The Influence of the Vaginal Microbiome on Clinical Pregnancy in Patients Undergoing a Euploid Embryo Transfer

Microorganisms such as bacteria live naturally on and in the bodies and are of great importance for our health. In the female body, almost 10% of all microorganisms live in the reproductive organs and especially in the vagina. Healthy bacteria in the vagina can defend against harmful bacteria and infections. However, it occasionally happens that the balance between healthy and harmful bacteria is disturbed, and it is believed that this could potentially harm pregnancy. However, there is not much evidence to prove a connection between an imbalance in bacteria and having an unsuccessful pregnancy. For this reason, the goal of our study is to determine if women with certain vaginal bacteria are more likely to experience pregnancy failures. If the investigators find this to be true, patients undergoing fertility treatment might be recommended regular tests in the future. If an imbalance in bacteria is found, doctors could provide treatment to restore a healthy vaginal environment, potentially improving the chances of a successful pregnancy.
