Chronic Testicle Pain: Causes and Best Treatment Options

Chronic Testicle Pain, also referred to as Chronic Scrotal Content Pain (CSCP), is a persistent discomfort in the scrotal area that lasts for at least three months. This condition can significantly impact a man's daily life, affecting activities and overall well-being.

What Are the Main Causes of Chronic Testicle Pain?

• Idiopathic Causes: In up to 50% of cases, the exact cause of CSCP is unknown, making diagnosis and treatment particularly challenging.
• Recognisable Causes: These include conditions such as varicocele (enlarged veins in the scrotum), epididymitis (inflammation of the epididymis), spermatocele (cysts), infections, and testicular torsion (twisting of the testicles).
• Nerve-Related Pain: The pain may stem from nerve damage or hypersensitivity, particularly following an injury to the scrotal area. The nerves involved include the iliohypogastric, ilioinguinal, genitofemoral, and pudendal nerves.

How is Chronic Testicle Pain Diagnosed? Key Steps You Should Know

Proper diagnosis is crucial to determine the underlying cause of the pain. The diagnostic process includes:

• Detailed Medical History: Understanding the pain's duration, intensity, and any factors that aggravate or alleviate it is essential.
• Physical Examination: A thorough examination of the scrotum and surrounding areas is crucial.
• Imaging Studies: High-resolution scrotal ultrasound and Doppler imaging are recommended to rule out other conditions such as testicular tumours or varicocele.
• Nerve Block Test: A spermatic cord block (SCB) may be used to determine if the pain originates from the scrotal nerves.

What Are the Best Treatment Options for Chronic Testicle Pain?

Non-Surgical Treatments for Chronic Testicle Pain

1. Medications for Testicle Pain Relief:
   • Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): These are the first line of treatment, with ibuprofen or celecoxib commonly prescribed.
   • Tricyclic Antidepressants (TCAs): Medications like amitriptyline may be added if NSAIDs are ineffective. Success rates for pain improvement range from 50% to 67%.
   • Anticonvulsants: Drugs such as gabapentin or pregabalin can help manage nerve-related pain. These have shown success in 61% to 66% of patients.
2. Nerve Block with Local Anaesthetic and Steroid:
   • Spermatic Cord Block (SCB): This is both a diagnostic and therapeutic intervention. It involves injecting a local anaesthetic (such as bupivacaine) into the spermatic cord, sometimes combined with a steroid (like triamcinolone acetonide) to disrupt the pain pathway.
   • Effectiveness: While this block can provide temporary relief, especially when performed in a series (typically every 2 weeks for 4-5 sessions), long-term effectiveness is limited, particularly in cases where pain has persisted for over 6 months.
3. Physical Therapy for Testicle Pain:
   • Pelvic Floor Physical Therapy (PFPT): This is beneficial, particularly for those with pelvic floor dysfunction or myofascial pain. Studies show that PFPT can lead to significant pain reduction in 50% to 63% of patients.
4. Alternative Non-Surgical Interventions:
   • Acupuncture: Some patients find relief through alternative therapies like acupuncture, though success rates are variable and less documented.
   • Psychological Support for Chronic Pain: Addressing underlying psychological factors such as anxiety or depression can be crucial, especially when no organic cause is found.

Surgical Treatments for Chronic Testicle Pain

If non-surgical treatments fail to provide relief, surgery may be considered. Options include:

1. Microdenervation of the Spermatic Cord (MDSC):
   • This is a relatively new surgical approach aimed at severing the nerves responsible for the pain while preserving blood vessels and lymphatics.
   • Success Rates: Studies show complete pain relief in 71% to 97% of cases.
2. Epididymectomy for Localised Testicle Pain:
   • This involves the removal of the epididymis and is typically recommended when the pain is localised to this area.
   • Success Rates: Reports indicate pain relief in 50% to 92% of cases, especially when a structural abnormality is present.
3. Vasectomy Reversal for Post-Vasectomy Pain Syndrome:
   • In cases of post-vasectomy pain syndrome (PVPS), reversing the vasectomy can relieve the pain.
   • Success Rates: Complete pain resolution is observed in 50% to 69% of cases, with up to 93% experiencing some degree of pain improvement.
4. Orchiectomy as a Last Resort:
   • As a last resort, the removal of the testicle may be considered.
   • Success Rates: Relief of pain is achieved in 55% to 73% of cases, but some studies show continued pain in up to 80% of patients, making this a less favourable option.

Final Thoughts on Managing Chronic Testicle Pain

Chronic testicle pain can be a debilitating condition, but with a comprehensive approach that includes both medical and psychological evaluation, effective treatment is possible. The choice of treatment should be personalised based on the underlying cause, the patient's symptoms, and their response to initial therapies. For those whose pain persists despite non-surgical interventions, surgical options such as MDSC offer hope for long-term relief.
