Testicular pain is one of the most anxiety-inducing symptoms a man can experience — yet many men delay seeking care out of embarrassment or uncertainty. Understanding the possible causes and recognizing red-flag symptoms can make all the difference in protecting long-term health.

 

What is testicular pain?

Testicular pain (orchialgia) refers to discomfort, aching, or sharp pain in one or both testicles. It may originate directly from the testicle itself, or be referred from another location such as the lower back, groin, or abdomen. Because the testicles share nerve pathways with the kidneys and lower abdomen, pinpointing the exact source can sometimes be challenging without a proper examination.

The pain can range from a mild, dull ache to sudden, severe pain requiring emergency care. Duration also varies — some cases resolve within hours, while others become chronic and last for weeks or months.

 

Common causes of testicular pain

1. Epididymitis

Inflammation of the epididymis — the coiled tube at the back of each testicle — is one of the most frequent causes of testicular pain in adult men. It is often caused by bacterial infection (including sexually transmitted infections such as chlamydia or gonorrhea) or urinary tract bacteria spreading to the epididymis. Symptoms typically develop gradually and include swelling, warmth, and a dull ache that worsens over hours or days.

2. Orchitis

Orchitis is inflammation of the testicle itself. It can occur alongside epididymitis (epididymo-orchitis) or independently, often as a complication of viral infections — most notably the mumps virus. Bacterial causes are also possible. Orchitis may cause significant swelling, redness, and fever in addition to pain.

3. Testicular torsion — a medical emergency

Emergency alert

Testicular torsion occurs when the spermatic cord twists, cutting off blood supply to the testicle. This is a urological emergency. If not treated within 4–6 hours, permanent loss of the testicle may occur. Sudden, severe pain — often with nausea and vomiting — requires an immediate visit to the emergency room.

 

 

4. Varicocele

A varicocele is an enlargement of the veins within the scrotum, similar to varicose veins in the legs. It most commonly affects the left side and may cause a dull, heavy ache that worsens after prolonged standing or physical activity. Varicoceles are also associated with reduced fertility in some men.

5. Hydrocele and spermatocele

A hydrocele is an accumulation of fluid around the testicle, causing scrotal swelling that is usually painless but may produce a sensation of heaviness. A spermatocele is a benign cyst in the epididymis that typically causes mild discomfort or a feeling of fullness. Both are generally benign but should be evaluated to rule out other conditions.

6. Inguinal hernia

When a portion of the intestine pushes through a weak spot in the lower abdominal wall and descends into the scrotum, it can cause testicular or scrotal pain. The pain may be more noticeable during physical activity or when lifting heavy objects.

7. Testicular cancer

Although testicular cancer is relatively rare, it most commonly affects men between the ages of 15 and 35. It often presents as a painless lump or hardness in the testicle, but some men do experience a dull ache or heaviness. Any unexplained lump should be evaluated promptly by a urologist.

8. Referred pain

Pain originating in the kidneys (such as from kidney stones), ureter, or lower back can radiate to the testicles. In these cases, a physical examination of the testicle itself may be entirely normal, which is why a thorough evaluation including imaging is often necessary.

When should you see a doctor immediately?

Do not wait and observe if you experience any of the following:

Sudden, severe pain in one testicle — especially if accompanied by nausea or vomiting

Noticeable lump, hardness, or change in size of the testicle

Scrotal swelling with fever and chills

Pain that persists or worsens over several days

Recent trauma to the groin area followed by pain or swelling

 

Diagnosis and treatment

When you visit a urologist for testicular pain, a typical evaluation includes a physical examination of the scrotum and groin, scrotal ultrasound (the primary imaging tool for scrotal conditions), urinalysis and urine culture, and STI screening where relevant.

Treatment depends entirely on the underlying cause:

Epididymitis / orchitis: antibiotic therapy, rest, scrotal support, anti-inflammatory medication

Testicular torsion: emergency surgical detorsion and fixation (orchiopexy)

Varicocele: observation, or surgical / interventional treatment if causing pain or affecting fertility

Hydrocele / spermatocele: often managed conservatively; surgery only if symptomatic

Testicular cancer: orchiectomy, followed by surveillance, radiation, or chemotherapy depending on stage

Referred pain: treatment of the underlying source (e.g., kidney stone management)

 

Self-examination tips

Monthly testicular self-examination (TSE) is a simple habit that can help detect changes early. The best time to perform it is after a warm shower, when the scrotal skin is relaxed.

Gently roll each testicle between the thumb and fingers

Feel for any lumps, hardness, or changes in size or shape

Note: the epididymis at the back of each testicle is a normal structure — do not confuse it for a lump

If you notice anything unusual, consult a urologist — do not delay out of concern or embarrassment
