The problem

The right surgeon, the right technique, the right reason.

Varicocele affects around 15% of men - and a third of subfertile men. The technique, and who does it, changes the recurrence and hydrocele rates markedly. We fix all three questions before you commit.

  • Not sure it is needed?

    An asymptomatic grade I varicocele in a man who is not trying to conceive is usually just observed. We say so before recommending surgery.

  • Wondering which technique?

    Microsurgery has the best recurrence and hydrocele numbers. Embolisation is less invasive.

  • Fertility is the reason?

    Reviewed alongside a fertility specialist - semen analysis, hormone profile, and a clear plan for repeat testing at 3–6 months.

When it helps

When microsurgical varicocelectomy is the right step.

The situations we see most, plus the one red flag that means urgent imaging rather than an appointment.

  • Symptomatic varicocele

    A dull ache or heaviness in the scrotum, worse at the end of the day or after standing - and a palpable varicocele on examination.

  • Male infertility with abnormal semen

    Reduced sperm count, motility or morphology alongside a grade II–III varicocele - reviewed jointly with a fertility specialist.

  • Testicular size discrepancy

    Progressive shrinkage of the affected testis, or a >20% size difference in adolescents - an indication to intervene early.

  • Adolescent grade II–III varicocele

    A visible or easily palpable varicocele in a teenager with size discrepancy - managed by specialist paediatric urology.

  • Recurrence after previous surgery

    A varicocele that has come back after laparoscopic ligation or embolisation - microsurgery is often the definitive salvage.

  • Grade III (visible) varicocele

    A varicocele you can see through the scrotal skin - a classic “bag of worms” - with symptoms or infertility.

  • Left-sided is most common

    About 95% of varicoceles are left-sided, because of the angle the left gonadal vein enters the left renal vein.

  • Red flag: sudden, right-sided varicocele

    A new right-sided varicocele in an adult, or one that does not empty when lying flat, needs urgent imaging to exclude a retroperitoneal cause.

Procedure options

Microsurgery is the gold standard - but not the only option.

What each option on the table actually involves - and which fits which case.

  • Microsurgical subinguinal (Marmar / Goldstein)

    The gold standard. A 2–3 cm incision below the external ring; operating microscope; arteries, vas and lymphatics preserved; typically 8–15 veins ligated. Lowest recurrence and hydrocele.

  • Laparoscopic (Palomo variant, high ligation)

    Three keyhole ports; the internal spermatic veins are clipped at retroperitoneal level. Simpler technically, but higher hydrocele and recurrence rates than microsurgery.

  • Retroperitoneal open (Palomo)

    A small flank incision to ligate the veins high in the retroperitoneum. Largely historical - superseded by microsurgery and laparoscopic approaches.

  • Radiological embolisation (percutaneous)

    Interventional radiology, via the femoral vein up to the left gonadal vein, coils and sclerosant. Day-case under LA. Less invasive; 10–15% failure or recurrence.

  • Bilateral microsurgical varicocelectomy

    Both sides treated at the same operation when both are clinically significant - usual practice where both contribute to infertility.

  • Recurrent-varicocele microsurgery

    A more demanding operation after a previous ligation or embolisation. A dedicated andrology microsurgeon is essential.

  • Scrotal ultrasound with Doppler

    The imaging that grades the varicocele, measures both testes and confirms reflux on Valsalva - done before any decision to operate.

  • Andrology consultation only

Safety and recovery

What to expect afterwards - honestly.

Microsurgical varicocelectomy is a common, safe day-case operation. The things worth planning are your scrotal-support window, no sex for two weeks, and the repeat semen test at 3–6 months.

  • Hydrocele is the commonest complication

    A collection of fluid around the testis afterwards. Microsurgical lymphatic preservation drops the rate to 2–8%, versus 10–20% with laparoscopic ligation.

  • Recurrence is rare after microsurgery

    The varicocele reappearing is uncommon after microsurgical subinguinal (2–5%). Laparoscopic and embolisation approaches recur more often (10–20%).

  • Testicular atrophy is very rare

    The whole point of microsurgery is to see and preserve the testicular arteries. Meaningful atrophy after microsurgical varicocelectomy is a rare event.

  • Scrotal support for two to four weeks

    Snug supportive underwear reduces swelling, bruising and discomfort. Fitted before you leave the clinic.

  • No sex for two weeks

    Sex or masturbation too early is the commonest cause of pain, stitch problems and swelling in the first fortnight.

  • No heavy lifting for four to six weeks

    Walking is fine from day one. Gym, cycling and heavy lifting wait - the cord needs time to settle.

  • Semen results improve over months, not days

    Where fertility is the reason, sperm parameters typically improve by 3–6 months. We repeat the semen analysis then.

  • Success is not just anatomical

    Around 60–70% see semen improvement and 35–45% see pregnancy afterwards. Infertility is often multifactorial, and a technically perfect operation cannot fix that alone.

  • Red flags

    Fever, spreading redness, a tense hot swelling or worsening pain days after surgery are not normal - call the clinic or A&E the same day.

Reading your operation note

Your operation note in four parts. Read the last one first.

Whichever technique was used, the note the andrologist sends you keeps to the same shape.

A quiet reminder

Surgical language is precise and can read coldly - we translate it for you.

If you would like us to talk you through the note before your review, just ask.

  1. 01 Header

    Indication and side treated

    Why the operation was done - symptomatic varicocele, infertility, adolescent size discrepancy - and which side, or both.

  2. 02 Technique

    Approach, magnification and veins ligated

    Subinguinal microsurgical (Marmar / Goldstein), the magnification used, the number of veins divided, and whether arteries and lymphatics were preserved.

  3. 03 Findings

    Vein grade, testicular size, hernia sac

    The intra-operative findings - grade of venous dilation, testicular size, any patent processus vaginalis or hernia sac dealt with.

  4. 04 Impression

    Recovery, scrotal support, repeat semen date

    Read this first: expected recovery, when to return to sex and exercise, when to book a repeat semen analysis, and whether a follow-up is needed.

Frequently asked

Everything we get asked about microsurgical varicocelectomy.

Quick answers on technique choice, semen outcomes, recovery and cost.

  • What is a microsurgical varicocelectomy?

    It is the gold-standard operation for varicocele: a 2–3 cm incision below the groin, an operating microscope, and meticulous ligation of the dilated pampiniform veins while preserving the testicular arteries, the vas deferens and the lymphatics. It has the lowest recurrence and hydrocele rates of any varicocele treatment.

  • Why microsurgery rather than laparoscopic or embolisation?

    Microsurgery has recurrence rates around 2–5% and hydrocele rates of 2–8%. Laparoscopic (Palomo) ligation and radiological embolisation are less invasive in different ways, but recurrence is 10–20% and, for laparoscopic, hydrocele is 10–20%. Microsurgery is the gold standard where fertility is the reason.

  • Do I need treatment for my varicocele at all?

    Not always. An asymptomatic grade I varicocele in a man who is not trying to conceive is usually observed. Treatment is offered for symptoms, infertility with abnormal semen and a grade II–III varicocele, testicular atrophy or a significant size difference in adolescents.

  • How much does a private microsurgical varicocelectomy cost in London?

    Roughly £3,500–£6,500 for unilateral microsurgery and £5,000–£8,500 for bilateral. Laparoscopic ligation is £3,000–£5,000 and radiological embolisation £2,500–£4,000.

  • Will it improve my semen analysis and chances of conceiving?

    On average, semen parameters (density and motility) improve in about 60–70% of men after microsurgical varicocelectomy, and pregnancy rates rise by around 35–45%. Results depend on the whole fertility picture - we run the decision alongside a fertility specialist.

  • How long is the recovery and time off work?

    It is a day-case operation. Most men take 3–7 days off, wear scrotal support for 2–4 weeks, avoid sex for 2 weeks and avoid heavy lifting or cycling for 4–6 weeks.

  • What are the risks?

    The main risks are hydrocele (2–8%), recurrence (2–5%), infection, bruising and, very rarely, testicular atrophy. Chronic scrotal pain after surgery is uncommon. Failure to improve semen or achieve pregnancy despite a technically successful operation is possible because infertility is often multifactorial.

  • When should I see a doctor urgently?

    A new right-sided varicocele in an adult, or a varicocele that does not empty when you lie down, needs urgent imaging to exclude a retroperitoneal cause. After surgery, fever, spreading redness, a tense hot swelling or worsening pain warrant same-day medical review.
