Is it normal for the testicular sac to be full?

Do you know? The testicles on both sides of a man are not "balanced", but the left is lower and the right is higher, the left is larger and the right is smaller. Even the connoisseur Ma Weidu and the famous professor have filed a lawsuit over this. It turns out that in the fetal stage, both sides of a man's testicles are inside the abdomen. With the growth and development, the testicles gradually descend, and the left testicle usually descends into the scrotum first. The poor right testicle, although it tries its best to catch up, falls at the starting line, and its position is higher than the left testicle. As the saying goes, "one step can't keep up, one step can't keep up". So are normal testicle bags round?

The left side of a man's testicle is lower than the right side. This is the case for all men.

Are the men's pair of products really different? The answer is undoubtedly yes.

If you search "male testicles" and "height and low" on the web, you will find that many of your friends are deceived by the fact that "when the scrotum is loose, the two male testicles are not on the same level." Andrologists say that the vast majority of male testicles are not only different in height, but also in size!

Although the two male testicles look similar in size, the net weight of these two smooth oval organs is different. The average weight of the left male testicle of an adult male is 10.20 grams; while the right male testicle is relatively heavier, with an average weight of 10.70 grams. Does the heavier one have a more hanging feeling and is located lower? No, in general, the lighter left male testicle is located slightly lower, while the right one is slightly higher, usually 1 cm lower than the right. If you don't believe it, you can look at the famous statue "David". From the back, you can clearly see that Peter's left testicle is low and the right testicle is high; in addition, the two testicles are not hanging parallel, but a little "inward".

Of course, you can also look at your own or your boyfriend's in the mirror, even a few months old baby is like this. It really makes people sigh at the wonder of nature!

Right male testicle "can't keep up with the pace, can't keep up with the pace"

The condition of the left testicle being lower than the right may have started when the baby was in the mother's womb. The testicles spend most of their embryonic development in the abdomen. As the baby grows and develops, the testicles will descend, and will not descend to the scrotum until 30 weeks into embryonic development. This characteristic is crucial for producing healthy sperm. Humans are warm-blooded animals, but high-quality sperm can only be produced in an environment that is less than 2°C above human body temperature. In other words, the human scrotum is a sac separated from the body that controls the growth temperature of sperm inside.

Logically, the testicles on both sides should descend at the same speed, but in fact, this is not the case. For some reason, the right testicle descends slightly later than the left testicle. The left testicle usually descends into the scrotum first, and the poor right testicle, although it tries its best to catch up, still fails to reach the destination on time due to the delay in the race. Even if the right testicle finally reaches the scrotum on time with all its strength, it still cannot sink to the bottom of the scrotum like the left testicle. It is located higher than the left testicle and hangs in the scrotum slowly, which is what is called "can't keep up with one step, can't keep up with every step". Therefore, from a visual point of view, the two testicles are not at the same level, and the right testicle is higher than the left testicle.

There is also a situation where the right male testicle is not sure whether it is tired or too tired during the descending process. In short, it stops on the road and does not leave. Some young mothers will inadvertently find that they cannot touch or only touch one testicle in the child's scrotum when bathing their babies. The mother will often be frightened and sweat all over, and be at a loss. This is the so-called cryptorchidism. About 3% of full-term male babies suffer from cryptorchidism, of which about 70% of cryptorchidism will naturally descend into the scrotum within 3 months after birth. When they reach 1 year old, about 1% of boys will still have the problem of cryptorchidism. The vast majority of cases of cryptorchidism are unilateral, with the right side being more likely to be affected than the left.

If one side of the male testicle suddenly enlarges, you should go to the hospital for a physical examination.

Some people may ask, why are the heights and weights of men's testicles different? Is it an inevitable trend of life evolution? Does it have some unique practical significance?

Some people have proposed a basic theory: when the testicles are squeezed by the legs or collided with external forces, they are less likely to be injured if they are up and down. If they are symmetrical and parallel, they are more likely to be squeezed together and cause injuries. But theories are theories after all, and there is no scientific evidence to prove it. Some people consulted a doctoral student at the School of Medicine of Peking University about this problem, and he said, "Ask the God"...

It can only be said that, just as a person's left hand and right hand are different sizes, the upper and lower legs are different lengths, and the upper and lower shoulders are different heights, it is really difficult to grow a completely symmetrical microorganism.

In general, the testicles of ordinary people are indeed different in height and size, but the difference is generally not big. If the testicles of both sides used to be similar in size, and one side of the testicle suddenly enlarged recently, you should go to the hospital for a physical examination immediately. If the enlargement of one side of the testicle is accompanied by fever and local pain, it may be epididymitis or orchitis. If the enlargement of the testicle is not accompanied by any symptoms, you should consider the possibility of testicular tumors and check it out immediately without any hesitation.
