The main objective of this study is to assess whether the presence of abnormal vaginal flora (intermediate flora or vaginosis) is a risk factor for vaginal lesions at the time of delivery. For this, the primary endpoint will be the proportion of vaginal lesions according to the presence or absence of abnormal vaginal flora.

A more precise qualitative and quantitative study of vaginal flora isolated from pregnant women and its association with vaginal lesions will also be conducted.
