Abstract: Polyunsaturated fatty acids (PUFAs) are mainly divided into ω-3 PUFA and ω-6 PUFA,which are the main components of sperm plasma membrane lipid and have the effect of improving antioxidant capacity,sperm plasma membrane fluidity,sperm structural integrity and testosterone synthesis.Arachidonic acid (AA) in ω-6 PUFA could promote the secretion of testosterone,but excessive AA in seminal plasma may induce oxidative stress;Linoleic acid (LA) can also increase the level of testosterone in the body,conjugated linoleic acid (CLA) can reduce the oxidative stress of sperm;A small amount of docosapentaenoic acid (DPA) in animals can not only participate in the transport process of sperm,but also improve the antioxidant capacity of sperm.Alpha-linolenic acid (ALA) in ω-3 PUFA has antioxidant effects and can stimulate the synthesis of testosterone,docosahexaenoic acid (DHA) is similar to ALA,can improve the antioxidant capacity of sperm,at the same time can promote testosterone synthesis;Eicosapentaenoic acid (EPA) can regulate sperm structure and testosterone synthesis.An appropriate ω-6/ω-3 PUFA ratio has important regulatory effects on sperm motility,plasma membrane structure,lipid composition and acrosomal response.The effect of PUFA on semen quality may vary depending on the method of addition,type,and proportion of ω-6/ω-3 PUFA.In recent years,great progress has been made in the research of PUFA on animal semen quality,but its mechanism and related approaches to improve semen quality still need to be further explored.In this paper,the effects of PUFA on animal semen quality were summarized,and the effects of different types of ω-3 PUFA,ω-6 PUFA and ω-6/ω-3 PUFA ratio on sperm were summarized,in order to provide theoretical reference for further understanding the application of PUFA in animal semen production.

Key words: ω-3 polyunsaturated fatty acid; ω-6 polyunsaturated fatty acid; semen quality
