Testicular Pain and Asymmetry: Common Urology Concerns - Urology

Bird egg problem


Hello, Doctor...
I would like to ask a question.

1.
Is it normal for the left and right sides of the scrotum to be the same size?
2.
I have noticed that when I touch a specific area on the left side of my scrotum, it hurts, and the pain radiates from the inside to the outside.
Usually, there are no symptoms, and the pain only occurs when I touch it, even though I apply only light pressure.
This has been happening for about 3 to 5 years.
The right side of my scrotum does not hurt when I touch it.
I have also observed that the left side's spermatic cord is thicker and wider compared to the right side.
The pain seems to be located at the junction of the left scrotum and the spermatic cord, and pressing there causes a sharp, nerve-like pain.
What could this symptom indicate?
3.
Additionally, I have been experiencing frequent urination and a sensation of incomplete bladder emptying, which has also been ongoing for over 3 years.

Hello: The difference in size between the left and right scrotum, along with left scrotal pain, raises the suspicion of conditions such as epididymitis or varicocele.
A thorough physical examination or scrotal ultrasound is necessary.
Please consult Dr.
Chen Hsiu-Yi in the Urology Department for further evaluation.

When it comes to testicular pain and asymmetry, it is essential to understand the anatomy and physiology of the male reproductive system. The testicles, or testes, are typically not perfectly symmetrical; it is common for one testicle to hang lower than the other, and slight size differences can occur. However, persistent pain or discomfort in one testicle, especially if it has been present for several years, warrants further investigation.

From your description, it seems that you are experiencing localized pain in the left testicle, particularly around the area where the testicle connects to the spermatic cord. This could indicate several potential issues. One possibility is a condition known as epididymitis, which is inflammation of the epididymis (the tube that stores and carries sperm). This condition can cause pain and swelling in the affected testicle and may be associated with urinary symptoms, such as the feeling of incomplete bladder emptying.

Another potential cause of your symptoms could be a varicocele, which is an enlargement of the veins within the scrotum. Varicoceles can lead to a feeling of heaviness or discomfort in the affected testicle, and they are more commonly found on the left side due to anatomical differences in venous drainage. The sensation of pain that radiates from the inside to the outside could also suggest nerve involvement, possibly due to irritation or compression in the area.

Additionally, you mentioned experiencing increased urinary frequency and a sensation of incomplete urination. This could be related to a urinary tract infection (UTI), bladder irritation, or even prostate issues, especially if you are in the age range where benign prostatic hyperplasia (BPH) can start to occur. It is important to note that urinary symptoms can sometimes be linked to testicular pain, as the nerves that supply these areas are interconnected.

Given that you have had these symptoms for several years, it is crucial to seek a thorough evaluation from a urologist. They may perform a physical examination, ultrasound imaging of the scrotum, and possibly urine tests to rule out infections or other underlying conditions. It is also important to discuss any changes in your urinary habits and the nature of your pain in detail, as this information can help guide the diagnosis.

In summary, while some asymmetry in the testicles is normal, persistent pain, especially if localized and associated with other symptoms like urinary frequency, should not be ignored. A comprehensive evaluation by a healthcare professional is essential to determine the underlying cause and appropriate treatment. Early diagnosis and management can help alleviate symptoms and prevent potential complications.
