The man’s G-sphere may be influenced by his primitive tissues, forming initially more superiorly near the liver, next to the 2nd to 3rd lumbar vertebrae behind the peritoneum, before developing into a gonad. The male G-sphere spends most of its time in the abdominal cavity during embryonic development. As the male fetus gradually develops, the G-sphere descends. The male G-sphere moves down farther, even leaving the body to fall into the scrotum, and does not descend into the scrotum until after the embryo has reached 30 weeks of development. This feature is quite important for the production of healthy sperm, one reason being that humans are constant temperature animals, but the quantity and quality of sperm must be produced in an environment that is 2 to 3°C below body temperature. In other words, the human scrotum is a bag separate from the body, which can control the growth temperature of the sperm inside. However, this also poses a problem. Since the G-sphere must move a considerable distance to fall into the scrotum, it also makes the spermatic cord wrap around in a large circle. Unfortunately, this causes the wall above the spermatic cord to thin, and as the testicle descends toward the scrotum, the peritoneum that adheres to the surface of the testicle also descends with the testicle and forms an eggplant-shaped pouch, the lower portion of which becomes the intrinsic sphincter of the testicle shortly after birth, while the rest of the pouch atrophies on its own and remains as a fibrous cord. If the upper part of the pouch is not atretic or incompletely atretic, the pouch will be connected to the abdominal cavity, and if a segment of the small intestine pokes out from there and enters the pouch, a hernia will result. It is logical that both testicles should remain the same in terms of the rate of descent, but this is not actually the case. For some reason, the right testicle descends slightly later than the left, and the left testicle is often the first to descend into the scrotum, while the poor right testicle, despite desperately trying to catch up, still fails to reach the end on time until birth because of the delayed start, which directly affects the timely atresia of the upper part of the pouch, and therefore, the right hernia is more common because of this. 60%. In another case, the right testicle is not sure whether it is tired or weary during the descent, in any case, it just stops on the road and does not go. Some young mothers, when bathing their babies, may inadvertently find that they cannot feel or can only feel one testicle in the child’s scrotum. The mother will often break out in a cold sweat and be at a loss for words, which is called cryptorchidism. Cryptorchidism affects about 3% of boys born at full term. About 70% of these cryptorchid will naturally descend into the scrotum within 3 months of birth, and only about 1% of boys will still have cryptorchidism by the time they are 1 year old. Most cases of cryptogram are unilateral, with the right side being more likely to develop than the left. Most of the time, the right testicle, which has struggled to reach the scrotum on time, is still unable to sink to the bottom of the scrotum like the left testicle, which is higher than the left testicle, and hangs in the scrotum with a shudder, as the saying goes: “One step does not follow the other. Therefore, visually, the two testicles are not at the same level, and the right testicle is higher than the left testicle. If you don’t believe me, take a look at yourself when no one is around. In short, both testicles are located in the abdominal cavity in the early embryonic stage, and their position is equivalent to the level of the 2nd to 3rd lumbar vertebrae, with the embryonic development, both testicles start to descend towards the scrotum, among which the left testicle starts to descend earlier than the right one, and when the baby is born, some have already descended to the scrotum, but their position is higher than the left testicle; some descend later, forming a hernia; some simply stop somewhere and no longer descend, becoming cryptorchid. It seems that there is competition in the world, no wonder many parents are so willing to spend so much money on educating their children, because they are afraid that their children will lose at the starting line of life.
