Testicular swelling can be a worrying symptom, often indicating an underlying medical condition. It’s crucial to understand the potential causes, recognize associated symptoms, and seek appropriate medical care. Here, we explore the various causes of testicular swelling, methods of diagnosis, and treatment options to help maintain optimal testicular health.

Common Causes of Testicular Swelling
1. Epididymitis

Epididymitis is the inflammation of the epididymis, the coiled tube at the back of the testicle that stores and carries sperm. It is commonly caused by bacterial infections, including sexually transmitted infections (STIs) like chlamydia and gonorrhea.

2. Orchitis

Orchitis is the inflammation of one or both testicles, often caused by viral or bacterial infections. Mumps is a well-known viral cause of orchitis, particularly in adolescents and adults.

3. Hydrocele

A hydrocele occurs when fluid accumulates in the sac surrounding the testicle, leading to swelling. It is often painless and can be present at birth or develop later in life due to injury or inflammation.

4. Varicocele

A varicocele is an enlargement of the veins within the scrotum, similar to varicose veins in the legs. It can cause swelling and discomfort, often becoming more noticeable after physical activity.

5. Testicular Torsion

Testicular torsion is a medical emergency that occurs when the spermatic cord twists, cutting off the blood supply to the testicle. This causes sudden, severe pain and swelling and requires immediate surgical intervention.

6. Inguinal Hernia

An inguinal hernia occurs when a portion of the intestine protrudes through a weak spot in the abdominal muscles, sometimes extending into the scrotum and causing swelling and discomfort.

7. Testicular Cancer

Although less common, testicular cancer can present as a lump or swelling in the testicle. Early detection and treatment are crucial for a favorable outcome.

Understanding the causes and seeking prompt medical attention can ensure effective treatment and improve outcomes.
