Testicular swelling is a surprisingly common concern and often causes anxiety and prompts questions about potential underlying health issues.
Swollen testicles can indicate something as minor as a fluid buildup or something more serious, like testicular torsion, testicular cancer, or an infection. Understanding what causes a swollen testicle is crucial for seeking the right treatment and protecting your reproductive and overall health.
Common Causes of a Swollen Testicle
Testicular swelling can stem from a wide range of issues. Some causes are acute and painful, while others may develop gradually and remain unnoticed until the swelling becomes visible.
Testicular Torsion
One of the most urgent causes of a swollen testicle is testicular torsion. This condition occurs when the spermatic cord twists, cutting off blood flow to the testicle. A torsed testicle swells rapidly and is usually accompanied by intense pain. The affected testicle may appear higher than the other and feel firmer to the touch.
If you're experiencing sudden testicular swelling with severe pain, seek immediate medical attention. Delay in treatment can lead to permanent damage.
Infections and STDs
Infections are a leading cause of swollen testicles and scrotal inflammation. Conditions like epididymitis (inflammation of the epididymis) or orchitis (inflammation of the testicle itself) often present as swelling and may include redness, warmth, and tenderness. These can be caused by:
Bacterial infections, including urinary tract infections (UTIs)
Sexually transmitted diseases (STDs) such as chlamydia or gonorrhea
Men experiencing a painful, swollen right testicle, painful urination, or fever should be evaluated for infection immediately.
Spermatocele and Hydrocele
A spermatocele is a fluid-filled sac that develops in the epididymis and can cause an enlarged testicle without pain. Similarly, a hydrocele is a fluid accumulation in the scrotum that results in a swollen scrotum. These conditions are generally benign but may require surgical removal if they grow or cause discomfort.
Testicular Cancer
Testicular cancer often appears as a painless lump or swelling in one testicle and can easily go undetected without routine self-exams. While it's most commonly diagnosed in younger men, it can develop at any age.
While not all testicular swelling is cancerous, any persistent lump or enlargement should be examined by a urologist.
When Should You Be Concerned About a Swollen Testicle?
You should see a urologist immediately if:
The swelling comes on suddenly
It is accompanied by severe pain
You have fever, chills, or urinary symptoms
You notice a lump that doesn't go away
There's redness or warmth in the scrotum
The pain radiates into the abdomen or groin
Early diagnosis can be the difference between a treatable infection and long-term reproductive damage.
