Testicles develop in the abdomen, and gradually migrate to the scrotum at or soon after birth.
At times they may not be in the scrotum, but may be lying in the passage between the abdomen and the scrotum i.e,.along the passage of migration.
They may be pulled back into this passage due to exposure to cold, when the child cries or is frightened for some reason. At times there may be a membrane-like barrier which prevents the testicles from coming down into the scrotum.
Only if the testes do not come down till about 5 years of age, should an operation be considered.
It is best to consult your doctor rather than discuss the problem with your neighbours or friends and get confused advice.
Besides, it is embarrassing for the child to have his problem discussed in front of everyone and feel that he is different from other boys, or to be examined again and again by different people.
