title: [Severe oligozoospermia as a sequela to partial obstruction of the seminiferous tubules].
abstract: Arguments for the presence of a partial obstruction as cause of severe oligozoospermia may result from following findings. 1. The frequency of normal FSH values in oligozoospermia (44.9%) do not differ significantly from cases with azoospermia (50%). 2. Including a quantitative analysis of testicular morphology 5 out of 63 patients (7.9%) suffering from severe oligozoospermia show a normal spermatogenesis. 3. The frequency of this constellation in our material including severe oligozoospermia, normal testicular volume, normal FSH value, and normal spermatogenesis agree with few findings in the literature. The number of etiological factors of partial obstruction require also invasive diagnostical procedures like vas deferens radiography and surgical exploration.
