title: [Determination of the total length of seminiferous tubules in normally descended testes in children].
abstract: The total length of all seminiferous tubules of a testicle can be determined with the help of histomorphometric investigation methods. Two different methods are described and discussed. For this purpose bioptically got specimens of parenchyma of the size of a rice-grain are sufficient. In children the total length of the tubules constantly increases. During the prepuberal phase of life an acceleration of the growth of the length of the seminiferous tubules begins. The results of 89 autoptically got and morphometrically examined testicles of children are reported.
