The testicle is the most important physiological organ of the human body, not only related to male health, but also related to physical health and reproductive health. "It may seem to everyone that the impact of testicular size is not significant, but it is not entirely the case.". So, how do you know the size of the testicles? Let's take a look together!
This method is not limited by conditions, and the results are more accurate, but time-consuming. Use a caliper to measure the length, width, and thickness of the testis, and then calculate the volume of the testis according to the formula.
Testicular volume (cm3)=length diameter (cm) × Width and diameter (cm) × Thickness diameter (cm)
Testicular volume meter
According to the volume calculated in advance, elliptical hard objects resembling testicles in different volumes are made, and they are labeled 1-25 based on their size. During measurement, the testicles are pulled up, the scrotal skin is tightened, and the measuring pieces (i.e., testicular models) are compared one by one beside the testicles. The measured quantum volume that is similar to the testicular size can be considered as the testicular volume. This is a commonly used testicular volume measurement method in the world. The testicular volume (including scrotal skin) of normal adult males in China ranges from 15 to 25 sizes.
This is an earlier method. During measurement, pull down the testicle under test, take warm water (around 25 ℃) and place it in a calibrated container, so that the testicle under test is completely submerged in water. The milliliter increase in water volume after immersion of the testicle is used as the volume of the testicle and is now less commonly used.
It is also reported that the average length, width, and thickness of the left testicle were 3.0, 2.5, and 2.1 (cm) in healthy men aged 23-45 years with a normal reproductive history in China.
The average length, width, and thickness of the right testicle were 4.0, 2.4, and 2.2 (cm), respectively. There was no significant difference in the volume of the left and right testicles between fertile and infertile males. Due to the large differences in testicular volume in normal men, there are also certain differences in testicular volume on both sides of the same individual, so the measured results can only be used as a reference. The determination of testicular development and fertility should be comprehensively analyzed in conjunction with other examination results.
