How will I know if my baby has an undescended testicle?
Your doctor can tell whether your baby has an undescended testicle by checking the baby's scrotum. If your doctor can't feel the testicle inside the scrotum, it's called a "nonpalpable" testicle. A nonpalpable testicle might be inside the abdomen, too small to feel or not there at all. It's important to find out which one is the reason. Your doctor may perform an X-ray or ultrasound to locate an undescended testicle.
