Are Varicoceles Painful?
Yes, varicoceles can cause pain in approximately 2-10% of affected men, typically described as a dull, aching, or throbbing pain in the testicle, scrotum, or groin that worsens with prolonged standing and physical activity. 1
Clinical Presentation of Varicocele Pain
Varicoceles affect up to 15% of males and are the most common diagnosis in infertile men 2. When painful, the discomfort is characterized by:
- Pain quality: Typically described as a dull, aching, or throbbing pain; rarely acute, sharp, or stabbing 1
- Location: Testicle, scrotum, or groin area 1
- Timing: Often worse at the end of the day, especially after prolonged standing 2
- Relief factors: Usually improves when sitting or lying down with leg elevation 2
Mechanisms of Varicocele Pain
Several mechanisms may contribute to pain in varicoceles:
- Compression of surrounding neural fibers by dilated venous complex
- Elevated testicular temperature
- Increased venous pressure
- Tissue hypoxia
- Oxidative stress
- Hormonal imbalances
- Reflux of toxic metabolites from adrenal or renal origin 1
Diagnosis
Diagnosis of painful varicocele involves:
- Physical examination: Palpation of the scrotum while the patient performs Valsalva maneuver
- Grading system:
- Grade I: Palpable only during Valsalva
- Grade II: Palpable without Valsalva
- Grade III: Visible through scrotal skin 3
- Color Doppler ultrasound: Confirms diagnosis and assesses reflux 4
Management Algorithm
First-Line: Conservative Management
All patients with painful varicoceles should initially receive conservative treatment:
- Scrotal support/athletic supporter
- Non-steroidal anti-inflammatory drugs
- Limiting prolonged standing
- Avoiding heavy lifting
- Weight loss if obese 2, 1
Second-Line: Interventional Treatment
If conservative measures fail after 3-4 weeks, consider interventional options:
Surgical varicocelectomy:
Endovascular therapy:
- Gonadal vein embolization using coils or sclerosants
- 87% complete pain relief at 39 months in one review 2
Predictors of Successful Pain Relief
Factors associated with better outcomes after varicocelectomy:
- Higher grade varicocele (Grade II-III)
- Characteristic dull, aching pain
- Duration of pain less than 6 months
- Previous failure of conservative management
- Use of microsurgical techniques 1
Important Caveats
Surgical success does not always translate to pain relief: Pain may persist even when no varicoceles are detected postoperatively 5
Rule out other causes: Consider other sources of scrotal pain such as epididymitis, orchitis, testicular torsion, or referred pain
Special consideration for right-sided varicoceles: Isolated right varicoceles are uncommon and may warrant evaluation for underlying abdominal pathology, although routine abdominal imaging is not recommended for all right-sided varicoceles 2
Nutcracker syndrome: Consider this diagnosis in patients with varicocele and hematuria, as compression of the left renal vein can lead to secondary varicocele formation 6
