Varicocele

Reviewed by Dr Abhishek Kumar on 23 September 2026

A varicocele is an enlargement of the veins that drain the testicle, similar to a varicose vein elsewhere in the body, most often on the left side because of how that vein joins the kidney vein. Many men have one and never notice it; in others it is found during a fertility work-up or shows up as a dull ache or heaviness in the scrotum, especially after standing for long periods.

Book a private consultation

A varicocele is common: a study of over 7,000 healthy young men across six European countries found one in more than a third of them, and men with a varicocele had, on average, lower sperm concentration and total sperm count and modestly different reproductive hormone levels than men without one^[1]. Not every varicocele needs treatment — the decision turns on its size, whether it causes pain, and above all whether the semen analysis is abnormal in a man whose partner is trying to conceive. A consultation in any of the practice's three systems opens with that same physical assessment, because a varicocele is a finding in the veins themselves that no remedy closes.

When to see a doctor

Seek care without delay if

Sudden, severe testicular pain or swelling, which needs same-day emergency assessment to rule out testicular torsion.
A new hard lump in a testicle separate from the usual soft, twisted feel of a varicocele.
Testicular swelling together with fever or feeling generally unwell.
A noticeable, rapid change in testicle size compared with before.

Book a consultation when

Atypical features need assessment: a varicocele that does not reduce when lying down, develops suddenly, or is isolated to the right side can warrant further evaluation because these features may suggest a secondary cause.
A dull ache or heaviness in the scrotum, especially after standing for long periods, that affects daily life.
A varicocele found on examination together with an abnormal semen analysis, to discuss whether treatment is likely to help.
No conception after 12 months of regular, unprotected sex, with a known or suspected varicocele.
A varicocele noticed for the first time as an adult, for a baseline assessment even without symptoms.

Some symptoms need prompt care: when to seek emergency or specialist care.

How each system of medicine approaches Varicocele

System	Approach	Typical review period
Modern medicine	A physical examination is the main way a varicocele is assessed, with ultrasound used when the examination is uncertain or another cause needs to be excluded. Semen analysis and, when indicated, hormone tests help determine whether the varicocele may be affecting fertility.	Pain, when present, often eases within a few weeks of repair; any effect on semen quality is judged on a repeat analysis at around 3 months, since that is how long a new batch of sperm takes to mature.	Limited or mixed evidence Evidence suggests that varicocele repair may improve fertility outcomes in selected men, particularly those with a clinically palpable varicocele and abnormal semen parameters, but the certainty of the evidence is limited.

Modern medicine for Varicocele

Definitive treatment is surgical repair (microsurgical varicocelectomy) or radiological embolization, both aimed at closing off the abnormal veins so blood no longer pools around the testicle. Neither is normally offered for a varicocele that causes no pain and sits alongside a normal semen analysis.

When repair may help: A Cochrane review found evidence suggesting that surgery or embolization may increase the chance of spontaneous pregnancy in selected subfertile men with a clinically palpable varicocele and abnormal semen analysis, although the certainty of the evidence was low^[2].
When repair is less clearly beneficial: Evidence does not establish a clear fertility benefit from treating a varicocele detected only on ultrasound or one associated with normal semen parameters^[2].
It is about more than size alone: A large European cohort found associations between varicocele and lower sperm concentration and total sperm count, along with differences in some reproductive hormone levels^[1]. Treatment decisions therefore consider the clinical examination, symptoms and semen parameters rather than varicocele size alone.
Recurrence and risk are discussed beforehand: like any procedure, repair carries a risk of recurrence or other complications, and this is set out by the surgeon before a decision is made.

What is known and what remains uncertain

Known: A varicocele is common, and most men who have one never develop a fertility or pain problem from it.
Known: Repair is linked to a better chance of spontaneous pregnancy specifically when the man has a palpable varicocele and an abnormal semen analysis.
Known: Trial evidence does not support treating a varicocele seen only on ultrasound, or one that sits alongside a normal semen analysis.
Uncertain: The overall certainty of the pregnancy-rate evidence behind repair was rated low by the systematic review that reported it.
Uncertain: Whether an individual man's semen quality will improve after repair is not promised and is confirmed only by a later semen analysis.

Questions to ask your doctor

What grade is my varicocele, and does that affect whether treatment is needed?
Does my semen analysis result actually support having repair done?
What are the realistic chances repair improves our chances of conceiving in our situation?
What does the procedure involve, and what is recovery usually like?
What are the risks of recurrence or complications with repair?
If I have no symptoms and a normal semen analysis, is it reasonable to simply monitor?

Frequently Asked Questions

Does every varicocele need surgery?

No. Many men have a varicocele with no symptoms and a normal semen analysis, and the trial evidence does not support treating it in that situation^[2]. Treatment is usually reserved for pain, or for a varicocele linked to an abnormal semen analysis in a man whose partner is trying to conceive.

Can a varicocele really affect fertility?

It can. A large study found men with a varicocele had, on average, a lower sperm concentration and total sperm count than men without one^[1], though not every man with a varicocele has a fertility problem.

What does treatment actually involve?

Either a microsurgical repair (varicocelectomy) or a radiological procedure (embolization) that closes off the abnormal veins. Both are usually day procedures, with recovery measured in days to a couple of weeks.

Will semen quality definitely improve after repair?

Not for every man. Trial evidence shows a benefit to pregnancy chances specifically in couples where the semen analysis was abnormal beforehand^[2], but individual results vary, and any change is confirmed with a repeat semen analysis rather than assumed.

Is there an Ayurvedic or homeopathic treatment for a varicocele?

A consultation in any system starts with the same physical assessment, because a varicocele is a structural finding in the veins. Where repair is indicated, it is a surgical or radiological procedure, and no remedy in any system closes a vein.
