Contractile activity of the muscular coat of the epididymis wall is considered the major driving force for the propulsion of sperm through the male reproductive tract.
Region-specific changes in the status of membrane thiols and the free radical scavening potential of the male reproductive tract of the rat were observed.
The present study shows that the local biochemical milieu has some influence on the transport of spermatozoa through the male reproductive tract. The vas deferens showed a higher level of superoxide dismutase activity and a low profile of thiol exposure.
We conclude that the strong scavenging potential and the lesser thiol exposure of the vas create an apparently inert vas lumen which facilitates the transit of spermatozoa through the vas.
附睾管壁肌层的收缩活动被认为是精子通过雄性生殖道推进的主要驱动力。
观察了大鼠雄性生殖道膜硫醇状态和自由基清除潜力的区域特异性变化。
本研究表明，局部生化环境对精子通过雄性生殖道的运输有一定影响。输精管显示出较高水平的超氧化物歧化酶活性和较低的硫醇暴露情况。
我们得出结论，输精管强大的清除潜力和较少的硫醇暴露形成了一个明显惰性的管腔，有利于精子通过输精管。
