Vaginal microbiome may play key role in pregnancy health and preterm birth risk, researchers say

Researchers reviewed evidence linking the vaginal microbiome to pregnancy health and spontaneous preterm birth, highlighting how Lactobacillus-dominated communities help maintain immune balance and vaginal acidity. Dysbiosis and inflammatory signaling may contribute to preterm birth risk, while emerging microbiome-targeted therapies aim to restore protective microbial ecosystems.
