies |
| If it comes back | Slightly more often than after surgery; the embolization can be repeated | Slightly less often; least of all after microsurgical repair |
| GESY | Covered: €0 for the procedure | Covered |
WHO EACH SUITS
Embolization tends to suit you if the varicocele aches or drags, if you would rather avoid a general anaesthetic and an incision, if a previous operation has not held, or if hydrocele is the complication you least want to risk.
Surgery tends to suit you if the vein cannot be reached with a catheter — it happens, and the procedure is stopped rather than forced — or if your urologist recommends microsurgical repair for the smallest chance of it returning.
Before either, the real question is whether this varicocele needs treating at all. Many do not, and I would rather tell you that than treat you. Where fertility is the reason, the decision belongs with a urologist or a fertility specialist as much as with me.
GESY COVER
GESY covers both. Embolization is done as an inpatient admission and the admission includes the treatment, so the procedure itself costs you nothing. Neither route is the cheaper one.
The first outpatient visit — the ultrasound, and the conversation about whether to treat at all — may carry a small co-payment, as any specialist visit does. Both routes need a valid referral.
COMMON QUESTIONS
Dr Marios Agathangelou, an interventional radiologist, sees patients in Nicosia and Limassol and performs varicocele embolization. It is covered by GESY — €0 for GESY beneficiaries.
Often not. Treatment is for persistent pain or heaviness, subfertility with abnormal semen findings, arrested testicular growth in an adolescent, or a varicocele that has returned after an operation. One found by chance that causes nothing is watched.
Embolization, and the clearest difference is hydrocele — the fluid that gathers around the testicle, which is the commonest complication after the operation and much less common after embolization. For many men that one point settles it.
Both often improve semen findings, and couples do conceive afterwards. Neither is a promise: subfertility usually has more than one cause, and this is judged with a urologist or fertility specialist rather than on the varicocele alone.
Either can. After embolization it happens slightly more often than after surgical ligation, and least often of all after microsurgical repair. It is not a dead end: embolization can simply be done again, and it also works where an operation has failed.
Yes, and for embolization you pay €0 for the procedure. Cost is not the thing to decide on here.
SOURCES
Comparisons on this page follow the CIRSE standards of practice for varicocele embolisation and the European Association of Urology guidance on varicocele in male infertility. The direction of the complication, hydrocele and recurrence comparisons comes from a 2025 meta-analysis of thirty studies. They describe the options in general; they are not advice about your case.
Bring your ultrasound, and your semen analysis if you have one.
In a consultation I scan the vein, go through why treatment is or is not indicated, and tell you plainly which route fits — doing nothing included.
After embolization most men are home the same day and back to routine in a day or two; a dull ache for a few days is usual.
