The treatment principle of cryptorchidism is that once it is diagnosed, it should be treated actively.1. For patients with cryptorchidism, the best time for surgery is between 1-2 weeks of age. Because some research data show that after the age of 2 weeks, the testes of patients with cryptorchidism will have obvious effects, which will easily cause the germ cells of the testes to decrease and cause spermatogenic dysfunction of the testes.2. For the treatment of the testes, there are mainly the following surgical methods: for patients with low cryptorchidism, testicular fixation surgery can be used. If there is a combination of short spermatic cord vessels, staged testicular fixation surgery can be used. If the position of cryptorchid is high and located in the abdominal cavity, laparoscopic testicular descending fixation surgery or testicular autologous transplantation can be used for treatment. For older patients with cryptorchidism who are late in treatment, the testicles usually have obvious atrophy and have lost their functions, so orchiectomy can be considered for treatment at this time.
