Orchitis

Orchitis is the inflammation of one or both testicles. It can be acute or chronic and is often caused by viral or bacterial infections. Mumps is a common viral cause, particularly in unvaccinated individuals. Bacterial orchitis is usually a complication of sexually transmitted infections like gonorrhea or chlamydia, or urinary tract infections. Symptoms can range from mild discomfort to severe testicular pain, swelling, and fever. Prompt diagnosis and treatment are crucial to prevent complications such as testicular atrophy, infertility, and chronic pain.

• Viral Infections: The most common viral cause is the mumps virus, especially in pre-pubertal and post-pubertal males. Other viruses like coxsackievirus, echovirus, adenovirus, and parvovirus B19 can also cause orchitis.

• Other Causes: While less common, orchitis can also result from trauma, surgical procedures involving the genitourinary tract, autoimmune disorders, or inflammatory conditions.

Orchitis typically develops when an infection spreads to the testicle. In viral orchitis, such as mumps, the virus can spread hematogenously (through the bloodstream) to the testicular tissue. In bacterial orchitis, infection usually ascends from the urethra or prostate, involving the epididymis first (epididymo-orchitis) before spreading to the testis. The inflammatory process triggers an influx of inflammatory cells, leading to edema, hyperemia, and disruption of the testicular parenchyma. This can damage the seminiferous tubules, impairing spermatogenesis, and can also affect Leydig cells, which produce testosterone. Chronic inflammation can lead to fibrosis and testicular atrophy.

Orchitis can affect individuals of any age, but it is more common in young adults and adolescents. Mumps orchitis is a significant concern in unvaccinated populations, with up to 30-50% of post-pubertal males infected with mumps developing orchitis. Bacterial orchitis is more prevalent in sexually active men aged 18-35 years and in older men with UTIs or prostatic hyperplasia. The incidence of sexually transmitted orchitis has increased with the rise in STIs.

• Unvaccinated status for mumps
• Unprotected sexual activity
• History of sexually transmitted infections (STIs)
• History of urinary tract infections (UTIs)
• Indwelling urinary catheterization
• Prostatectomy or other genitourinary surgery
• Bladder outlet obstruction (e.g., due to benign prostatic hyperplasia)
• Immunosuppression
• Recent groin surgery or trauma
• Cryptorchidism (undescended testicle)

A. Early Symptoms

• Sudden onset of testicular pain


• Swelling of the scrotum B. Common Symptoms


• Moderate to severe testicular pain, which may radiate to the groin or lower abdomen


• Scrotal swelling and redness


• Fever and chills


• Nausea and vomiting


• General malaise and fatigue


• Painful urination (dysuria)


• Discharge from the penis (in cases of STI-related orchitis) C. Advanced Symptoms


• Enlarged and tender testicle


• Heaviness in the scrotum


• Epididymal tenderness (if epididymo-orchitis) D. Emergency Symptoms


• Severe, unrelenting scrotal pain


• High fever with chills


• Signs of sepsis (e.g., rapid heart rate, low blood pressure, confusion)

• Vital Signs: Fever, tachycardia.
• Inspection: Scrotal erythema (redness), edema (swelling), and possibly a hydrocele.
• Palpation: A swollen, warm, and exquisitely tender testicle. The epididymis may also be swollen and tender. The spermatic cord might be thickened.
• Auscultation: Bowel sounds may be decreased if nausea and vomiting are present.

A. Clinical Assessment
A detailed history of symptoms, onset, sexual history, vaccination status, and any recent infections is crucial. B. Laboratory Testing
Urine analysis, urine culture, STI testing (e.g., nucleic acid amplification tests for gonorrhea and chlamydia), and blood tests for inflammatory markers. C. Imaging Studies
Scrotal ultrasound is the primary imaging modality to differentiate orchitis from testicular torsion and assess testicular size, echogenicity, and blood flow. D. Functional Tests
Not typically applicable for diagnosis, but assessment of testicular function may be done if infertility is a concern. E. Biopsy Findings
Rarely performed for diagnosis unless malignancy is suspected. If done, it may show inflammatory cell infiltration, interstitial edema, and tubular damage. F. Genetic Testing
Not typically indicated for orchitis. G. Differential Diagnosis
Testicular torsion, epididymitis, testicular trauma, incarcerated inguinal hernia, Fournier's gangrene, testicular tumor, hydrocele, varicocele, spermatocele.

Test Name
Urine Analysis
Type: Urine Test
Purpose: To detect signs of infection, such as white blood cells and bacteria, and to rule out other urinary tract pathology.
Expected Findings: Pyuria (white blood cells), bacteriuria (bacteria), proteinuria.
Interpretation: Presence of pyuria and bacteriuria suggests a urinary tract infection, which could be the source of ascending infection to the testicle. Test Name
Urine Culture and Sensitivity
Type: Urine Test
Purpose: To identify specific bacterial pathogens and determine their antibiotic susceptibility.
Expected Findings: Growth of pathogenic bacteria (e.g., E. coli, Neisseria gonorrhoeae, Chlamydia trachomatis).
Interpretation: Guides appropriate antibiotic selection for bacterial orchitis. Test Name
STI Testing (e.g., NAAT for Gonorrhea and Chlamydia)
Type: Swab (urethral/urine) Test
Purpose: To detect the presence of sexually transmitted infections, common causes of bacterial orchitis in sexually active individuals.
Expected Findings: Positive detection of Neisseria gonorrhoeae or *Chlamydia trachomatis

• DNA/RNA.

Scrotal Ultrasound
Purpose: To visualize the testicles and surrounding structures, differentiate orchitis from other scrotal pathologies, assess blood flow, and identify complications.
Typical Findings: Enlarged testicle with heterogeneous echotexture, increased vascularity on Doppler ultrasound, reactive hydrocele, thickened scrotal skin, and possible epididymal abnormalities. In testicular torsion, there is typically absent or diminished blood flow.
Clinical Importance: Essential for diagnosis, especially to rule out testicular torsion, a surgical emergency. It helps assess the severity of inflammation and detect complications like abscess formation.

• Testicular Torsion: Acute, severe unilateral testicular pain. Doppler ultrasound is crucial as it shows absent or markedly reduced blood flow, whereas orchitis demonstrates increased vascularity.
• Epididymitis: Inflammation of the epididymis, often preceding or occurring with orchitis (epididymo-orchitis). Pain and swelling are primarily localized to the epididymis, but the testicle can also be involved.
• Testicular Trauma: History of direct injury to the scrotum. Ultrasound may show hematoma or parenchymal contusion.
• Inguinal Hernia: Palpable bulge in the groin or scrotum, often reducible.
• Testicular Tumor: Usually presents as a painless mass or enlargement of the testicle. Ultrasound may show a solid, hypoechoic lesion.

• Testicular atrophy (shrinkage of the testicle)
• Infertility (reduced sperm count or complete azoospermia)
• Chronic testicular pain
• Testicular abscess
• In rare cases, gangrene requiring orchiectomy
• Hypogonadism (reduced testosterone production)

A. Lifestyle Modifications

• Strict adherence to prescribed antibiotics.


• Complete rest, especially in the acute phase.


• Scrotal support (e.g., athletic supporter) to reduce discomfort and edema.


• Avoidance of strenuous physical activity until symptoms resolve. B. Preventive Measures


• Mumps vaccination.


• Safe sexual practices (condoms) to prevent STIs.


• Prompt treatment of UTIs. C. Medical Treatment

The prognosis for orchitis is generally good with prompt diagnosis and appropriate treatment. Most cases resolve within weeks to months. However, potential long-term complications can significantly impact prognosis, including testicular atrophy, chronic testicular pain, and infertility due to impaired spermatogenesis or hypothalamic-pituitary-gonadal axis dysfunction. The risk of infertility is higher with bilateral orchitis or if complications like testicular atrophy occur.

• Primary Prevention: Ensure complete immunization against mumps. Practice safe sex to prevent STIs. Maintain good hygiene and prompt treatment of UTIs.
• Secondary Prevention: Regular follow-up with healthcare providers if at risk for STIs or UTIs. Promptly seek medical attention for any scrotal pain or swelling.
