It is said that the male baby’s “balls” are a magical thing. I, “balls” of the moving journey male fetus in the process of development in the womb, testicles are not directly in the scrotum development, but first in the abdominal cavity development, as the gestational age increases, testicles will follow a tube (inguinal canal) gradually descend to the scrotum, generally to the birth of testicles have descended to the scrotum to settle down. A few male children, especially those born prematurely, are born with one or both testicles not yet ready to descend into the scrotum, and most of them gradually complete the process of testicular “moving” in the first month after birth. However, for some male babies, the testicle moving process is affected by various factors, and the testicles will never descend into the scrotum, and the scrotum that should have testicles is empty, which is medically known as cryptorchidism. The testicles are the organ for synthesizing sperm. If the testicles of a child do not descend, especially if they remain in the abdominal cavity (where the temperature is higher) until he is over two years old, there is a great risk that he will not have a chance to become a father in the future, and the risk of testicular tumors will also increase in adulthood. How parents can check their boy’s “balls” a When the room temperature is warm enough, the child should lie flat on his back or sit up with his legs spread outward. b Parents keep their hands warm to avoid cold stimulation of the testicles when touching. c Touch both sides of the scrotum with both hands at the same time to see if there is a testicle. If the child has cryptorchidism, the scrotum will look smaller and appear underdeveloped, and if there is only one side of cryptorchidism, the scrotum on both sides will look asymmetrical. d If you cannot touch the testicles or if the testicles retract, you should consult a specialist in time to find out the next step of treatment. How to bring the lost “balls” home Usually, treatment is considered when the testicles have not descended into the scrotum around the age of half to one year. Most children with cryptorchidism need surgery. Some “balls” are not completely lost, but just hide and seek. Most boys’ testicles, although they have descended, usually stay in the scrotum, but in some cases they will “hide and seek”, for example, when they are excited or cold, they may temporarily “disappear” and hide in the scrotum. For example, they may temporarily “disappear” when excited or cold and hide in the inguinal canal. Tips: There are specialties in the field, so remember to register for “pediatric urology” and ask a specialist to check and treat your condition, as a random pediatric number may make you run more errands. “Pediatric surgery”.
