The vaginal flora in most healthy women is dominated by Lactobacillus species. The absence of Lactobacillus species in vaginal flora might lead to a series of symptoms, especially in pregnant women causing adverse pregnancy outcomes, such as preterm delivery. This review focuses on the progress in the research of the relationship between vaginal Lactobacillus and preterm delivery, providing reference for the reduction of the incidence of preterm delivery.
