Testosterone levels in plasma in 50 young males are found on a plateau between 07,00 h and 10,00 h. As this plateau represents the highest level throughout the day, it is necessary to take blood sample only once during this period. Therefore a statement about endocrine testicle function can be given by only one determination of testosterone between 07,00 h and 10,00 h. This faciliates endocrine examination in ambulant patients.
研究发现，50名年轻男性血浆中的睾酮水平在07:00至10:00之间处于平稳状态。由于这一平稳期代表了全天的最高水平，因此在此期间只需采集一次血样。所以，仅通过在07:00至10:00之间测定一次睾酮，就能对睾丸内分泌功能作出判断。这有助于对门诊患者进行内分泌检查。
