Introduction
Many men notice an unusual sensation or heaviness near the testis but delay seeking medical advice. Often described as a “bag of worms” feeling, this symptom may indicate an underlying condition called varicocele. Understanding it early can help protect long‑term testicular health.

What Is Varicocele?
Varicocele occurs when veins surrounding the testis become abnormally enlarged due to poor blood drainage. It is similar in mechanism to varicose veins seen in the legs.
Common Symptoms
- Heaviness or dragging sensation
- Dull discomfort or pain
- Symptoms worsening after standing
- Visible or palpable enlarged veins
Some men may have no symptoms and discover it incidentally.
Why Varicocele Should Not Be Ignored
While not always dangerous, untreated varicocele can increase the risk of:
- Reduced testicular function
- Fertility issues in selected individuals
Early evaluation helps in risk assessment and management planning.
Role of Imaging
Ultrasound plays a crucial role in confirming varicocele, assessing vein size, and evaluating blood flow. Accurate imaging supports informed, patient‑specific decisions.
Radiologist’s Perspective
From an imaging standpoint, timely diagnosis allows men to understand their condition clearly—without fear or assumptions—and consider appropriate next steps with their clinician.
