Undescended Testes

Undescended testes occur in less then 4% of children and are more common in premature babies. Many “undescended” testes are simply retractile and can be brought down by hand, these do not need surgery.  However others are true undescended testes and will need surgery usually between 9 and 12 months of age.
If undescended testes are not treated there may be problems in adult life with infertility or an increased risk of cancer of the undescended testis.
At the appointment, Anne will examine your child carefully to see if the testis can be felt in the body. If the testis can be felt, a simple operation under general anaesthetic (putting your child to sleep during the operation) would be performed between 9 and 12 months of age. If the testes cannot be felt, a different type of operation would be performed so that the surgeon can check where the testes are. In some cases, the testes are absent.
