Relation between vaginal and endocervical pH in pre- and post-menopausal women.

We aimed to verify whether vaginal fornix pH is related to endocervical pH and whether or not acid pH could contribute to the prophylactic treatment of vaginal infections. Four groups of healthy women with or without uterus were selected: pre-menopausal (>39 years) and post-menopausal (<61 years). Pre-menopausal non-hysterectomized women were further analysed in proliferative (8-12 days) and secretory phase (18-22 days) of the menstrual cycle.
