Testicular issues


Hello doctor, I noticed a small lump on my left testicle while self-examining, about the size of a corn kernel, and sometimes I experience intermittent pain.
This has been ongoing for a few weeks.
Could this be a symptom of an epididymal cyst? Is the situation serious?

Niming, 20~29 year old female. Ask Date: 2017/01/11

Dr. Du Shixi reply Urology


Hello: Most cases are not serious, but if there are cramping pains, you should consult a physician.
If there is an increase in size, it is also important to seek medical evaluation at a hospital.
Thank you for your inquiry.

More Info


Epididymal cysts, also known as spermatic cysts or epididymal masses, are fluid-filled sacs that develop in the epididymis, which is the coiled tube located at the back of the testicle responsible for storing and maturing sperm. These cysts are generally benign and often asymptomatic, but they can sometimes cause discomfort or pain, particularly if they grow larger or become inflamed.

Based on your description of a small lump on the left testicle, approximately the size of a corn kernel, accompanied by intermittent pain over the course of several weeks, it is possible that you are experiencing symptoms related to an epididymal cyst. These cysts can vary in size and may feel like a soft, movable lump. The pain you are experiencing could be due to irritation or pressure on surrounding tissues, especially if the cyst is pressing against nerves or other structures in the scrotum.

While epididymal cysts are typically not serious and do not require treatment unless they cause significant discomfort or complications, it is essential to have any new or unusual lumps in the testicular area evaluated by a healthcare professional. A thorough examination, which may include a physical examination and possibly an ultrasound, can help confirm the diagnosis and rule out other potential conditions, such as testicular torsion, varicocele, or even testicular cancer, which may present with similar symptoms.

In most cases, if the cyst is confirmed and is not causing severe symptoms, the recommended approach may be simply to monitor it over time. However, if the cyst becomes painful, grows in size, or if there are any concerns about the nature of the lump, surgical intervention may be considered to remove the cyst.

It is also worth noting that while epididymal cysts are common, other conditions affecting the testicles can present with similar symptoms. For instance, epididymitis (inflammation of the epididymis) can cause pain and swelling and may be associated with infection. Testicular torsion, a medical emergency, can also present with sudden severe pain and requires immediate attention.

In conclusion, while your symptoms may suggest an epididymal cyst, it is crucial to consult with a healthcare provider for an accurate diagnosis and appropriate management. Early evaluation can help alleviate concerns and ensure that any necessary treatment is provided promptly. If you experience any sudden changes in symptoms, such as increased pain, swelling, or fever, seek medical attention immediately.
