What happens if varicocele is left untreated?

Many varicoceles do not cause problems and can be safely monitored without immediate treatment. However, in some men, an untreated clinically significant varicocele may be associated with persistent testicular discomfort, abnormal sperm parameters, or changes in testicular growth or function. Whether treatment is needed depends on symptoms, fertility findings, testicular function, and the overall clinical assessment.

A varicocele does not always require treatment. Some men have a small or asymptomatic varicocele and never develop significant problems.

However, monitoring may be recommended because the condition can affect some men over time.

1. It May Remain Asymptomatic

Many men with varicocele have no symptoms.

If there are no fertility concerns, significant pain, or testicular changes, a urologist may recommend observation rather than immediate treatment.

2. Testicular Discomfort May Persist

A symptomatic varicocele can cause:

• Dull or aching scrotal pain.
• A feeling of heaviness.
• A dragging sensation.
• Discomfort that becomes more noticeable after prolonged standing or physical activity.

If symptoms persist or interfere with daily activities, a urological evaluation can help determine whether treatment should be considered.

3. Sperm Parameters May Be Affected

In some men, varicocele may be associated with abnormalities in:

• Sperm concentration.
• Sperm motility.
• Sperm morphology.
• Overall sperm production.

This can become relevant when a couple is experiencing difficulty conceiving.

4. Fertility Problems May Persist

An untreated clinically significant varicocele may continue to contribute to abnormal sperm parameters in some men.

However, having an untreated varicocele does not mean that infertility will definitely occur.

Other factors affecting male and female fertility also need to be considered.

5. Testicular Growth or Function May Be Affected

In adolescents, a significant varicocele may sometimes be associated with reduced growth of the affected testicle.

This is one reason testicular development may be monitored in younger patients with clinically significant varicocele.

Does an untreated varicocele always get worse?

No. A varicocele does not necessarily progress or cause complications in every patient.

The appropriate approach may be observation, especially when there are no significant symptoms or fertility concerns.

When should an untreated varicocele be reassessed?

A follow-up evaluation may be appropriate if you develop:

• Persistent or worsening scrotal pain.
• Difficulty conceiving.
• Abnormal semen analysis.
• Noticeable testicular size changes.
• Increasing scrotal swelling.
• Other new or concerning symptoms.

Your urologist can determine whether continued observation or active treatment is appropriate.

At SCI International Hospital, New Delhi, Dr. Gautam Banga, Senior Consultant Urologist and Andrologist, evaluates patients with varicocele, testicular pain, abnormal sperm parameters, and fertility concerns. He assesses whether an untreated varicocele can be safely monitored or whether treatment may be beneficial based on the patient's symptoms, fertility findings, and testicular function.
