Children’s diseases are slightly different from adult diseases. Many diseases in adults have little effect on function because their own development has been stereotyped, while children may not be consistent in their performance at all ages of onset, and may not achieve satisfactory results even if corrected as they mature!!! As in the case of cryptorchidism surgery, it is generally recommended to complete it within 2 years of age, because the age of 1 to 2 years is very critical for the development of the testicles! If the disease is not treated in a timely manner, it will often affect the function of the testicles later.
