How do i check my 3 year son's testicles to make sure they are descended? his pedatrcian could not find his left testicle at his check up last week

Clarify with Ur doc: If it was hiding in the folds of the groin, it will sometimes come down in a warm bath. If the doc couldn't detect it at all and or it doesn't come down when relaxed, he needs to see a urologist and have it located and brought down, These form next to the kidneys and migrate down during pregnancy.Some never complete the trip and failure to come down by a year needs attention.
