The earlier the child is operated on before the age of 2 years, the better. If the child is not detected and operated on in time, it will have an impact on the child’s fertility in the future. Many doctors in adult hospitals often tell parents to operate at the age of 5 or 6, which is not true. So how do we determine if a child has cryptogram? There are several points for reference only: poor scrotal development, on one side or both sides; the testicles cannot be felt in the scrotum mainly by touching them with the hand or the testicles cannot be pulled to the scrotum by touching them above the scrotum. This is when the disease is highly suspected.
