[Use of the 25-point ocular grid plate in quantitative-morphological studies of eutopic and dystopic testes of children].

From plains histologic preparations of children's testicles the volume of seminiferous tubules and extratubular tissue were calculated by use of the points counting method. In ectopic testicles, the extratubular part is significantly larger than in normally descended testes. The range of the values measured by this method diminishes the higher the total count of test points is. The 25-points-test-net of VEB Carl Zeiss Jena in particular met all requirements for quantitative examinations of the morphology of testicles.
