Cryptorchidism in children over 6 months of age should be treated as soon as it is detected. The most common surgical procedures for children with cryptorchidism are testicular descent and fixation or laparoscopic testicular descent and fixation. Surgery is necessary for children with cryptorchidism because of the many effects it has on human health. The testicles of cryptorchidism patients are located in the abdominal cavity or in the groin, and the local temperature is 2°C higher than the normal temperature in the scrotum, and this high temperature environment tends to cause testicular atrophy and softening of the testicles. In addition, it is easy to cause the spermatogenic cells of the testes to decrease and affect the spermatogenic function of the testes. In the case of bilateral cryptorchidism patients, it usually causes infertility. In addition, due to the existence of cryptorchidism, it is easy to twist the testicles, and the incidence of testicular cancer in cryptorchidism patients will be increased. Therefore, after cryptorchidism is found in children, active surgery is still needed.
