Is One Testicle Larger Than the Other a Cause for Concern? - Urology

More Info

---

It is quite common for one testicle to be larger than the other, and in most cases, this is completely normal and not a cause for concern. The human body is asymmetrical, and this asymmetry extends to the testicles as well. Typically, the left testicle hangs lower than the right, and size differences can vary from person to person. However, there are certain situations where a noticeable size difference could indicate an underlying issue that may require medical attention.

One of the most common reasons for a significant difference in testicle size is a condition known as testicular torsion, which occurs when the spermatic cord becomes twisted, cutting off the blood supply to the testicle. This is a medical emergency and requires immediate attention. Symptoms of testicular torsion include sudden, severe pain in the scrotum, swelling, and sometimes nausea or vomiting. If you experience these symptoms, seek medical help right away.

Another potential concern is the presence of a hydrocele, which is a fluid-filled sac surrounding a testicle that can cause swelling. Hydroceles are usually painless and may not require treatment unless they become uncomfortable or large. In some cases, a varicocele, which is an enlargement of the veins within the scrotum, can also lead to size differences. Varicoceles can sometimes affect fertility and may require treatment if they cause pain or discomfort.

Infections or inflammation, such as epididymitis or orchitis, can also lead to swelling or changes in size. These conditions are often accompanied by other symptoms, such as pain, redness, or fever. If you notice any of these symptoms, it is important to consult a healthcare provider.

If you have noticed a change in size or if one testicle has become significantly larger than the other, it is advisable to see a healthcare professional for an evaluation. They may perform a physical examination and possibly an ultrasound to determine the cause of the size difference. Early detection and treatment of any underlying issues are crucial for maintaining reproductive health.

In summary, while it is normal for one testicle to be larger than the other, any sudden changes in size, accompanied by pain or other symptoms, should be evaluated by a healthcare provider. Regular self-examinations can help you become familiar with your body and detect any changes early on. If you have any concerns about your testicular health, do not hesitate to reach out to a medical professional for guidance and support.
