Q: Testicular Size Differences: When to Seek Medical Advice

Testicular size

Hello Dr.
Lin, I would like to ask you about an issue regarding my testicles.
I feel that my right testicle is slightly larger than the left, and the right testicle also hangs lower than the left (though this difference is only noticeable when the scrotum is relaxed).
Is this considered normal? Are both testicles usually the same size? This condition has been present for quite some time.
I visited a urology clinic about two years ago, and the doctor performed a visual and physical examination, stating that everything was normal.
However, I recently came across reports about testicular cancer symptoms, which mention that one side of the testicle may become enlarged.
I am a bit concerned—if it were testicular cancer, would the testicle noticeably increase in size? Thank you, doctor.

2.

3.
Testicular cancer typically presents as a painless enlargement, and the testicle may feel firm and continue to grow.
Since you have already consulted a urologist, there should not be any issues unless you have noticed a significant increase in the size of one testicle over the past two years, in which case you should return to the urologist for evaluation.
Wishing you peace and happiness.

More Info

When it comes to testicular size differences, it is quite common for one testicle to be slightly larger or hang lower than the other. In fact, most men experience some degree of asymmetry in their testicles. Typically, the left testicle hangs lower than the right, and variations in size can occur due to a variety of factors, including genetics and normal anatomical differences.
In your case, you mentioned that your right testicle appears slightly larger and hangs lower than the left. If a healthcare professional has previously examined you and deemed this to be normal, it is likely that there is no cause for concern. However, it is always wise to remain vigilant about any changes in your body, especially when it comes to areas that can be affected by serious conditions like testicular cancer.

Testicular cancer often presents with symptoms such as a noticeable lump or swelling in the testicle, which may not necessarily be accompanied by pain. In some cases, men may notice a change in the size or shape of one testicle, but this change is usually more pronounced than the slight differences you are describing. If the size difference is significant or if you notice any other symptoms such as pain, discomfort, or changes in the texture of the testicle, it is advisable to seek medical attention promptly.

It is also important to conduct regular self-examinations of your testicles. This involves gently rolling each testicle between your fingers to feel for any lumps, swelling, or changes in texture. The best time to perform this self-exam is after a warm shower when the scrotum is relaxed. If you notice any new lumps, swelling, or other changes, do not hesitate to consult a healthcare provider.

In summary, slight differences in testicular size and position are generally normal and can be attributed to anatomical variations. However, if you have concerns about testicular cancer or notice any significant changes, it is always best to consult a healthcare professional for a thorough examination and peace of mind. Regular check-ups and self-examinations are key components of maintaining reproductive health and catching potential issues early.
