title: [Ultrastructural abnormalities of the human spermatozoa: a way to study the processes of sperm differentiation].
abstract: Quantitative ultrastructural analysis of abnormal human spermatozoa allows to elucidate processes and cellular constituents involved in the spermatid differentiation. Data lead to investigations in immunocytochemistry. The factors involved mainly concern cytoskeletal elements as in the case of round-headed spermatozoa, macrocephalic spermatozoa and spermatozoa with flagellar architectural anomalies.
