[Cytologic assessment of spermatogenesis disorders in male sterility].

The cytologic method for the assessment of spermatogenesis disorders is based on the examination of the testicular biopsy specimen smears-impressions; it permits a qualitative and quantitative estimation of spermatogenous epithelial cells. The investigation is made on the day of the operation, this essentially accelerating the diagnosis of this abnormality. Spermatogenesis cessation or inhibition is determined on the cytogram at the level of the most 'mature' population of the germinative epithelium.
