Histopathology of various<unk>  disorders.<unk>  is known as the interruption of germinal cells of specific cellular type, which elicits an altered spermatozoa formation. Spermatogenic<unk>  is usually due to genetic factors resulting in irreversible azoospermia. However some cases may be consecutive to hormonal, thermic, or toxic factors and may be reversible either spontaneously or after a specific treatment. Spermatogenic<unk>  results in either oligospermia or azoospermia in men. It is quite a difficult condition to proactively diagnose as it tends to affect those who have normal testicular volumes; a diagnosis can be made however through a testicular biopsy. Effects== Spermatogenic<unk>  results in either oligospermia or azoospermia as mentioned above. Oligospermia is when extremely low concentrations of fertile sperm are found in semen or ejaculate, while azoospermia is when no fertile sperm are found in the semen or ejaculate.
