Varicocelectomy
Varicocelectomy is a surgical procedure that ligates the dilated veins of a varicocele in the scrotum or inguinal canal — relieving testicular pain, improving sperm quality parameters, and increasing the chance of natural conception in men with varicocele-associated male factor infertility.
Overview
Varicocelectomy treats a varicocele — an abnormal dilation of the pampiniform venous plexus within the spermatic cord, present in 15% of all men and in 35 to 40% of men with primary infertility — by ligating all the dilated internal spermatic veins while preserving the testicular artery, lymphatics, and vas deferens. The microsurgical inguinal or sub-inguinal approach offers the lowest recurrence rate (below 1%) and the lowest post-operative hydrocele rate compared to open high ligation or laparoscopic approaches, making it the preferred technique in specialist centres with andrology expertise. In men with clinical varicocele and abnormal semen analysis, varicocelectomy improves sperm concentration, motility, and morphology in 60 to 70% of treated patients.
Types of Varicocelectomy
Several surgical approaches offer different access routes to the dilated internal spermatic veins with varying recurrence and complication profiles.
- Microsurgical Sub-Inguinal Varicocelectomy (gold standard — optical magnification, lowest recurrence)
- Microscopic Inguinal Varicocelectomy (standard open with optical magnification)
- Laparoscopic Varicocelectomy (for bilateral varicoceles — both sides in one procedure)
- Palomo High Ligation (historical open approach — higher hydrocele rate)
- Percutaneous Embolisation (radiological approach — alternative for recurrent varicocele)
Risk Factors for Varicocele and Male Infertility
Varicocele development and its impact on fertility are influenced by anatomical and systemic factors.
- Left-sided predominance due to the vertical drainage of the left internal spermatic vein into the left renal vein
- Increased scrotal temperature from venous reflux impairing testicular thermoregulation
- Oxidative stress from venous stasis damaging sperm DNA and reducing spermatogenesis
- Bilateral varicocele causing more severe spermatogenic impairment than unilateral
- Pre-existing reduced testicular volume predisposing to greater varicocele impact
- Family history of varicocele suggesting hereditary venous valve incompetence
Varicocele Symptoms and Indications
These symptoms and fertility parameters indicate a clinical varicocele requiring specialist andrological assessment and discussion of varicocelectomy.
- Persistent dull aching or dragging scrotal pain worse with standing or exercise
- Palpable dilated veins in the scrotum on standing — the bag of worms sensation
- Visible scrotal vein prominence on the left side, particularly when straining (Valsalva manoeuvre)
- Abnormal semen analysis — reduced concentration, motility, or increased abnormal morphology
- Testicular volume asymmetry with ipsilateral testicular hypotrophy
- Scrotal vein dilation confirmed on Doppler ultrasound with reverse flow on Valsalva
- Male factor infertility with clinical or subclinical varicocele on ultrasound assessment
- Adolescent with varicocele and ipsilateral testicular growth arrest

Lymphatic preservation under magnification produces the lowest post-operative hydrocele rate
Scrotal pain relief in 70 to 80% of patients after successful varicocelectomy
Semen parameter improvements in 60 to 70% of patients developing over 3 to 6 months
Same-day day-case procedure with return to desk work within 3 to 5 days
Clinical Features
The technology, techniques and clinical approach behind our varicocelectomy.
Operating microscope magnification of 6 to 16× enables identification of every dilated vein
Testicular artery identified under magnification and confirmed patent before any vein is ligated
Intraoperative Doppler confirmation of testicular arterial flow after all vein ligations are complete
All lymphatic channels preserved under magnification to prevent post-operative hydrocele formation
Sub-inguinal approach minimises muscle division providing faster and less painful recovery
Preparation Instructions
After Varicocelectomy, wear supportive underwear and avoid vigorous activity for 2 weeks to minimise swelling and haematoma risk. Repeat semen analysis at 3 and 6 months after surgery as sperm quality improvements take at least one full spermatogenic cycle (approximately 74 days) to become apparent. Contact your urology or andrology team for increasing scrotal swelling, fever, or wound concerns after discharge. Most patients notice resolution of scrotal pain within 3 to 6 weeks of surgery.
The Procedure
Step-by-step guide to what you can expect during your varicocelectomy procedure.
Pre-Operative Semen Analysis Review
Your urologist and andrologist review the baseline semen analysis results, Doppler ultrasound grading of the varicocele, and clinical examination findings before confirming that microsurgical varicocelectomy is the most appropriate intervention for your specific presentation.
Regional or General Anaesthesia
Spinal or general anaesthesia is administered and you are positioned supine. An inguinal or sub-inguinal incision site is marked, cleaned, and draped for the microsurgical procedure which requires a completely still and bloodless operative field for accurate vessel identification.
Spermatic Cord Delivery
A small inguinal or sub-inguinal incision is made and the spermatic cord is delivered into the wound in its fascial envelope. The cord is placed on a rubber sling to allow gentle manipulation and inspection of all its constituent vessels under the operating microscope.
Microsurgical Vessel Identification
Under 6 to 16× operating microscope magnification, the dilated internal spermatic veins — typically 3 to 8 vessels — are carefully identified and distinguished from the testicular artery, the cremasteric artery, and the lymphatic channels that must all be preserved.
Individual Vein Ligation and Division
Each dilated internal spermatic vein is individually clipped with micro-clips and divided — working systematically through all cord layers until every dilated venous channel is ligated while the testicular artery, lymphatics, and vas deferens remain completely intact.
Arterial Doppler Confirmation and Closure
An intraoperative hand-held Doppler probe confirms the testicular arterial signal is strong and present before wound closure. The wound is closed in layers with absorbable sutures and a small dressing applied. Most patients are discharged the same day.
What to Expect
Varicocelectomy is performed under general or spinal anaesthesia and takes 60 to 90 minutes. A small inguinal or sub-inguinal incision is made, the spermatic cord is delivered, and under microsurgical magnification all dilated veins are individually identified and ligated while the testicular artery, lymphatics, and vas deferens are meticulously preserved. Most patients are discharged the same day.
