Diagnosis

If your son has a testicle not located in the scrotum, his doctor will determine its location in the groin. Once it's located, the doctor will attempt to guide it gently into its proper position in the scrotum.

Your son may be lying down, sitting or standing during this examination. If your son is a toddler, the doctor might have him sit with the soles of his feet touching and knees to the sides. These positions make it easier to find and manipulate the testicle.

If the testicle is a retractile testicle, it will move relatively easily and won't immediately move up again.

If the testicle in the groin immediately retreats to its original location, it's most likely an undescended testicle.
