After bilateral cryptorchidism surgery, most of them can have children normally. Studies have shown that bilateral cryptorchid infertility is up to more than 50% and unilateral cryptorchid infertility is up to more than 30%. For diagnosed bilateral cryptorchidism, early cryptorchidism descent surgery is recommended, because cryptorchidism is in the retroperitoneum and inguinal canal, where the temperature is 1.5-2 degrees higher than that of the scrotum, and the spermatogenic function of the normal spermatogenic tubules of the testes will be damaged, leading to sperm disorder, which will eventually lead to infertility. It is recommended that after the diagnosis of cryptorchidism is confirmed, surgery should be performed at an early stage, and generally two years old should be mandatory. If it is not detected in time, it is recommended that surgery must be performed before the age of twelve, and if surgery is performed after the age of twelve, the incidence of infertility will be very high.
