It is relatively late to operate on an 8 1/2 year old left cryptorchid testis in the groin, but surgery should be performed aggressively during this period to prevent delays. Generally speaking children with cryptorchidism are recommended to have surgery from 6 months to 12 months after birth, and no later than 18 months, the higher the cryptorchid position, the earlier the surgery. Surgery at 8.5 years of age is also possible, but the results may be poor. In general, it is recommended that the child be operated on as early as possible. Prolonged exposure of the testis to temperature in the inguinal region can lead to abnormal spermatogenesis, as well as decreased sperm quality, and long-term cryptorchidism carries the risk of testicular cancer. Therefore, cryptorchidism in the inguinal canal should be detected and treated early. It is not necessary to be overly alarmed when discovering cryptorchidism, and it is recommended to go to regular hospitals as soon as possible to determine the diagnosis and treatment plan, and actively diagnose and treat, so as not to affect the reproductive function of the patient.
