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.
The arrest of spermatogenesis is referred to as the cessation of specific germinal cells, leading to abnormal spermatozoa production. Spermatogenic arrest typically occurs due to genetic factors causing permanent azoospermia.
