What are the symptoms and risks of testicular hernia?

Testicular hernia usually refers to testicular hydrocele. Generally, the main symptoms of testicular hydrocele include difficult urination, local distension pain, scrotal enlargement, abnormal urination, and a sensation of scrotal heaviness. The potential risks of testicular hydrocele include increased risk of testicular malignancy, secondary infection of the scrotum, impaired testicular development, discomfort due to scrotal heaviness, and compromised spermatogenic function. If any discomfort occurs, timely medical consultation and examination are recommended. Detailed analysis is as follows:

I. Symptoms of Testicular Hydrocele

1. Difficult Urination: If there is excessive fluid accumulation, it may pull on the urethra, potentially causing urethral narrowing and resulting in difficult urination.

2. Local Distension Pain: As the fluid accumulates, it may compress surrounding tissues, causing local distension pain. This sensation may worsen as the volume of fluid increases.

3. Scrotal Enlargement: Due to the accumulation of fluid, the scrotum may gradually enlarge, sometimes with a visible mass in the scrotal area.

4. Scrotal Heaviness: Because of the gravitational pull of the accumulated fluid, patients may feel a sensation of scrotal heaviness, particularly when walking or standing.

5. Abnormal Urination: Although testicular hydrocele primarily affects the scrotal area, in rare cases, if the fluid accumulation is very large or located low enough, it may compress the bladder or urethra, leading to symptoms such as difficulty urinating or frequent urination.

II. Risks Associated with Testicular Hydrocele

1. Risk of Testicular Malignancy: While testicular hydrocele does not directly cause testicular cancer, long-term untreated hydrocele carries a certain risk of malignant transformation. The fluid within the hydrocele may exert pressure and irritation on surrounding tissues, and prolonged exposure may lead to DNA damage in local cells, increasing the risk of malignancy.

2. Secondary Infection of the Scrotum: Hydrocele provides a favorable environment for bacterial growth, making infection more likely. Once infection occurs, complications such as orchitis or epididymitis may develop, and in severe cases, surgical removal of the testicle may be necessary.

3. Impaired Testicular Development: In children or adolescents, long-term fluid pressure may affect the growth and development of the testicle, leading to testicular atrophy and underdevelopment. This not only affects fertility but may also cause endocrine dysfunction, impacting the development of male secondary sexual characteristics.

4. Scrotal Discomfort Due to Heaviness: Due to the gravitational pull of the fluid, patients may experience a significant sensation of scrotal heaviness, especially when walking or standing. This discomfort may intensify with increased fluid accumulation, significantly affecting the patient's daily life and work.

5. Impaired Spermatogenic Function: Testicular hydrocele can increase intratesticular pressure, impairing blood circulation and affecting oxygen supply and nutrient delivery to the testicle. Additionally, the accumulated fluid may elevate testicular temperature, which is unfavorable for sperm growth and maturation. Long-term fluid accumulation may also lead to testicular tissue fibrosis, damaging testicular function and reducing sperm quality and quantity, thus affecting the patient's fertility.

Once symptoms appear, prompt medical consultation and professional treatment are essential to minimize potential complications.
