In clinical practice, a physical examination of the scrotum can sometimes reveal what feels like a "bag of worms." This description, while unusual, is the classic sign of a condition known as a varicocele. A varicocele is essentially a varicose vein an enlargement of the veins within the scrotum . It is a relatively frequent finding, particularly in young men, and while often harmless, it can be a source of discomfort and, in some cases, can have significant implications for fertility .
My goal today is to provide a clear, medical overview of what a varicocele is, why it happens, and what the modern approaches to management and treatment are.
The Underlying Cause: A Problem of Plumbing
To understand a varicocele, it helps to understand the anatomy of the spermatic cord. This cord holds up each testicle and contains the arteries, nerves, and veins that support it. In healthy veins, tiny one-way valves ensure that blood flows up and away from the testicles, back toward the heart .
A varicocele develops when these valves fail or become faulty . When a valve doesn't close properly, blood can flow backward and pool in the vein, causing it to stretch and enlarge . This process tends to happen slowly over time, and for anatomical reasons, it occurs most often in over 80% of cases on the left side . The left testicular vein's longer path and connection angle make it more susceptible to this backflow pressure .
Signs, Symptoms, and Impact
A large number of varicoceles produce no symptoms at all and may only be discovered during a routine physical or fertility evaluation . When symptoms do occur, they can include:
- A Dull, Aching Pain: A dragging or aching discomfort in the scrotum is a key symptom. This pain often worsens after standing for long periods or with physical exertion and typically feels better when lying down .
- Visible or Palpable Swelling: A noticeable lump or swelling above the testicle, which may look or feel like a collection of worms, is a primary sign .
- Testicular Atrophy: The affected testicle may be smaller than the other. The impaired circulation and increased temperature from the pooled blood can hinder testicular growth or cause it to shrink .
The most significant potential impact of a varicocele is on male fertility. The pooling of blood raises the temperature within the scrotum. The testicles require a cooler-than-body temperature environment for optimal sperm production (spermatogenesis). The elevated temperature caused by a varicocele can impair both the quantity and quality of sperm, potentially leading to difficulties with conception .
Diagnosis: A Straightforward Clinical Evaluation
Diagnosing a varicocele is typically straightforward.
- Physical Examination: A doctor will examine the scrotum while the patient is standing, as the varicocele is more prominent in this position . You may be asked to perform the Valsalva maneuver (taking a deep breath, holding it, and bearing down), which increases internal pressure and makes even smaller varicoceles easier to feel .
- Scrotal Ultrasound: In some cases, an ultrasound may be used. This imaging test provides a detailed view of the spermatic veins, allowing the doctor to confirm the diagnosis and measure the size of the enlarged veins .
Once diagnosed, varicoceles are often graded on a scale of 1 (smallest) to 3 (largest) .
Treatment: When Is It Necessary?
Crucially, not every varicocele requires treatment . Intervention is generally recommended only when the varicocele is causing:
- Significant or persistent pain .
- Documented male infertility .
- Evidence that the testicle on the affected side is not growing properly or is shrinking (testicular atrophy) .
For mild discomfort, conservative measures like wearing supportive underwear (briefs or a jockstrap) and using over-the-counter anti-inflammatory pain relievers can be effective .
When treatment is indicated, the goal is to block off the affected veins, redirecting blood flow through healthy ones. The main options are:
- Surgical Varicocelectomy: A surgeon makes a small incision and ligates (ties off) the enlarged veins. This can be done through an open, laparoscopic (keyhole), or microsurgical approach. Microsurgery, which uses a high-powered microscope, allows for very precise identification and preservation of important structures like the testicular artery .
- Percutaneous Embolization: A less invasive, non-surgical option performed by an interventional radiologist. A small catheter is inserted into a vein (usually in the groin) and guided to the varicocele. Small coils or a solution are then deployed to block the vein from the inside, causing it to shrink .
If you have been diagnosed with a varicocele, the path forward is a conversation with your urologist. Together, you can assess your symptoms, fertility goals, and overall health to determine whether watchful observation or active treatment is the right course of action for you.
