Understanding the condition
What is a varicocele?
A varicocele is an abnormal dilation of the veins in the pampiniform plexus - the network of small veins surrounding the testicular artery inside the scrotum. Blood pools in these veins instead of draining efficiently, raising the temperature of the testicle. Sperm production is exquisitely sensitive to heat: even a 1–2°C rise above normal testicular temperature impairs spermatogenesis (sperm production) and damages sperm DNA.
Varicoceles occur predominantly on the left side (85–90%) because the left testicular vein drains into the left renal vein at a right angle - creating higher backpressure. Bilateral varicoceles are present in approximately 35–40% of cases. Right-sided varicocele alone is unusual and may warrant further investigation to exclude a retroperitoneal cause.
Palpable only on Valsalva manoeuvre (bearing down). Not visible or palpable at rest.
Palpable at rest without Valsalva. Confirmed easily on clinical examination.
Visible through the skin of the scrotum. Palpable and visible at rest - the "bag of worms" sign.
Sub-clinical varicocele (ultrasound only, not palpable) - not routinely treated. Grade alone does not determine whether surgery is needed.
Symptoms
How does a varicocele present?
Common symptoms
- Dragging heaviness or dull ache in the left scrotum - worse after standing or physical activity, better when lying flat
- Visible or palpable lump in the scrotum, often described as feeling like a "bag of worms"
- Failure to conceive - often the presenting complaint, with varicocele found on investigation
- Testicular size difference - the affected testicle may appear smaller (atrophy)
When to act
- Infertility: Abnormal semen analysis + palpable varicocele = strong indication for repair
- Pain: Significant discomfort affecting daily life or exercise, after exclusion of other causes
- Testicular atrophy: Especially in adolescents - surgery can allow catch-up growth
- Incidental finding: If semen normal and no symptoms, observation is appropriate
Investigations
What investigations are needed?
For the varicocele
- Clinical examination - cardinal test; grade assigned by physical findings
- Scrotal Doppler ultrasound - confirms reflux, measures vein diameter (>3mm), assesses testicular volume
- Testicular volume comparison - by orchidometer or ultrasound measurement
For fertility assessment
- Semen analysis (SA) - counts, motility, morphology; gold standard infertility test
- Hormones - FSH, LH, testosterone, prolactin
- Scrotal ultrasound - exclude epididymal or testicular pathology
- Female partner evaluation - essential for complete couple assessment before deciding treatment

Choosing the right approach
Microsurgical vs other techniques
| Factor | Microsurgical Dr. Nitin's technique |
Open Inguinal | Laparoscopic | Embolization |
|---|---|---|---|---|
| Recurrence rate | <1–2% | 10–15% | 5–10% | 10–15% |
| Hydrocele risk | <1% | 5–10% | 8–15% | Rare |
| Testicular artery injury | Very rare | Possible | Possible | N/A |
| Fertility outcomes | Best (evidence) | Good | Good | Moderate |
| Hospital stay | Day case/1 night | 1 night | 1 night | Day case |
| Return to work | 3–5 days | 5–7 days | 5–7 days | 2–3 days |
| General anaesthesia | Yes (or spinal) | Yes | Yes (GA only) | Local/sedation |
Have you been told to go straight to IVF?
If you have varicocele and are planning IVF, a varicocelectomy first may improve sperm parameters enough for natural conception - or significantly improve IVF success rates. International guidelines (EAU, AUA) recommend varicocele repair before IVF/ICSI when a clinical varicocele is present alongside abnormal semen.

Frequently asked questions
Varicocele - your questions answered
No. Varicocele surgery is recommended when it is associated with male infertility (abnormal semen analysis), significant pain or discomfort, or testicular atrophy (shrinkage) in adolescents. If a varicocele is found incidentally and semen parameters and testicular volume are normal, careful observation without surgery is reasonable. Dr. Nitin assesses each case individually - not every varicocele needs an operation.
Varicocele is the most common correctable cause of male infertility, found in approximately 35–40% of men presenting with infertility. Elevated testicular temperature caused by sluggish venous blood flow damages sperm production (spermatogenesis). After surgical repair (varicocelectomy), semen parameters improve in 60–70% of men and natural conception rates improve significantly. Varicocele repair should be evaluated before proceeding to IVF/ICSI, as it may allow natural conception or improve IVF outcomes.
Microsurgical varicocelectomy uses a surgical microscope (×6–25 magnification) via a small sub-inguinal incision. The magnification allows precise identification and preservation of the testicular artery, lymphatics, and vas deferens - while ligating all abnormal veins. This approach has the lowest recurrence rate (<1–2%), lowest complication rate (no hydrocele, no testicular atrophy), and best fertility outcomes compared to open inguinal, laparoscopic, or embolization approaches. It is Dr. Nitin's preferred technique.
Microsurgical varicocelectomy takes approximately 30–45 minutes per side under general or spinal anaesthesia. It is performed as a day-case or with one overnight stay. You can return to desk work in 3–5 days and light physical activity in 2 weeks. Heavy lifting and strenuous exercise should be avoided for 4 weeks. There is minimal discomfort - most patients manage with paracetamol only. Semen analysis is typically repeated at 3 and 6 months post-surgery to assess improvement.
Semen parameters typically improve progressively over 3–6 months after varicocelectomy, as it takes approximately one full spermatogenic cycle (74 days) for new sperm to be produced. Improvement in sperm count, motility, and morphology is seen in 60–70% of men. Most couples attempting natural conception are advised to try for 12 months post-surgery before considering IVF/ICSI. If parameters have not improved at 6 months or there are other fertility factors, assisted reproduction can be considered alongside the varicocele repair.
Recurrence depends on technique. Open inguinal repair: 10–15% recurrence. Laparoscopic: 5–10% recurrence. Microsurgical sub-inguinal varicocelectomy: <1–2% recurrence. The microsurgical approach has the lowest recurrence because the high magnification allows all abnormal veins to be identified and tied, including small periarterial veins that are missed at lower magnification. Hydrocele (fluid accumulation around the testis) - a common complication of other techniques - occurs in <1% with the microsurgical approach because the lymphatics are preserved.
Varicocele is graded by physical examination and confirmed by scrotal ultrasound with Doppler. Grade I: only palpable on Valsalva manoeuvre (bearing down). Grade II: palpable at rest without Valsalva. Grade III: visible through the skin, palpable at rest. Sub-clinical varicocele: detected only on ultrasound, not palpable - these are generally not treated. Grade is one factor in the decision to treat, alongside semen parameters and symptoms. All grades can affect fertility; the decision to operate is based on the overall clinical picture, not grade alone.
