Recent studies on the characterization of the seminal microbiota have identified key factors associated with animal fertility, particularly influencing sperm quality. The use of Next Generation Sequencing (NGS) technologies and the development of advanced analytical tools have allowed for a more comprehensive characterization of the microbial communities present in semen, revealing a much greater diversity than previously anticipated. These methodologies have made it possible to investigate microorganisms that are either present in low abundance or difficult to culture, as well as to explore the composition and abundance of these populations under different conditions. Within this context, the objective of this work was to describe and discuss the main advances regarding: (i) microbial characteristics associated with sperm quality; (ii) the effects of the gut microbiota on male reproductive performance; (iii) external factors involved with the modulation of these communities; and (iv) practical implications and future perspectives for swine reproduction.
