In this study the frequency distribution of sperm counts and total sperm counts from more than 4000 allegedly fertile males were compared with those of husbands in 1000 infertile couples. Significant differences were observed only at the lower end of the scale (sperm counts below 10 million/ml and total sperm counts below 25 million/ejaculate). Frequency distributions of sperm counts above 10 million/ml or total sperm counts above 25 million/ejaculate revealed little difference between the fertile and infertile groups. These data suggest that, unless other parameters are found to be abnormal, sperm counts and total sperm counts above 10 million/ml and 25 million/ejaculate, respectively, probably are not major factors in a couple's infertility.
在本研究中，将4000多名据称具有生育能力的男性的精子计数和总精子数的频率分布，与1000对不育夫妇中丈夫的精子计数和总精子数的频率分布进行了比较。仅在较低水平（精子计数低于1000万/毫升和总精子数低于2500万/射精）观察到显著差异。精子计数高于1000万/毫升或总精子数高于2500万/射精的频率分布显示，可育组和不育组之间几乎没有差异。这些数据表明，除非发现其他参数异常，否则精子计数和总精子数分别高于1000万/毫升和2500万/射精，可能不是夫妻不育的主要因素。
