The epididymis is a small, coiled tube at the back of each testicle. Its main job is to store, mature, and transport sperm. When harmful bacteria or other infectious agents invade this tube, it causes an epididymis infection, also known as epididymitis. This condition can lead to pain, swelling, and discomfort in the scrotum. If left untreated, an epididymis infection can worsen, spread, or cause complications like infertility or chronic pain. Recognizing the causes and symptoms early helps you get timely treatment.
Structure of the Epididymis
Anatomy Overview
- The epididymis is a single, highly coiled tube. If you stretched it out, it could reach almost 20 feet (6 meters) in length.
- It is divided into three main parts:
- Head (Caput): This is where sperm enters from the testicle.
- Body (Corpus): This is the longest section where sperm matures.
- Tail (Cauda): This is connected to the vas deferens, the duct that carries sperm toward the urethra.
Blood Supply
- Testicular artery: Supplies oxygen-rich blood to the testis and epididymis.
- Pampiniform plexus of veins: Drains deoxygenated blood away and helps regulate the temperature of the testicles.
Nerve Supply
- Sympathetic nerves originate from the lower thoracic and upper lumbar segments, helping to regulate blood vessel constriction and other involuntary functions.
- Parasympathetic nerves help with relaxing certain areas and can influence blood flow.
- Genitofemoral nerve can carry sensory signals from the scrotum area.
Key Functions
- Sperm Transport: Moves sperm cells from the testes to the vas deferens.
- Sperm Maturation: Sperm learns to swim and fertilize an egg during its journey through the epididymis.
- Sperm Storage: Sperm is briefly stored in the tail of the epididymis before ejaculation.
Pathophysiology of Epididymis Infection
Pathophysiology refers to the processes happening in your body during an illness. In an epididymis infection:
- Bacteria, viruses, or fungi enter through the urethra (the tube that carries urine out of the body) or the prostate, eventually making their way to the epididymis.
- The immune system responds with inflammation. Blood flow increases in the area, causing redness, warmth, and swelling.
- This inflammation leads to pain, often felt in the scrotum, testicle, or lower abdomen.
- If not treated promptly, the infection can cause scarring in the epididymis, potentially leading to reduced fertility.
Types of Epididymis Infection
- Acute Epididymitis: Develops suddenly, often with severe pain and noticeable swelling.
- Chronic Epididymitis: Lasts longer than six weeks, with symptoms that can come and go.
- Infectious Epididymitis: Caused by bacteria (e.g., sexually transmitted infections like Chlamydia trachomatis or gonorrhea) or other pathogens.
- Non-Infectious Epididymitis: Triggered by irritation, chemical exposure (e.g., backflow of urine), or trauma rather than a direct infection.
- Epididymo-orchitis: When the infection spreads to both the epididymis and the testicle (orchitis).
Common Causes of Epididymis Infection
- Chlamydia (a common STI).
- Gonorrhea (another frequent STI).
- E. coli (often seen in urinary tract infections).
- Mycoplasma genitalium (less common, but possible).
- Trichomonas vaginalis (a parasitic STI).
- Urinary tract infections that spread.
- Prostate infections (prostatitis) spreading to the epididymis.
- Reflux of urine into the epididymis (chemical irritation).
- Recent urinary tract procedures (catheterization or surgeries).
- HIV infection (weakened immunity leads to opportunistic infections).
- Tuberculosis (rare in developed countries, but possible in some regions).
- Virus-related inflammation (less common).
- Fungal infections (in immunocompromised patients).
- Unprotected sexual intercourse leading to STI transmission.
- Multiple sexual partners increasing infection risk.
- Epididymal trauma leading to secondary infection.
- Congenital structural abnormalities of the urinary tract.
- Chronic indwelling catheters or stents.
- Recent vasectomy, causing occasional inflammation.
- Poor hygiene practices that raise the risk of bacterial spread.
Notable Symptoms and Signs
- Pain in the scrotum, varying from mild to severe.
- Swelling or enlargement of the scrotum or testicles.
- Redness and warmth in the scrotal area.
- Tenderness in the testicles or along the epididymis.

Diagnostic Tests and Examinations
Healthcare providers typically use several methods to confirm an epididymis infection and rule out other conditions:
- Medical History and Symptom Review
- Physical Examination (checking for swelling, tenderness).
- Urinalysis (testing for infection or blood).
- Urine Culture (growing bacteria to identify them).
- Sexually Transmitted Infection (STI) Tests (e.g., swab tests for chlamydia, gonorrhea).
- Complete Blood Count (CBC) (to look for signs of infection).
- CRP (C-reactive protein) and ESR (Erythrocyte Sedimentation Rate) to assess inflammation.
- Scrotal Ultrasound (checks blood flow and structure, often with Doppler imaging).
- Testicular Scan (rarely used but can confirm blood supply).
- MRI of the Scrotum (in complicated or unclear cases).
- Transrectal Ultrasound (TRUS) if a prostate issue is suspected.
- Digital Rectal Exam (to evaluate the prostate gland).
- Pelvic Ultrasound (to look for urinary tract abnormalities).
- Gram Stain of urethral swab discharge (especially for gonorrhea).
- NAAT (Nucleic Acid Amplification Test) for chlamydia and gonorrhea.
- Seminal Fluid Analysis (rare, but can show infection markers).
- TB Screening Tests (if tuberculosis is suspected).
- Fungal Culture (if fungal infection is suspected).
- HIV Test (if indicated by risk factors).
- Urodynamic Tests (to assess urine flow and bladder function in complicated cases).
Non-Pharmacological Treatments
These options can help relieve discomfort and speed up recovery alongside or even before drug therapy:
- Rest and Reduced Activity: Stay off your feet to help reduce swelling.
- Scrotal Support or Athletic Supporter: Minimizes motion that can worsen pain.
- Cold Compresses: Apply for 10-15 minutes to ease inflammation.
- Warm Sitz Baths: Alternating with cold packs can sometimes help comfort levels.
- Elevation of the Scrotum: Propping up the scrotum with a folded towel when lying down.
- Stay Hydrated: Water helps flush bacteria out.
- Avoid Straining: Try not to lift heavy objects or strain during bowel movements.
- Proper Hygiene: Gently washing the genital area to prevent further infection.
- Loose-Fitting Clothing: Reduces friction and pressure on the scrotum.
- Lifestyle Adjustments: Quitting smoking and limiting alcohol to boost overall health.
- Stress Management: Techniques like deep breathing or meditation to help cope with discomfort.
- Apply Warm Compress: Some people find alternating cold and warm packs useful.
- Gentle Massage: If not too painful, light massage around the groin to improve circulation.
- Dietary Modifications: Focus on anti-inflammatory foods (e.g., fruits, veggies).
- Avoiding Irritants: Limit caffeine or spicy foods that can aggravate urinary symptoms.
- Pelvic Floor Exercises: Gentle exercises may improve blood flow and reduce tension.
- Reduced Sexual Activity: Temporary pause or gentle approach until acute pain subsides.
- Biofeedback Therapy: Can help manage chronic pelvic or testicular pain.

- Gentle Walking once severe pain subsides, to improve circulation.
- Ice Packs After Activity to reduce any recurring pain.
- Seek Counseling if dealing with chronic pain and stress.
Pharmacological (Drug) Treatments
Always consult a healthcare provider for guidance on drug selection and dosage. Common categories include:
Antibiotics (first-line treatment if bacterial cause is confirmed):
- Doxycycline
- Ciprofloxacin
- Levofloxacin
- Trimethoprim-sulfamethoxazole (TMP-SMX)
- Azithromycin
Anti-Inflammatory Drugs:
- Ibuprofen
- Naproxen
- Diclofenac
Pain Relievers:
- Acetaminophen (Paracetamol) for mild to moderate pain.
Analgesic Ointments (topical relief, though not very common for epididymis issues).
Alpha-Blockers (e.g., Tamsulosin) in cases with urinary symptoms or prostatitis overlap.
Corticosteroids (rarely used, but helpful in severe inflammatory cases without infection).
Antiviral Medications (for suspected viral causes, e.g., in certain rare infections).
Antifungal Medications (e.g., Fluconazole) if a fungal infection is identified.
Combination Antibiotics for complicated or resistant infections.
Intravenous (IV) Antibiotics for severe or hospitalized cases.
Probiotics in tandem with antibiotics to support gut health (not a direct treatment for epididymis infection, but useful as a complement).
Local Anesthetic Injections (very rarely used for severe pain management).
Muscle Relaxants for associated pelvic floor tension.
Tricyclic Antidepressants (sometimes for chronic pain management).
Opioids (only for short-term severe pain, under careful supervision).
Nonsteroidal Topical Gel (like diclofenac gel) applied carefully if recommended.
Herbal Supplements (e.g., saw palmetto) sometimes discussed for prostate-related urinary issues (caution: not evidence-based for epididymis infection specifically).
Zinc Supplements (potential immune booster, but not a primary treatment).
Vitamin C (to support immune function).
Immunomodulators (very rarely, in chronic or recurring infections under specialist guidance).
Possible Surgical Options
Surgery is not typically the first choice for an epididymis infection. It’s usually reserved for complications or recurrent, severe cases. Below are some procedures:
- Drainage of Abscess: If an abscess (collection of pus) forms.
- Epididymectomy: Removal of the epididymis in severe or chronic, treatment-resistant cases.
- Orchiectomy: Removal of the testicle (very rare and only in extreme, complicated cases).
- Spermatic Cord Block: Injection procedure for chronic pain relief.
- Vasectomy Revision: In rare cases where vasectomy complications lead to chronic epididymitis.
- Microsurgical Epididymal Reversal: If structural issues cause repeated infections (also rare).
- Exploratory Scrotal Surgery: If diagnosis is unclear, to rule out torsion or tumors.
- Prostate Surgery: If an enlarged or infected prostate repeatedly affects the epididymis.
- Ureteral Stent or Catheter Placement: If urinary flow is blocked (indirect link to epididymitis).
- Repair of Anatomical Abnormalities: Correcting congenital or acquired structural issues in the urinary tract.
Ways to Prevent Epididymis Infection
- Practice Safe Sex: Use condoms to reduce the risk of sexually transmitted infections.
- Limit Sexual Partners: Fewer partners generally means lower STI risk.
- Routine STI Screening: Early detection and treatment prevent spread to the epididymis.
- Stay Hydrated: Frequent urination can help clear bacteria from the urinary tract.
- Promptly Treat UTIs: Don’t ignore painful or frequent urination.
- Maintain Good Hygiene: Regular washing and cleaning of the genital area.
- Avoid Unnecessary Catheter Use: Reduces the chance of introducing bacteria.
- Wear Protective Gear: If playing sports, use a protective cup to avoid injury.
- Be Aware of Prostate Health: Regular check-ups if you have a history of prostatitis.
- Strengthen Immunity: Adequate sleep, balanced diet, and stress management.
When to See a Doctor
- If you experience sudden or severe testicular/scrotal pain, seek medical help immediately. This could also be a sign of testicular torsion, a separate emergency.
- High fever and chills indicate a possible serious infection.
- Persistent pain that doesn’t improve with home care after a day or two.
- Discharge, especially if foul-smelling or unusual in color.
- Blood in urine or semen that continues or worsens.
- If non-pharmacological methods (rest, ice packs, etc.) do not bring any relief.
Early intervention is key to preventing complications like infertility, abscess formation, or chronic pain.
Frequently Asked Questions (FAQs)
Q: Can epididymis infection affect fertility?
A: Yes. If it’s severe or untreated, scar tissue can develop, potentially affecting sperm transport.Q: Is epididymis infection always caused by an STI?
A: No. While many cases are sexually transmitted, urinary tract infections, catheter use, or anatomical issues can also cause epididymis infections.Q: Can it spread to the other testicle?
A: It’s possible, though not very common. However, infection can spread from one side to the other or progress to involve the testicle on the same side (epididymo-orchitis).Q: Is it contagious?
A: Epididymitis itself is not “contagious” in a casual sense. But if it’s caused by an STI like chlamydia or gonorrhea, those infections can be transmitted sexually.Q: Can it go away on its own?
A: Mild cases might improve temporarily with rest, but usually medical treatment (especially antibiotics) is needed to fully resolve an infection.Q: How long do I need antibiotics?
A: Typically 1-2 weeks, but some infections require a longer course. Always follow your doctor’s instructions.Q: Can I have sex during treatment?
A: It’s usually best to wait until you’ve completed treatment and are symptom-free. Sexual activity might worsen pain or spread infection if it’s STI-related.Q: Will wearing tight underwear worsen the infection?
A: Tight clothing can increase discomfort and friction. A supportive but not overly tight supporter often helps with pain relief.Q: Can an epididymis infection recur?
A: Yes. Recurrences happen if the underlying cause (like an untreated STI or urinary issue) persists.Q: Is surgery always necessary?
A: No. Surgery is a last resort for complicated or chronic cases that do not respond to medication.Q: Does an epididymis infection cause permanent damage?
A: Most people recover fully, but untreated cases can lead to scarring or chronic pain.Q: Will I need a testicular ultrasound every time?
A: Ultrasound is a common and safe test to rule out other conditions (like torsion). It’s recommended if there’s doubt about the diagnosis.Q: Can I exercise during recovery?
A: Light exercise like walking is okay if it doesn’t increase pain. Avoid high-impact or strenuous workouts until cleared by your doctor.Q: Does age matter?
A: Epididymitis can occur at any age, but it’s more common in younger sexually active men and older men with urinary tract problems.Q: Are there alternative therapies that work?
A: Some find relief with acupuncture or herbal remedies, but these should not replace medical treatments. Always discuss with your healthcare provider.
Conclusion
An epididymis infection can be painful and unsettling, but with early diagnosis and proper care, most individuals recover completely without long-term issues. Knowing its causes and recognizing early signs go a long way in preventing serious complications. By combining medical therapies (like antibiotics) with non-pharmacological measures (like rest, scrotal support, and good hygiene), you can accelerate healing and reduce discomfort.
