What is the most accurate way to calculate testicle size?

Men's attention to their genitals is usually focused on the penis, while the size of the testicles is ignored. In fact, most of the men who are most concerned about the size of their testicles are those who are unable to conceive after marriage. Once male infertility is diagnosed, it is necessary to understand the impact of testicle size on fertility! So, how to calculate the testicle size in a standard way?

1. Caliper measurement method

This method is not limited by conditions and the results are more accurate, but it takes more time. When measuring, use a caliper to measure the length, width, and thickness of the testicle, and then calculate the volume of the testicle according to the formula.

Testicular volume (ml) = length (cm) × width (cm) × thickness (cm) × Л/6

2. Testicular model comparison method

It is also called the quantum comparison method. According to the pre-calculated volume, oval hard objects of different volumes and shaped like testicles are made and numbered from 1 to 25 according to size. When measuring, the testicle is pulled up, the scrotal skin is tightened, and the quantum (i.e., testicular model, which can be purchased in the medical device market) is placed next to the testicle for comparison. The volume of the quantum that is similar to the testicle can be regarded as the testicular volume.

3. Drainage measurement method

This is an earlier method. When measuring, pull down the testis to be measured, take warm water and put it in a container with a scale, so that the pulled-down testis is completely submerged in the water. The number of milliliters of water that increases after the testis is submerged is taken as the volume of the testis. Because it is inconvenient to use in clinical practice, this method is rarely used now.

It is worth pointing out that the testicular volume of normal men varies greatly, and the volume of the two sides of the testicles of the same individual also varies to a certain extent, so the measured results can only be used as a reference. The judgment of testicular development and fertility must be combined with the results of other examinations, and a comprehensive analysis can be made before a conclusion can be drawn.

According to reports, the testicular volume of adult males in my country (measured by caliper) is: 19-23 years old, the left side is (13.1±3.6) ml, the right side is (13.6±4.2) ml, 24-45 years old, the left side is (13.6±4.2) ml, the right side is (14.4±4.5) ml. The above is for reference only.

Generally speaking, as long as the testicle size is within the normal range and the endocrine function is normal, it will not affect sexual life. Clinical investigations have found that it is very rare for testicles to be smaller than size 8 to affect sexual function. Therefore, generally, you should not worry too much about your testicles.
