睾酮是男性体内主要的雄激素。老年男性体内睾酮水平下降使机体呈现肌肉松弛、骨质疏松和性欲减退等衰老现象,这与睾酮合成减少及其分泌节律改变密切相关。除了肾上腺皮质有少量分泌以外,睾酮主要由睾丸间质中的Leydig细胞生成。对于衰老Leydig细胞中睾酮合成减少的机制的研究 Testosterone is the major androgen in men. Decreased testosterone levels in the elderly male body so that the body showed aging, such as muscle relaxation, osteoporosis and loss of libido, which is closely related to reduced testosterone synthesis and changes in its secretion rhythm. In addition to a small amount of secretion of the adrenal cortex, testosterone is mainly produced by Leydig cells in the testicular stroma. Study on the mechanism of testosterone synthesis reduction in aged Leydig cells
