A direct blow to the scrotum or twisting of the testis and spermatic cord may cause painful swelling.
The problem may be corrected by surgery within the first few years of life.
The testicle must then be removed through the groin (a surgical process called orchiectomy).

For the children with Undescended Testis, it is recommended to have surgical correction within one year to prevent infertility in later life.
When the baby is formed in the womb, the testis is initially formed inside the baby’s belly.As the fetus (baby in the womb) grows, the testes gradually descend out of the body and reach the sac (scrotum).
When only one testis is affected, and surgery is performed at the right time, there is 80% chance for fertility and paternity.

 Undescended Testis, Cincinnati Children's Hospital Medical Center
The terms undescended testis and cryptorchidism refer to a relatively common condition in which the testis has not descended into the scrotum and cannot be brought into the scrotum with external manipulation.
This is the most important concern for the child with an undescended testis, and concern is still greater when both testes are affected.
Psychological considerations - Although an undescended testis is of little concern to the young child, the increase in body awareness that occurs during adolescence may cause considerable concern.

 ABSENT TESTIS IN SCROTUM - Pediatric Oncall
A fourth reason for early surgery is that the likelihood of cancer in that testis which may occur later in life is more in non-descended testes and the longer they are allowed to be in an abnormal position, the higher the chances of undergoing malignant changes.
Another reason for surgery is that in 70 % of children with this condition, there is an associated hernia which is holding the testis and is preventing it from coming down, and correction of the hernia will automatically free the testis and allow it to come down easily.
The child must be examined by a Pediatric Surgeon as soon as the parents detect the absence of the testis even if the child is only a few months old.
