Large elastic arterial stiffening and endothelial dysfunction are phenotypic characteristics of vascular aging, a major risk factor for age-associated cardiovascular diseases. Compared to men, vascular aging in women appears to be slowed until menopause, whereafter vascular aging accelerates to match that seen in men. These sex differences in vascular aging have been attributed to changes in sex hormones that occur with aging. Although the role of estradiol in vascular aging in women has been highlighted in recent aging research, little is known about the impact of declining testosterone concentrations in both sexes. Importantly, while androgen concentrations generally decline with age in men, there are data that indicate reductions in androgen concentrations in women as well. Evidence suggests that low testosterone is associated with impaired endothelial function and increased arterial stiffness in men, although the effect of androgens on vascular aging in women remains unclear. Testosterone may modulate vascular aging by mitigating the effects of oxidative stress and inflammation, although there is sex specificity to this effect. The purpose of this review is to present and summarize the research regarding sex differences in vascular aging in response to androgens, specifically testosterone. Because exercise is a potent lifestyle factor for slowing and reversing vascular aging, we briefly summarize the available literature regarding the regulatory function of testosterone on vascular adaptations to exercise training.

响应睾丸激素的血管衰老中的性别差异。

大的弹性动脉硬化和内皮功能障碍是血管衰老的表型特征,血管衰老是与年龄有关的心血管疾病的主要危险因素。与男性相比,女性的血管衰老似乎要在更年期之前减缓,此后血管的衰老会加速到与男性相同。血管衰老的这些性别差异已归因于衰老引起的性激素变化。尽管在最近的衰老研究中已经强调了雌二醇在女性血管衰老中的作用,但对于男女睾丸激素浓度下降的影响知之甚少。重要的是,尽管雄激素浓度通常随着年龄的增长而下降,但有数据表明女性的雄激素浓度也有所降低。有证据表明,尽管雄激素对女性血管衰老的影响尚不清楚,但睾丸激素水平低与男性血管内皮功能受损和动脉僵硬度增加有关。睾丸激素可以通过减轻氧化应激和炎症的作用来调节血管的衰老,尽管这种作用具有性别特异性。这篇综述的目的是介绍和总结有关对雄激素(特别是睾丸激素)的血管衰老中性别差异的研究。由于运动是减缓和逆转血管衰老的有效生活方式,因此,我们简要总结了有关睾丸激素对运动训练中血管适应性调节功能的现有文献。尽管雄激素对女性血管衰老的影响尚不清楚。睾丸激素可以通过减轻氧化应激和炎症的作用来调节血管的衰老,尽管这种作用具有性别特异性。这篇综述的目的是介绍和总结有关对雄激素(特别是睾丸激素)的血管衰老中性别差异的研究。由于运动是减缓和逆转血管衰老的有效生活方式,因此,我们简要总结了有关睾丸激素对运动训练中血管适应性调节功能的现有文献。尽管雄激素对女性血管衰老的影响尚不清楚。睾丸激素可以通过减轻氧化应激和炎症的作用来调节血管的衰老,尽管这种作用具有性别特异性。这篇综述的目的是介绍和总结有关对雄激素(特别是睾丸激素)的血管衰老中性别差异的研究。由于运动是减缓和逆转血管衰老的有效生活方式,因此,我们简要总结了有关睾丸激素对运动训练血管适应性调节功能的文献。这篇综述的目的是介绍和总结有关对雄激素(特别是睾丸激素)的血管衰老中性别差异的研究。由于运动是减缓和逆转血管衰老的有效生活方式,因此,我们简要总结了有关睾丸激素对运动训练中血管适应性调节功能的现有文献。这篇综述的目的是介绍和总结有关对雄激素(特别是睾丸激素)的血管衰老中性别差异的研究。由于运动是减缓和逆转血管衰老的有效生活方式,因此,我们简要总结了有关睾丸激素对运动训练中血管适应性调节功能的现有文献。
