Testosterone in plasma is measured in 50 young males in the morning and in the evening by radioimmunoassay. Peaks are found in the morning. At 07,00 h and 10,00 h the values lie on a plateau: 91,77% at 07.00 h and 90,59% at 10.00 h. The difference is not significant. Significant differences however can be noted in comparison between values in the first and second half-day. The difference between the 07.00 h value and the 16.00 h value amounts to 17,08%; between the 07.00 h value and the 19.00 h value, to 22,6%.
采用放射免疫分析法，在早晨和晚上对50名年轻男性的血浆睾酮进行测量。早晨发现有峰值。在07:00和10:00时，数值处于平稳状态：07:00时为91.77%，10:00时为90.59%。差异不显著。然而，上下午数值比较时可发现显著差异。07:00时的数值与16:00时的数值之差为17.08%；07:00时的数值与19:00时的数值之差为22.6%。
