About the timing of pediatric cryptorchidism surgery: the incidence of cryptorchidism in newborns does not change greatly, whether it is bilateral or unilateral. Bilateral cryptorchidism can be observed until about half a year old, and some children can descend naturally; unilateral children can be observed for a shorter period of time and also have a certain chance of descent. For testicles that cannot descend to the scrotum, surgery is usually required before one year of age. Some parents may ask if it is possible to operate at the age of half a year or earlier, but of course it is possible, but there is a higher chance of damage or danger to the child. Therefore, the best time for surgery is between the ages of half and one year.
