RESUMO
In this study, concerning 86 patients submitted to surgical exploration for sterility, has been achieved with a double objective to determines the precise histological nature of the lesions of the sperm ducts mainly of the epididymis and determine the etiological diagnosis of the epididymal obstruction. We've showen that whatever the level of the acquired obstruction of the epididymis, it will lead to the formation of an inflammatory home and to a situation combining the lessening of light, stase and massive arrival of spermiophage of destroying almost completely the spermatozoa. The simultaneous consideration of the 2 values of the <-glucosidase and the plasma FSH permit of reducing the mistakes in interpreting the origin of azoospermia. However we have produced evidence of diagnostic traps corresponding to a fibrose of rete testis where all the biological parameters are normal. W've showen that, there is a correlation between the presence of epididymal pathology and a drop in epididymal markers which can be found in severe oligospermia [which can be epididymal in origin and not testicular], also when there is non abnormalities in the spermogramm. This last situation can occur in " invisible" abnormalities of sperm maturation in the epididymis
