Since an examination is reported by Skabbeck saying that the number of sperms of tunics in this present age is decreased in half comparing the one of 50 years ago, re-examinations were conducted in various countries. Although many reports show the tendency of decrease in number, sonic reports show negative results : thus the detail is not clear yet.In the present study we first carried out a set of questionnaire survey to the male students of Tottori University. Then for 73 students who agreed to offer their semen, we conducted sperm and blood tests to obtain the data of the relationships between the reproduction function and the everyday exercise habit, life style and so on in healthy young men. The results showed that the average sperm number of 120 millions in our test did not show any sign of sperm decrement comparing to 50 years ago and it is significantly above the lowest criterion of 20 millions given by the WHO.Tue average volume of semen of 2.93 ml was also well above the lowest criterion of 2.0 ml by the WHO.The average linear motion ratio of 56.5 % was also slightly over the lowest critcrion of 50 % by the WHO.In comparison between the exercise group and the control there was no difference in the number of sperms. The volume of semen and the motion ratio were barely larger in the control than exercise group but there was no statistical significance. TG was significantly lower in the exercise group than the control (p<.05). There was no significant difference in T-Cho between the groups. There observed significant correlation between the number of sperms and the sperm motion ratio (p<.01), between the sperm motion ratio and the volume of semen (p<.05) as well as the sperm motion ratio and TG (p<.05).

由于Skabbeck报告了一项检查，称与50年前相比，当今时代的被膜精子数量减少了一半，因此在各个国家进行了重新检查。虽然许多报告显示出数量减少的趋势，但声音报告显示出负面的结果，因此细节尚不清楚。本研究首先对鸟取大学的男生进行了一套问卷调查。然后对73名自愿提供精液的学生进行精子和血液检查，以获得健康青年男性生殖功能与日常运动习惯、生活方式等的关系数据。结果表明，本试验的平均精子数为1.2亿个，与50年前相比，精子数无明显减少，明显高于世界卫生组织规定的最低标准2000万个，平均精液量为2.93 ml，也高于世界卫生组织规定的最低标准2.0 ml，平均直线运动率为56.5%精子数也略高于世界卫生组织规定的最低标准50%，运动组与对照组相比，精子数无差异。对照组精液量和运动率略高于运动组，但无统计学意义。运动组的TG明显低于对照组（p<.05）。两组间T-Cho无显著差异。精子数与精子活动率之间存在显著相关性（p<0.01），精子活动率与精液量之间存在显著相关性（p<0.05），精子活动率与TG之间存在显著相关性（p<0.05）。
