Whether a baby needs surgery for cryptorchidism should be effectively analyzed and evaluated according to the baby’s age. If the baby is younger than one year old, it is recommended that observation can be continued. 70% of children with cryptorchidism can descend into the scrotum on their own by current observation and analysis. If the baby is older than one year, it is recommended to use medication to see if the testicle can be descended into the scrotum. The recommended medication, chorionic gonadotropin, is given by intramuscular injection of 500 units twice a week, for a total dose of 5,000-10,000 units, and is effective in some children. If after two years of age there is still no descent into the scrotum, this condition must be operated on or it can lead to an increased incidence of infertility.
