1.Waiting therapy Normally, the testicles have already descended into the scrotum when the baby is born, but there are some babies, due to the delay of embryonic development, the descent of testicles can be delayed to 3 months to 1 year after birth. Therefore, if a baby is born with cryptorchidism, it is not necessary to use drugs or surgery to try to reset the cryptorchidism, but to wait patiently and expect the cryptorchidism to descend automatically. A study of 3,612 boys found that true cryptorchidism rarely descends after the age of 1 year, which reminds us that waiting without active measures is only appropriate up to the age of 2 years. Because cryptorchidism may lead to some undesirable complications, it should be treated in time, which at present mainly includes the following methods: 2. Hormone treatment Some patients with cryptorchidism are caused by endocrine reasons. As we mentioned earlier, the testicular descent of fetus in mother is closely related to maternal gonadotropin. Accordingly, in recent years, many scholars use LH-RH (gonadotropin-releasing hormone) and then use HCG (chorionic gonadotropin) to get a better therapeutic effect. HCG therapy treatment total amount of 10,000 to 20,000 units is appropriate, the specific method of 1,500 units every other day. Another short-term high-dose shock therapy, daily intramuscular injection 4000～6000 units for 3 days. If the treatment is effective, the testicles may descend into the scrotum 2 to 3 weeks after the drug is administered. The appropriate age for treatment is between 2 and 9 years of age, but it is not effective before or after this time. Synthesis of LH-RH intranasal spray, which consists of 1.2 mg of LH-RH (1 mg/mL) sprayed intranasally 6 times a day for 4 weeks. This method is more suitable for young children, and HCG can still be effective in those who are ineffective with this method, so the above two methods can be applied jointly. 3.Surgical treatment ①Testicle fixation, open surgery to forcibly fix the testicle in the scrotum is the most important and effective method to treat cryptorchidism, and most of the patients can be successfully treated with this method. The timing of operation is very important, too early may lose the chance of cryptorchid testis descending on its own, too late will affect the function of testis, in the past, it was advocated that the age of 2~5 years old is appropriate, the latest not more than 6 years old. In recent years, some scholars suggest that it is better to have surgery before 2 years old, the reason is that after 2 years old, the testicular tissue of the child has already undergone pathological changes. ② Testicular transplantation, with the extensive development of microsurgery, autologous testicular transplantation is used to treat high cryptorchidism with better results. The doctor will cut off the whole cryptorchid testis together with its blood vessels in an original way and “move” it to the scrotum, and then operate under the microscope to anastomose the testicular blood vessels to the arterial and venous veins under the abdominal wall carefully, so as to ensure the blood circulation of the testis. (iii) Orchiectomy, once the testicle is found to be obviously underdeveloped, shrunken and small, or soft in texture and other loss of function, cryptorchidism should be removed without mercy to prevent malignant changes in the future.
