摘　　要：睾丸内的精子虽已成型,但仍需要在附睾中经过一系列修饰,使形态结构和功能进一步变化,才能获得运动和受精能力,这个过程即精子成熟。与哺乳动物相比,家禽附睾发生一定退化,但近年来越来越多的研究表明家禽附睾对精子成熟有调控作用。在畜禽良种繁育体系中,精子功能直接与繁殖效率高度关联,影响制种成本和养殖效益。因此,挖掘家禽精子功能和精液品质的调控机制,对于改善雄性不育、建立家禽繁殖性能的选育方法和改良技术具有重要的应用价值。本文将对家禽附睾功能及其对精子睾丸后成熟的作用机制研究进展进行综述,以期为进一步研究附睾的家禽繁殖性能调控机制奠定基础。Spermatozoa that produced in the testis still need to undergo chemical modification, morphological and functional changes during epididymal transition to gain the motility and fertility capacity, which is named sperm maturation. Compared with mammals, the epididymis of poultry is somewhat degenerated. In recent years, more studies have proven that the epididymis has a certain regulatory effect on sperm maturation. In the livestock and poultry breeding and propagation system, male semen quality directly affects the mating ratio and related with the propagation efficiency and benefit.Therefore, exploring the regulatory mechanism underlying sperm function and semen quality has important application value for improving male sterility, establishing breeding methods and technique for improved reproduction performance. This article reviews the research progress of epididymis function and the mechanism of post-testicular sperm maturation in poultry, aiming at inspiring future research on this topic.
