Spermatogenesis arrest is known as the interruption of  germinal cells of specific cellular type, which elicits an altered spermatozoa formation. Spermatogenic arrest is usually due to genetic factors resulting in irreversible azoospermia.
Spermatogenesis arrest indicates a stop in the specific germinal cells, which leads to abnormal sperm formation. This typically results from genetic factors that cause irreversible azoospermia.
