Abstract:

Semen quality is an important reference index for selecting good breed male livestock and poultry. Intestinal microorganisms not only can regulate gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T) and other reproductive hormones through the gut-testis axis, but also regulate the synthesis and metabolism of butyric acid, amino acids, vitamins, bile acids, gas signaling molecules (H2S、NH3 and NO), gamma-aminobutyric acid (GABA) and 5-hydroxytryptamine (5-HT) in the intestine, thereby regulating semen quality.Therefore, increasing the level of suitable microorganisms or their metabolites in the gut can improve the semen quality of male animals. This paper reviews the research progress on the regulation of semen quality by animal gut microbes and their metabolites, to guide production practice.

Key words: semen quality, gut microbe, reproductive hormones, metabolites
