The testis or testicles are a part of the male reproductive organs. Also frequently referred to as “balls”, healthy testicles resemble the shape of eggs and are usually located in the scrotum. The testicles are a vital part of the male anatomy for two major reasons; the testicles produce semen, which is necessary for conception, hence the “family jewels”, and they produce testosterone, the main male hormone responsible for many male characteristics. What is the average testicle size? We will cover that and much more in this article.
Does Size Matter? Big Balls vs. Small Eggs
Now, when it comes to the size of the testicle, what is better: big or small? Or does size really matter?
Some men consider testicle size to be a measurement of manliness and masculinity. In fact, many men report feeling more confident in themselves when their testicle size surpasses that average mark. Because of this, some men strive to have larger testicles.
When considering the functionality, the size of the testicle does not matter as much as a healthy “plumbing!” If the testicles are smaller than average but do produce enough healthy semen, and the semen is transferred through a healthy duct system to the penis, then conception should not be a problem. Testicle size becomes important when the gonads cease to grow or undergo pathological shrinkage.
One other important aspect of the size of the testicle is its aesthetics. Some men have smaller than average testicles and are not very happy with their scrotal appearance. Other men just have a bigger than average penis size, which makes the testicles appear small.
Average Testical Size
Testicles are oval in shape and typically weigh about 20g. The average testicle size ranges from 3.6 to 5.5 cm in length and 2.1 to 3.5 cm in width. Keep in mind that one testicle is typically slightly larger than the other. The testicles undergo size variation as we age. While very small during infancy, the testicles typically rapidly grow during puberty and take their ultimate shape and size during adulthood.
Dr. James Tanner was a British pediatrician who established a reference chart for measuring male testicle size. It is known as Tanner stages, and it follows the stages of the body’s development from infancy to adulthood. This chart provides the average testicle size through different stages of life and measures them in volume (ml).
- Childhood – 1 to 3 ml
- Early Puberty – 4 to 6 ml
- Mid Puberty – 8 to 10 ml
- Late Puberty – 14 to 16 ml
- Adulthood – 18 to 25 ml
When Do Testicles Start and Stop Growing?
At birth, the testicles will measure about 1 cubic centimeter and continue to stay this size until around the age of 8. From this point, there will be steady growth until sometime during puberty when they will reach adult size. Puberty is also the point where hair will appear on the scrotum and around genitals.
Is It Normal to Have Two Different Size Testicles?
Naturally, there is a size difference between your testicles. One of them, usually the right one, is always smaller than the other, and one of them is usually always hanging lower than the other.
Can Testicles Shrink?
Age causes testosterone levels to drop, and this could cause a decrease in the size of your testicles, which is known as testicular atrophy. This change typically happens gradually and most men will not even notice it. Your testicles shrinking naturally has no threat to your health.
A decrease in testosterone can cause a reduction in libido and muscle mass, but again, this is a natural part of aging. Certain health issues could cause testicular atrophy, which includes:
- STDs including gonorrhea and syphilis
- Mumps, tuberculosis and certain viral infections of the testicles
- Trauma to the testicles
Testicle size measurement can be done with a measurement tape. By measuring the length, width, and depth of a testicle, you can determine the testicle volume as a good size reference.
An easier way of measurement is by using a so-called “orchidometer.” The orchidometer consists of a series of oval-shaped beads made from plastic or wood that are strung together in the order of increasing size.
Each bead is marked with a number on it, which corresponds to a milliliter (ml) amount. For example, the oval marked as 5 has a volume of 5 ml. If you are curious about the size of your testicles, you can simply visit your doctor/urologist and have the measurement done in the office. Alternatively, you can purchase or print paper size references and use them to determine the size of the testicle.
