How is varicocele diagnosed?

Varicocele is usually diagnosed through a physical examination of the scrotum, often while standing and sometimes while straining. If the diagnosis is unclear or further evaluation is needed, a scrotal Doppler ultrasound may be recommended. In men with fertility concerns, a semen analysis and selected hormone tests may also be performed.

The diagnosis of varicocele begins with a detailed medical history and physical examination by a urologist or andrologist.

The doctor evaluates the scrotum and testicles for enlarged veins, swelling, tenderness, and differences in testicular size.

1. Physical Examination

During the examination, the doctor may examine the scrotum while you are:

• Standing.
• Lying down.
• Performing a gentle straining maneuver when appropriate.

A larger varicocele may be visible or palpable during examination.

2. Scrotal Doppler Ultrasound

A scrotal Doppler ultrasound may be recommended when the physical examination is inconclusive or when the doctor needs additional information.

It can help assess:

• Testicular structure.
• Blood flow within the scrotal veins.
• Enlargement of the veins.
• Reflux of blood through the veins.
• Other possible causes of scrotal symptoms.

3. Semen Analysis

If fertility is a concern, a semen analysis may be recommended.

It evaluates parameters such as:

• Sperm concentration.
• Sperm motility.
• Sperm morphology.
• Semen volume.

The results can help determine whether the varicocele may be associated with abnormal sperm parameters.

4. Hormone Testing

Hormonal tests may be considered when there are concerns about:

• Low testosterone.
• Abnormal sperm production.
• Reduced sexual function.
• Other signs of hormonal imbalance.

Depending on the clinical situation, the doctor may evaluate testosterone and other reproductive hormones.

Does every varicocele need an ultrasound?

No. A clinically obvious varicocele can often be diagnosed through physical examination.

However, ultrasound may be useful when the diagnosis is uncertain, symptoms require further evaluation, or the doctor needs to assess other scrotal conditions.

Can varicocele be diagnosed at home?

No reliable home test can replace a professional examination.

If you notice enlarged scrotal veins, swelling, testicular discomfort, or fertility problems, a urologist can determine whether these symptoms are caused by varicocele or another condition.
