The motility of the spermatozoas.: Literature review.: Part 1.: The structure of the motility and its assessment

The review article discusses the morphological and functional structures such as the plasma membrane, the mitochondria, the flagellar microtubular system and the biochemistry of the motility, whose coordinated functions produce and maintain the motility of the sperm cell. The alternative methods of the evaluation for these structures used partially or completely in daily sperm assessment are also discussed because their knowledge becomes more and more important by the spread of the assisted reproductive technologies.
