Abstract  The reproductive performance and semen quality of male livestock and poultry are of great significance to animal husbandry, and are closely related to the conception rate, litter size and survival rate of female livestock and poultry. As an important reproductive organ, the epididymis is responsible for sperm concentration, maturation (including sperm vitality acquisition and fertilization ability), protection and storage. MicroRNA (miRNA) is a kind of non coding single stranded RNA molecule with a length of about 22 nt, which is closely related to a series of physiological processes in epididymis of livestock and poultry. miRNA participates in regulating different biological processes, including sperm vitality, sperm maturation, sperm cell apoptosis, ion channel activity, copper ion detoxification, etc. This paper summarized the similarities and differences in the structure and function of epididymis between mammals and poultry, reviewed the research progress of miRNA in regulating sperm motility, maturation, ion transport and other biological functions in epididymis of livestock and poultry. This review provides reference for the research of miRNA regulation mechanism in epididymis and genetic breeding of breeding male reproductive performance.
