Testicular Swelling and Lumps: Causes and Advice - Urology

More Info

---

Testicular swelling and lumps can be concerning symptoms that warrant careful evaluation. The testicles are sensitive organs, and any changes in their size, shape, or consistency can indicate underlying health issues. Based on your description, it seems that you are experiencing intermittent swelling and discomfort in your left testicle, which may be exacerbated by prolonged activity, such as walking.

There are several potential causes for testicular swelling and lumps, including:
1. Epididymitis: This is an inflammation of the epididymis, the tube that carries sperm from the testicle. It can cause swelling, pain, and tenderness, often accompanied by fever or discharge. Epididymitis can be caused by infections, including sexually transmitted infections (STIs).

2. Orchitis: This is an inflammation of the testicle itself, which can occur due to viral or bacterial infections. Mumps virus is a common cause of viral orchitis.

3. Hydrocele: This is a fluid-filled sac around a testicle that can cause swelling. Hydroceles are usually painless and may resolve on their own.

4. Varicocele: This is an enlargement of the veins within the scrotum, often described as feeling like a "bag of worms." Varicoceles can cause discomfort and may affect fertility.

5. Testicular torsion: This is a medical emergency where the spermatic cord becomes twisted, cutting off blood supply to the testicle. It typically presents with sudden, severe pain and swelling and requires immediate medical attention.

6. Tumors: While less common, testicular tumors can present as lumps or swelling. These can be benign or malignant, and any new lump should be evaluated by a healthcare professional.

Given that you have noted a change in the size and shape of your left testicle, it is essential to seek medical attention. A healthcare provider will likely perform a physical examination and may recommend an ultrasound to assess the structure of the testicles and surrounding tissues. This imaging can help differentiate between fluid collections, tumors, and other abnormalities.

Regarding your concern about frequent masturbation, while it is a normal sexual activity, excessive or aggressive manipulation of the testicles can sometimes lead to discomfort or swelling. However, masturbation itself is not typically a direct cause of testicular swelling or lumps. It is essential to maintain a healthy balance and listen to your body. If you notice persistent discomfort or changes, it may be worth discussing your habits with a healthcare provider.

In summary, it is crucial to take your symptoms seriously and consult a healthcare professional for a thorough evaluation. Early diagnosis and treatment can prevent complications and ensure your reproductive health is maintained. Remember, it is always better to err on the side of caution when it comes to changes in your body, especially in sensitive areas like the testicles.
