Varicocele Treatment in London
A varicocele is an enlargement of the veins in the scrotum, similar to varicose veins elsewhere in the body. It is common and often causes no harm, but it can be associated with reduced sperm quality and, for some men, aching or heaviness in the scrotum.
Our consultant urologists can assess whether a varicocele may be contributing to fertility concerns or discomfort, and discuss whether treatment is appropriate.

What is a varicocele?
A varicocele is an enlargement of the network of veins that drains blood from the testicle. It is similar to varicose veins and is more commonly found on the left side of the scrotum.
Many varicoceles do not cause symptoms and do not need treatment. However, they are a recognised potential cause of reduced sperm quality and can sometimes cause a dull ache, dragging feeling or heaviness in the scrotum, particularly after standing for a long time or exercising.
A varicocele is usually identified during a physical examination and may be confirmed with an ultrasound scan. If it is affecting fertility or causing persistent discomfort, treatment may be considered.
Not every varicocele needs correcting. Your consultant will assess whether it is likely to be contributing to your symptoms or fertility concerns, then explain whether treatment is likely to be worthwhile.

A common, correctable cause
Understanding a varicocele comes down to three important points.
Common
Varicoceles are common, often occur on the left side and may cause no symptoms at all.
Can affect fertility
They can be associated with reduced sperm quality, which is why they are considered during male fertility assessment.
Treatable where appropriate
If a varicocele is causing discomfort or is likely to be affecting fertility, treatment may involve surgical repair or embolisation.
How we assess a varicocele
Accurate assessment determines whether treatment is worthwhile.
Clinical examination
A focused physical examination assesses the size and characteristics of the varicocele.
Ultrasound
Where helpful, scrotal ultrasound confirms the diagnosis and evaluates severity.
Fertility testing
If fertility is a concern, semen analysis may be performed to assess sperm parameters. Assessment considers symptoms, fertility goals and overall health.
Who varicocele treatment may suit
Treatment may be appropriate for men who:
- Have a varicocele alongside reduced sperm quality
- Are being assessed for male fertility concerns
- Experience persistent aching, heaviness or discomfort in the scrotum
- Have been advised that treatment may improve a contributing cause
- Have had consultant assessment and appropriate investigations
What to expect
- Assessment
Your consultant will discuss your symptoms and fertility history, then carry out an examination. An ultrasound scan may be arranged where it would help confirm the diagnosis or assess the varicocele. - Deciding on treatment
You and your consultant will discuss whether treatment is appropriate, taking account of fertility results, symptoms, your general health and personal priorities. - Treatment
Where treatment is recommended, the varicocele may be treated through a surgical repair or embolisation. Your consultant will explain the options, what they involve and which may be most suitable for you.

The decision to treat is made jointly after reviewing clinical findings and expectations.
Frequently asked questions
Does every varicocele need treatment?
No. Many varicoceles cause no symptoms and do not affect fertility, so treatment is not always needed. It may be considered where there is persistent discomfort or evidence that it is contributing to reduced sperm quality.
How is a varicocele diagnosed?
A varicocele is often diagnosed through a physical examination. An ultrasound scan may be used to confirm the diagnosis and assess the veins in more detail.
Will varicocele treatment improve fertility?
For some suitable men, treating a varicocele may improve sperm parameters over time. Outcomes vary and depend on factors including the severity of the varicocele and other causes of fertility difficulty. Your consultant will discuss what may be realistic for you.
How is a varicocele treated?
Treatment may involve a surgical repair or embolisation. Embolisation is an image-guided procedure that blocks the affected veins. Your consultant will explain which options may be appropriate.
