Male Fertility
Varicocele
An enlargement of veins within the scrotum, similar to varicose veins elsewhere in the body. It is a common finding, and not every varicocele requires treatment.
How it’s found
Clinical vs. Ultrasound-Detected
A varicocele may be found on physical examination — a clinical varicocele — or only be visible on ultrasound, known as subclinical. This distinction matters, since not every ultrasound finding carries the same significance.
Fertility and function
Relevance to Fertility and Testicular Function
Varicoceles can, in some men, affect semen parameters and testicular function over time. Many men with a varicocele have normal fertility, and its presence alone does not predict infertility.
Symptoms
Pain Is Not Universal
Some men experience discomfort or a dragging sensation, particularly after standing for long periods. Many others have no symptoms at all, and the varicocele is found incidentally.
Management
Observation vs. Intervention
Many varicoceles are simply observed, particularly when there are no symptoms and fertility is not currently a concern. Intervention may be considered where there is pain, a clear effect on semen parameters, or testicular size concerns.
An imaging finding, not a verdict
Findings, not decisions in isolation.
An ultrasound finding on its own is not treated in isolation. Whether intervention is appropriate depends on symptoms, fertility goals, semen analysis and clinical examination together — assessed as a whole, not from imaging alone.
