In this paper the peculiar case of an infertile man, possessing only normally shaped, but stiff and immotile spermatozoa is described. All the sperm are conventionally structured, with the constant characteristic of the absence of central tubules and projections forming the so-called central sheath. Electrophoretic analysis of the high molecular weight polypeptide chains attributed to dyneins shows the constant absence of one chain. The importance of the central structure, usually belonging to the "9 + 2" model spermatozoa, and the possible localization of a dynein chain in this region are discussed.
本文描述了一名不育男性的特殊病例，其精子形态正常，但僵硬且无活动能力。所有精子结构正常，其特征是始终缺少构成所谓中央鞘的中央微管和突起。对归因于动力蛋白的高分子量多肽链进行的电泳分析表明始终缺少一条链。文中讨论了通常属于“9 + 2”模式精子的中央结构的重要性以及动力蛋白链在该区域的可能定位。
