Why are the two testicles different in size?

We all know that the distinction of human gender can be determined from our genitals. The uterus is a female-specific organ, while the testicles are male-specific reproductive organs. They can provide a large number of sperm and eggs to combine and breed a new life. From a physiological structure point of view, men have two testicles. Under normal circumstances, the difference between the two is not big, but some people have different sizes. What is going on?

An expert said: Two testicles of an adult weigh about 20 to 30 grams. I saw a set of data, the average length of the left and right testicles is 3.30 to 3.38 cm, the width is 2.27 to 2.37 cm, and the average thickness is 1.71 to 1.78 cm, which means that the length, width and thickness of the testicles are about 3 cm x 2 cm x 1 cm, which is about 3, 2, 1. With the increase of age, especially in old age, the volume of the testicles will gradually shrink, and the volume of the testicles will increase significantly during puberty. There are four types of cells in the testicles, including nerve cells, spermatogonia, spermatocytes and sperm cells.

There is a big difference between spermatogonia in the testicles and oocytes in the female ovaries. Male spermatogonia can be continuously produced, so male reproductive function can be maintained. Even men in their 70s and 80s can still have the next generation. Women are different. After giving birth, the oocytes in the ovaries of women are fixed. They will decrease rather than increase throughout their lives. When the reserve in the ovaries reaches about 50 years old, the ovarian function will gradually decline, menstruation will stop, and menopause will begin. There is a significant difference in the duration of male and female fertility. The size of the testicles is not important. What is important is that the cells inside them are vigorous and energetic, especially during puberty, when there is continuous vitality. So don't worry about whether it is big or small. Its function is very important.

What if they are obviously different in size? Doctors tell male friends that male testicles are not necessarily the same size, but if there is a big difference between the two, the impact of diseases should be considered. Common diseases include urinary tract infection, varicocele, and traumatic impact, which can cause testicular abnormalities.

Male testicles are very fragile and can be easily disturbed by some external factors. Let me explain it to you from the outside to the inside.

Traumatic blow

Traumatic collision is one of the reasons for testicles to be of different sizes. When the testicles are hit accidentally, the patient may feel severe pain at the time, but after a while, the pain will pass. If the patient's testicles are hit severely, bruising will occur, which is also the reason for testicles to be of different sizes.

Urinary tract infection

There are many types of urinary tract infections, such as prostatitis, epididymitis, and vas deferens inflammation. When these reproductive tissues close to the testicles become inflamed, they can infect the testicles and cause inflammation. When tissue cells become inflamed and congested, they will swell. The severity of the infection varies, and the enlargement of the testicles also varies.

Varicose vein

Varicose vein is also one of the reasons for testicles of different sizes. The spermatic vein is connected to the blood vessels of the testicular tissue. If the blood vessels here are bent or tortuous, the testicle on this side will definitely be affected, so the problem of testicles of different sizes will arise.

Regarding the above expert analysis of the possible situations of two testicles of different sizes, we already know that if the size difference is not very large, there is generally no problem. Only when the size difference of the testicles is too large, it is an abnormal situation. Here we still recommend that you go to the hospital for diagnosis and treatment as soon as possible if you encounter abnormal situations.
