Understanding Varicocele Embolisation: Benefits and Procedure Explained

Varicocele embolisation is a minimally invasive treatment option for varicoceles, a common condition affecting the veins in the scrotum. Many men experience discomfort, fertility issues, or testicular atrophy due to varicoceles, and embolisation offers an effective alternative to surgery. This post explains what varicocele embolisation involves, its benefits, and what patients can expect before, during, and after the procedure.
What Is a Varicocele?
A varicocele is an enlargement of the veins within the scrotum, similar to varicose veins that occur in the legs. These veins, called the pampiniform plexus, become dilated and can cause blood to pool rather than flow efficiently. Varicoceles are quite common, affecting about 15% of men overall and up to 40% of men with infertility problems.
Varicoceles often develop during puberty and may not cause symptoms initially. However, they can lead to:
A dull or aching pain in the scrotum
Visible or palpable enlarged veins
Testicular shrinkage (atrophy)
Reduced sperm quality and fertility issues
How Does Varicocele Embolisation Work?
Varicocele embolisation is a procedure that blocks the abnormal veins causing the varicocele. A radiologist inserts a thin catheter into a vein, usually in the groin or neck, and guides it to the affected veins in the scrotum using real-time X-ray imaging (fluoroscopy). Once positioned, the doctor releases small coils or a special medical glue to close off the faulty veins.
By blocking these veins, blood flow is redirected to healthy veins, relieving pressure and improving circulation in the testicles. This helps reduce pain, prevent further damage, and can improve fertility.
Benefits of Varicocele Embolisation
This procedure offers several advantages compared to traditional surgery:
Minimally invasive: No large incisions are needed, only a small puncture site.
Outpatient treatment: Most patients go home the same day.
Quick recovery: Patients often return to normal activities within a few days.
Lower risk of complications: Less chance of infection or damage to surrounding tissues.
Effective symptom relief: Many men experience reduced pain and improved fertility.
Repeatable: If needed, embolisation can be repeated without major surgery.
Who Is a Good Candidate?
Varicocele embolisation is suitable for men who have:
Pain or discomfort from a varicocele that affects daily life
Infertility linked to varicocele confirmed by a fertility specialist
Testicular atrophy associated with varicocele
Failed or declined surgical treatment
Before the procedure, patients undergo a thorough evaluation including physical examination, scrotal ultrasound, and sometimes semen analysis. The doctor discusses the benefits and risks to ensure embolisation is the right choice.
What to Expect During the Procedure
The embolisation procedure typically takes 30 to 60 minutes and involves these steps:
Preparation: The patient lies on an X-ray table. Local anesthesia numbs the catheter insertion site.
Catheter insertion: A small needle punctures a vein in the groin or neck. A catheter is threaded through the vein to the varicocele.
Imaging guidance: Fluoroscopy helps the doctor see the veins and position the catheter precisely.
Embolisation: Coils or glue are released to block the abnormal veins.
Completion: The catheter is removed, and pressure is applied to stop bleeding.
Patients usually feel minimal discomfort during the procedure. Sedation may be offered to help with relaxation.
Recovery and Aftercare
After embolisation, patients rest for a few hours before going home. Some soreness or bruising at the insertion site is normal. To support healing:
Avoid heavy lifting or strenuous exercise for about a week.
Wear supportive underwear to reduce scrotal swelling.
Take pain medication as recommended.
Follow up with the doctor for ultrasound or semen analysis if needed.
Most men notice symptom improvement within weeks. Fertility benefits may take several months to appear as sperm production improves.
Possible Risks and Complications
Varicocele embolisation is generally safe, but like any procedure, it carries some risks:
Minor bleeding or bruising at the catheter site
Infection (rare)
Allergic reaction to contrast dye
Coil migration (very rare)
Recurrence of varicocele if veins reopen
Doctors take precautions to minimize risks and monitor patients closely during and after the procedure.
Comparing Embolisation to Surgery
Surgical varicocele repair involves making an incision to tie off the affected veins. While effective, surgery has longer recovery times and higher risks of complications such as infection or hydrocele (fluid buildup).
Embolisation offers a less invasive option with similar success rates. It is especially useful for men who want to avoid surgery or have had unsuccessful surgery before.
Real-Life Example
John, a 32-year-old man, struggled with scrotal discomfort and low sperm count. After diagnosis, he chose varicocele embolisation. The procedure took 45 minutes, and he went home the same day. Within a month, his pain reduced significantly. Six months later, his sperm quality improved, and he and his partner began trying for a family with renewed hope.
Final Thoughts
Varicocele embolisation provides a safe, effective way to treat varicoceles without surgery. It relieves pain, protects testicular health, and may improve fertility. Men experiencing symptoms or fertility challenges linked to varicoceles should discuss this option with their healthcare provider.
If you suspect you have a varicocele or want to explore treatment options, consult a specialist who can guide you through diagnosis and care. Taking action early can protect your reproductive health and quality of life.
