Using a sample of 33 healthy young men, 6 blood samples were obtained in the course of 2 weeks, and testosterone, dihydrotestosterone, and estradiol levels determined. The amount of free testosterone in the saliva was also ascertained for 23 of the subjects. All participants kept a daily record of their sexual activity during the investigational period. An interindividual comparison revealed a significant positive correlation between serum testosterone levels and the frequency of orgasms as well as a significant negative correlation between estradiol concentrations and the frequency of sexual activity without orgasm. The comparison of hormone levels to sexual behavior, prior to and after the individual sampling, reveals significant positive correlations between the serum testosterone and the extent of the free testosterone on the one hand and both the preceding and subsequent frequency of orgasms on the other. The estradiol levels showed a significant negative correlation with both the preceding and the subsequent frequencies of sexual activity without orgasm.
以33名健康年轻男性为样本，在2周内采集了6份血样，并测定了睾酮、双氢睾酮和雌二醇水平。还对其中23名受试者的唾液游离睾酮量进行了测定。所有参与者在研究期间每天记录其性活动情况。个体间比较显示，血清睾酮水平与性高潮频率之间存在显著正相关，雌二醇浓度与无性高潮性活动频率之间存在显著负相关。个体采样前后激素水平与性行为的比较显示，血清睾酮和游离睾酮水平一方面与之前和之后的性高潮频率之间存在显著正相关。雌二醇水平与之前和之后无性高潮性活动频率均呈显著负相关。
