The vaginal microbiota is made up of 100 million to 1 billion microorganisms per milliliter of vaginal secretions. According to a new study, an imbalance of this microbiota can be responsible for a miscarriage. We explain to you.
One in ten women have had a miscarriage
According to a new English study, published in BMC Medicine, changes in the vaginal microbiota can lead to miscarriage. These include the inflammation caused by these changes in the bacteria that would be responsible for this end of pregnancy. Thus, these “results might present a new perspective on the causes of miscarriages” underlines Dr. Karen Grewal, lead author of the study.
No abnormalities in the embryo
The Imperial College London study looked at 167 pregnant women between March 2014 and February 2019. A total of 93 women miscarried and 74 delivered at term. Among the women who made a miscarriage54 had no chromosomal abnormality in the embryo.
The vaginal microbiota prevents other bacteria
The London researchers explain, in their study, the key role of the vaginal microbiota in the fight once morest other bacteria. In effect, vaginal flora is very rich in acid-producing lactobacilli. These prevent the growth of other potentially harmful bacteria. Thus, an imbalance favors the proliferation of certain bacteria.
