For the treatment of pediatric cryptorchidism, early treatment should be given regardless of unilateral or bilateral cryptorchidism, and endocrine treatment should be preferred for those who are not accompanied by inguinal hernia. The methods of endocrine therapy include: first, chorionic gonadotropin (HCG) method, HCG 1500 units every other day by intramuscular injection for 9 times; second, luteinizing hormone-releasing hormone (LHRH) therapy, LHRH 40mg, nasal mist 3 times a day for 4 weeks; third, LHRH + HCG method, first LHRH 1.2mg/d, nasal mist in 3 times, then HCG 1500 units after 4 weeks units once a week for 3 times. For those who have not descended with endocrine therapy, it is best to operate before two weeks of age, and the method is internal fixation of testicular descent.
