title: Flow cytometric analysis of the maldescended testis.
abstract: Flow cytometric measurements of the cellular DNA contents of 16 testicular biopsies of 15 patients with maldescended testes were performed. 2 patients were children. 11 patients of pubescent or adult age had no haploid germ cells in the tissue of their maldescended testis. One patient with a testis mobilis had about a normal percentage of haploid germ cells. In one patient a malignant tumor was detected unexpectedly by an aneuploid stem line at 2.2 c. Flow cytometric analysis of human testicular biopsy material is an easy and a fast way to quantify the function of spermatogenesis and detect malignancies.
