Cryptorchidism is 20-50 times more likely to develop cancer than normal. It is recommended that all patients with cryptorchidism should be detected and treated surgically at an early stage. The vast majority of cryptorchid testes are lodged in the inguinal canal, retroperitoneum or at the entrance to the scrotum. For cryptorchid testes that have been in the retroperitoneal and inguinal canal for a long time, the temperature here is very high, so it has a tendency to become cancerous. When bilateral cryptorchidism or unilateral cryptorchidism is detected, early surgery for descending and fixation of the testicle should be performed, with a success rate of more than 95%. Cryptorchidism can also lead to spermatogenic dysfunction, so early surgery is the best option for cryptorchid patients.
