This condition affects newborn babies or the very young. At birth, one or both testicles are not yet in the Scrotum.  This normally resolves within the first month, with the Testicle(s) normally dropping down from the groin, but when this doesn’t happen, a small operation may be required.
    
The longer this condition continues the more of a problem it becomes.  If not resolved by the age of 10, the undescended testicle may have to be removed completely.
