Nomenclature of cryptorchidism.

Despite the fact that cryptorchidism is a common congenital anomaly, our understanding of this problem is hampered by confusion and uncertainty regarding diagnosis and treatment. A major factor producing this confusion is the lack of a common terminology that describes to the reader (or listener) exactly what the author means by a given term. Herein is proposed a classification system that, if adopted and utilized, could ameliorate this problem.
