[Evaluation of congenital-cryptorchid testicles after surgical treatment (author's transl)]

The volume of 271 congenital-cryptorchid testicles which were subject to surgical treatment was compared with that of 128 descended testicles of patients of the same age. Undescended testicles, also after successful surgical treatment, remain smaller on volume than descended ones. By means of the hitting method of the point counting technique the proportion of all seminiferous tubules in the total volume of one gonad can be calculated. The seminiferous tubules of congenital-cryptorchid testicles, also after intrascrotal replacement, maintain an essentially smaller proportion concerning the total volume as in descended testicles. Among the numerous methods of surgical treatment preference must be given to those which are especially favourable to the parenchyma.
