Varicocele embolization is an interventional radiology procedure in which the testicular vein causing the varicocele is blocked from inside through a thin catheter, with no incision in the scrotum. Its aim is to stop blood flowing back into the spermatic cord veins, easing pain and improving semen parameters in suitable patients.
It is usually performed under local anaesthesia with light sedation. The doctor inserts a catheter through a vein in the upper thigh or neck, guides it under X-ray to the affected vein and closes it with tiny metal coils or a sclerosing agent.
The procedure generally takes about an hour, and the patient goes home the same day after a short rest, resuming most activities within a day or two while avoiding strenuous effort for a few days. Semen improvement is assessed three to six months after the procedure.
The final cost is set after a medical consultant reviews your case and photos.

It treats the varicocele without a scrotal incision and usually without general anaesthesia, allows a quick return to activity, can treat both sides in one session, and is a useful option when a varicocele recurs after surgery.
Men with a painful varicocele or one associated with abnormal semen and difficulty conceiving who prefer to avoid surgery, or whose varicocele returned after previous surgery, after joint assessment by a urologist and an interventional radiologist.
A colour Doppler ultrasound and blood tests including kidney function are needed, and any contrast allergy must be reported. Never stop any medicine on your own, such as blood thinners; your doctor decides.
After numbing the entry site, a catheter is placed in the vein, contrast is injected to map the veins, coils or sclerosant are placed to close the faulty vein, and the catheter is removed with pressure on the site.
Usually only the local anaesthetic sting and mild pressure are felt; slight discomfort in the flank or scrotum may follow and eases with painkillers.
Most men return to work within a day or two, avoid vigorous sport and heavy lifting for a few days, and resume intercourse when the doctor advises.
Pain may ease within weeks and semen improvement is measured after three to six months. Results are lasting for many men, though recurrence or technical failure can occur in some cases.
Possible issues include bruising at the entry site, inflammation of the treated vein, contrast reactions and, rarely, coil migration, as well as radiation exposure. No result can be guaranteed.
Embolization is less invasive with faster recovery and no incision, while microsurgery has a very low recurrence rate and needs no radiation; the better choice depends on vein anatomy and patient preference.
Travel is usually possible two to three days after the procedure if the entry site has healed well; your doctor confirms the right time.
