Patient's question:
My left testicle is smaller than the right one, but both feel particularly small to me. I don't know how to determine if this is normal.Doctor's answer:
Hello, the individual variation in testicular volume among normal adult males is significant. The testicles on both sides of a normal person are not exactly the same. Statistics show that the right testicle is slightly larger than the left, with an average size of 3.38×2.27×1.71 cm on the right and 3.30×2.37×1.78 cm on the left. Even among individuals of the same age group, there are differences in testicular size. In normal adult males, the volume of the testicles can range from as large as 25 mL to as small as several mL. It is generally considered that testicular volume smaller than 10 mL in adults is classified as microorchidism. It is recommended that in normal individuals, the testicles on both sides may not be equal, but the difference should not be too large. If both testicles fall within the normal size range, it will not affect fertility. However, if the difference is significant, it generally indicates the presence of certain urogenital system diseases, and it is necessary to seek medical attention for early examination and diagnosis.
