What is a varicocele?

A varicocele is an enlargement of veins around the testicle. Many men have no symptoms or fertility problems. A urologist assesses it by examination; ultrasound may help when the findings are unclear. [1, 2]

When might treatment help?

For fertility, repair may be considered when a varicocele is felt on examination, semen results are abnormal and the couple is having difficulty conceiving. A finding on ultrasound alone is usually not a reason for fertility surgery. Both partners’ circumstances matter. [1]

What if the main concern is pain?

Persistent discomfort may justify a treatment discussion after assessment for other causes. Surgery does not guarantee pain relief. [2, 3]

What does microsurgery involve?

Through a small groin incision, the surgeon uses a microscope to identify and close abnormal veins. Observation and radiological embolisation may be alternatives. Risks include bleeding, infection, recurrence, fluid around the testicle and, rarely, injury to its blood supply. [2, 3]

What should I expect afterwards?

Recovery instructions are individual. If surgery is for fertility, follow-up semen testing is commonly arranged around three months. Improvement and pregnancy are not guaranteed. Bring previous semen analyses and imaging to your consultation. [2, 3]
