Abstract

Histological changes in the contralateral testis in 8 prepubertal children whose ages ranged from 3 to 7.5 years with a history of testicular torsion and subsequent atrophy were studied. The following histological parameters were evaluated: fertility tubular index (FTI), Sertoli cell index (SCI) and minimum tubular diameter (MTD). According to our findings and following Nistal and Paniagua's classification (1984) for tubular alterations, we found 5 cases (62.5%) who present the following alterations. Type 1 (case 2): FTI was decreased above 50% corresponding to slight germinal hypoplasia with normal MTD and SCI. Type 2 (cases 3 and 5): testis with remarkable germinal hypoplasia; FTI was between 30 and 50% while MTD was below normal values. Type 3 (case 8): testis with diffuse tubular hypoplasia; FTI was below 30%, whereas MTD showed 33% decrease regarding normal values. Type 4 (case 6): testes with hyperplasia of Sertoli cells; SCI was increased one third with regard to that corresponding to his age; FTI showed severe hypoplasia of germ cells. No relationship between alterations in either the age of the patients or the time elapsed since the torsion was observed. Because of all these facts and the young age of our patients, we believe that the alterations found in the contralateral testis were due to congenital dysgenesia.
