Variations in plasma testosterone, dihydrotestosterone. delta 4 androstenedione, LH, FSH and cortisol were measured before and after 6 succesive effort tests in 11 male subjects. Testicular secretion and the extra-hepatic consumption of androgens are increased by the haemodynamic conditions of effort but plasma levels of testosterone and dihydrotestosterone fall with repeated effort, indicating a progressive imbalance between production and consumption. These variations suggest that the testis, rather than glucocorticoid function of the adrenal, might play a major limiting role, psychological and metabolic, in tolerance of prolonged effort.
在11名男性受试者进行6次连续的耐力测试前后，测量了他们血浆中的睾酮、双氢睾酮、δ4雄烯二酮、促黄体生成素（LH）、促卵泡生成素（FSH）和皮质醇的变化。耐力测试的血流动力学状况会增加睾丸分泌以及雄激素的肝外消耗，但随着反复测试，血浆中睾酮和双氢睾酮的水平会下降，这表明在产生和消耗之间逐渐出现了失衡。这些变化表明，在长时间耐力的耐受性方面，睾丸而非肾上腺的糖皮质激素功能可能在心理和代谢方面发挥主要的限制作用。
