[Length-growth of seminiferous tubules of untreated and as surgically displaced, congenitallydystopic testes in children and adolescents].

The total length of the seminiferous tubules of congenital dystopic testicles was calculated from bioptical preparations. 55 untreated testicles, 79 unilaterally and 78 bilaterally operatively displaced testicles as well as 78 contralaterally eutopic testicles were evaluated. During the whole prepuberal phase of life in the congenital dystopic testicles a nearly continuous growth of the length of the seminiferous tubules takes place. The total length of the intrascrotally displaced testicles is larger than the length of untreated testicles corresponding to age. After the operative correction of the position of congenital dystopic testicles an acceleration of the growth of the length of the tubule begins.
