Cryptorchidism is a minor surgery, it is a relatively common surgery in urology, most cryptorchidism is in infants and children, this requires surgery under general anesthesia, a few are adults, only spinal anesthesia also known as lumbar anesthesia is needed. In most cases, the testicle is located in the inguinal canal or in the groin, and the surgery is relatively simple in this position, the testicle is fully freed, descended and fixed in the scrotum. Under normal circumstances, the testicles have already descended into the scrotum when the child is born. If they do not descend into the scrotum, it is called cryptorchidism, and the best age for cryptorchidism surgery is usually 1-1.5 years old, and usually no more than 2 years old before the surgery.
