Testicular issues


Hello, doctor.
I have a question.
When I touch my left testicle, it feels like there is an epididymis, but when I touch the right one, it seems like there is no epididymis, just a thin layer.
What could be the issue? Do my testicles still have function? Is there a chance for recovery?

Hello! Generally, both sides should have epididymis (the term you referred to as "副睪" is the same).
Sometimes it may feel less prominent.
As for whether your testicles are functioning, I believe the answer is affirmative.
However, if you have concerns, feel free to visit the clinic, where we can arrange for an ultrasound examination and semen analysis.

When it comes to concerns regarding the epididymis and testicular health, it is essential to understand the anatomy and function of these structures. The epididymis is a coiled tube located at the back of each testis, responsible for storing and maturing sperm. It is normal for individuals to feel a difference in the texture or size of the epididymis on either side, as anatomical variations can occur. However, any significant changes or discomfort should be evaluated by a healthcare professional.

In your case, feeling a prominent epididymis on the left side and a thinner or less defined structure on the right could indicate several possibilities. One common condition is epididymitis, which is inflammation of the epididymis, often caused by infection. This can lead to swelling, tenderness, and changes in the texture of the epididymis. If the right side feels different, it could also be a sign of a previous infection or a developmental variation.

Another possibility is that you may be experiencing a condition known as testicular torsion, where the spermatic cord becomes twisted, cutting off blood supply to the testis. This is a medical emergency and requires immediate attention. Symptoms typically include severe pain, swelling, and sometimes nausea. If you are not experiencing acute pain but have noticed a change in the texture or feel of your testis, it may not be an emergency, but it still warrants further investigation.

Regarding the functionality of your testicles, if there is no significant pain, swelling, or other alarming symptoms, it is likely that the testicular function remains intact. The testicles produce sperm and testosterone, and unless there is a significant underlying issue, such as a severe infection or torsion, the function should not be compromised. However, if there is a concern about fertility or hormonal levels, a healthcare provider may recommend a semen analysis or hormone testing.

Recovery from any issues related to the epididymis or testicles largely depends on the underlying cause. If it is an infection, appropriate antibiotic treatment can lead to a full recovery. If there are structural issues or concerns about blood flow, further evaluation may be necessary, which could include imaging studies like an ultrasound to assess blood flow and the anatomy of the testicles and epididymis.

In summary, while variations in the feel of the epididymis are common, any significant changes, discomfort, or concerns about testicular function should be discussed with a healthcare provider. They can perform a thorough examination, possibly including imaging studies, to determine the cause of your symptoms and recommend appropriate treatment. Early intervention is key to ensuring optimal reproductive health and addressing any potential issues before they become more serious.
