[Testicular biopsy findings following orchiopexy].

320 testicular biopsies were evaluated from the years 1974 to 1984 and in (5.9%) cases an orchiopexy in the history of patients were found. The orchiopexy was made in 14 cases on both and in 5 cases on one site. Average age was 8.1 years during the operations and it seems to be very high. The spermiograms of these cases showed severe oligozoospermia and azoospermia. Histological investigation of biopsies demonstrated mild to severe hypospermatogenesis with and without maturation arrest and Sertoli cell and Klinefelter's syndrome. In the testicular biopsy from one patient were found granulomas with foreign material as talc which induced regional fibrosis.
