Does the left testicle being smaller than the right affect sexual life? How to solve it?

Patient's question:

Left testis smaller, right testis larger

Doctor's answer:

The testicles of a normal person are not the same size on both sides, but the difference is not significant. If both testicles were symmetrical in the past and one is now noticeably larger, it should be a cause for concern. If the testicle enlargement is accompanied by fever and local pain, it may be epididymitis or orchitis. If the testicle enlargement occurs without any other symptoms, the possibility of a testicular tumor is higher, and it is important to seek further examination in the urology department promptly. Do not be negligent.
