There is a suggested pathophysiology associated with endometrial microbiota in cases where repeated implantation failure of high-quality embryos is observed. However, there is a suspected association between endometrial microbiota and the pathogenesis of implantation failure. However, there is still a lack of agreement on the fundamental composition of the physiological microbiome within the uterine cavity. This is primarily due to various limitations in the studies conducted, including small sample sizes and variations in experimental designs. As a result, the impact of bacterial communities in the endometrium on human reproduction is still a subject of debate. In this discourse, we undertake a comprehensive examination of the existing body of research pertaining to the uterine microbiota and its intricate interplay with the process of embryo implantation. •There is a suspected association between endometrial microbiota and the pathogenesis of implantation failure.•Impact of bacterial communities in the endometrium on human reproduction is still a subject of debate.•This knowledge is crucial for comprehending the factors that influence fertility and the maintenance of a successful pregnancy.
