What is the normal vaginal pH?

The normal vaginal pH typically ranges from 3.8 to 4.5, with an average around 4.5. This acidity is crucial for maintaining a healthy vaginal environment, helping to prevent infections by inhibiting the growth of harmful bacteria and maintaining the balance of the vaginal flora, predominantly lactobacilli, which contribute to that acidic environment.

A pH of 4.5 indicates that the environment is slightly acidic, which is ideal for promoting vaginal health. Values lower than this could suggest an overly acidic environment, while higher pH values might indicate potential disturbances, such as bacterial vaginosis or other infections.

Having a clearer understanding of the normal range of vaginal pH can assist in recognizing when assessment may be needed for different gynecological conditions.
