The microbiota is composed of numerous resident microorganisms, which contribute to the health and illness of the individual. When the microbiota is in dysbiosis, it can cause some pathological processes and in man it can be correlated with the male infertility, so the present study sought through a review systematic identification of whether there is a correlation between the microbiota and seminal quality. Were analyzed 7 research articles in PubMed, Medline and Cochrane library databases, in English and published between 2012 and 2022. In men with normal semen parameters, a higher prevalence of Lactobacillus. A higher prevalence of Prevotella was observed in patients who had some seminal alteration. We conclude that the microbiota is correlated with seminal quality, since the decrease in Lactobacillus and the increase in of other species is seen in infertile men.
