Protamines were extracted from the sperm of fertile and infertile human males and the relative proportion of protamines 1, 2, and 3 were determined by scanning microdensitometry following electrophoresis of total protamine in polyacrylamide gels. The proportion of the three protamines was found to be similar in sperm obtained from different normal males. The distribution of protamines in sperm obtained from a select group of infertile males producing an elevated level of large sperm heads, in contrast, was different from that of the fertile males.
从有生育能力和无生育能力的男性精子中提取鱼精蛋白，并在聚丙烯酰胺凝胶中对总鱼精蛋白进行电泳后，通过扫描显微密度测定法确定鱼精蛋白1、2和3的相对比例。结果发现，从不同正常男性获得的精子中，三种鱼精蛋白的比例相似。相比之下，从一组特定的不育男性（其产生的大头精子水平升高）获得的精子中，鱼精蛋白的分布与有生育能力的男性不同。
