精浆蛋白质对家畜精子功能的研究进展

Research Progress on Seminal Plasma Protein on Sperm in Mammals

精浆主要由睾丸、附睾、输精管以及副性腺的分泌物混合而成,它被认为与精子存活和保护精子在雌性生殖道中抵抗免疫系统的攻击有关。蛋白质作为精浆中含量最丰富的成分之一,其与精浆的功能息息相关,已有许多研究关注精浆蛋白对精子功能的影响,并试图鉴定其作为雄性生育力标志物的潜力。本文综述了精浆的主要组成成分及不同家畜的精浆蛋白质组成,总结了不同家畜精浆蛋白质对精子功能的影响,为进一步了解家畜精浆的生理功能及其影响雄性繁殖力的作用机制提供更多参考。

Seminal plasma,a fluid formed by the secretion of testis,epididymis,vas deferens and male accessory glands,plays a crucial role in the sperm viability and protect sperm from the attack of female reproductive tract immune system.Proteins constitute one of the most abundant components in seminal plasma,and bear a profound connection to the functional properties of this complex mixture.Current research focuses on understanding the impact of seminal plasma proteins on sperm function and identifying their potential role as biomarkers for male fertility.This review described the main components of seminal plasma,and analyzed the kinds of seminal plasma protein in different livestock species.And then,the paper discussed the functional effects of seminal plasma proteins on sperm in various livestock.The insights gained from this paper contribute to a better understanding of the physiological functions of seminal plasma in livestock and provide a solid foundation for exploring reproductive physiology in male animals and enhancing male reproductive performance.
