Testicular Atrophy and Varicocele: When to Consider Surgery? - Urology

Share to:

One side is larger while the other side is smaller?


Hello Doctor, I would like to inquire about my condition.
I have been diagnosed with varicocele since childhood, and I had an examination around middle school.
Recently, I feel that the left side has become more severe, and the left testicle is smaller than the right one.
I would like to know if surgery is recommended immediately, or if it can wait for about six months since I am an athlete and may have competitions coming up.
Additionally, in the case of unilateral testicular atrophy, does the atrophied testicle lose its function? Could this lead to infertility, or is it more likely to require both sides to be affected?

Hello: There is a possibility of recurrence after surgery, and there is no chance of the testicles increasing in size post-surgery (many people have the issue of one testicle being larger than the other).
There may also be issues with wound pain after the surgery.
It is recommended that you visit a urology department at a large hospital for an examination and to clarify whether surgery is necessary and the timing of the surgery.
Thank you for your inquiry.

Testicular atrophy and varicocele are two interrelated conditions that can significantly impact male reproductive health. Understanding when to consider surgical intervention is crucial, especially for someone like you who is an athlete and may have specific performance and health considerations.

Understanding Varicocele and Testicular Atrophy
A varicocele is an enlargement of the veins within the scrotum, similar to varicose veins that can occur in the legs. It is often associated with testicular atrophy, which is a reduction in the size of the testicles. This condition can lead to decreased testosterone production and impaired fertility. The left testicle is more commonly affected due to anatomical reasons, as the left testicular vein drains into the left renal vein, which can create a higher pressure environment.

When to Consider Surgery
Surgical intervention for varicocele is typically recommended when there are symptoms such as pain, discomfort, or when there is evidence of testicular atrophy or infertility. In your case, since you have noticed that your left testicle is smaller than the right and you have a history of varicocele, it may be prudent to consider surgery sooner rather than later, especially if you are experiencing discomfort or if there is a concern about fertility.

1. Timing of Surgery: If you are preparing for an upcoming competition, it may be wise to wait until after the event to undergo surgery, provided that your symptoms are manageable and not significantly affecting your performance. However, if you are experiencing pain or if the atrophy is progressive, it may be advisable to consult with a urologist to discuss the potential benefits of surgery before your competition.

2. Impact of Testicular Atrophy on Function: Testicular atrophy can lead to a decrease in sperm production and testosterone levels. If only one testicle is affected, the other testicle may compensate to some extent, but this is not guaranteed. If the atrophied testicle is significantly reduced in size, it may have lost some or all of its function, potentially impacting fertility. However, it is not necessary for both testicles to be affected for infertility to occur; unilateral atrophy can still lead to reduced fertility.

3. Fertility Considerations: If you are concerned about fertility, it is essential to have a semen analysis performed. This test can provide insight into your sperm count and motility, helping to determine if the varicocele is affecting your fertility. If you are planning to start a family in the near future, addressing the varicocele may be beneficial.

4. Monitoring and Follow-Up: If you decide to wait for surgery, regular monitoring of the condition is important. Keep track of any changes in size, pain levels, or other symptoms. If you notice any worsening of your condition, it would be advisable to seek medical advice sooner.

5. Consultation with a Specialist: Ultimately, the decision to proceed with surgery should be made in consultation with a urologist who specializes in male reproductive health. They can provide a thorough evaluation and discuss the risks and benefits of surgery, as well as alternative treatments if surgery is not immediately necessary.

In summary, while it may be possible to wait for surgery if your symptoms are not severe and you have an upcoming competition, it is crucial to monitor your condition closely. Testicular atrophy can impact fertility, and addressing varicocele may help preserve testicular function. Consulting with a urologist will provide you with tailored advice based on your specific situation and health goals.
