摘要
附睾是男性生殖系统的重要器官之一,负责精子的成熟、转运和储存。附睾功能的实现依赖于其旺盛的生理活性,因而自由基的产生不可避免。自由基过度积累势必造成附睾氧化应激,精子质膜及其DNA发生氧化损伤,极大影响精子运动和受精能力的获得,从而造成男性不育。本文对附睾氧化应激在能量代谢、炎症反应等过程中的产生机制和超氧化物歧化酶、过氧化氢酶、谷胱甘肽过氧化酶、吲哚胺双加氧酶、还原性谷胱甘肽及硫氧还蛋白等物质的抗氧化作用进行了综述,以期为男性不育症的有效预防、诊断和治疗提供新思路。
The epididymis is an important organ in the male genital system, which is responsible for the maturation, transportation and storage of spermatozoa. The proper function of the epididymis is closely related with its robust physiological metabolism, and free radicals are inevitably produced as a consequence. An excess of free radicals would lead to the oxidative stress of the epididymis, damage the sperm membrane and DNA, seriously affect sperm maturation and result in male infertility. This article reviews the mechanism of epididymal oxidative stress in energy metabolism and inflammatory reaction as well as the roles of superoxide dismutase, catalase, glutathine peroxidase, indoleamine 2, 3 dioxygenase, glutathione and thioredoxin in the antioxidant process, offering a new insight into the prevention, diagnosis and treatment of male infertility.
