Medical News Today confirms that the typical pH level of the vagina ranges between 3.8 and 5.

According to The Mirror, Dr. Vanessa MacKay, a spokesperson for the Royal College of Obstetricians and Gynaecologists, explains, “The vagina has a self-cleaning mechanism through natural secretions. It contains beneficial bacteria that serve to protect it.”

Dr. MacKay further elaborates that any disruption to this natural balance can potentially result in infections like bacterial vaginosis or thrush. As well as inflammation. She emphasizes that it is entirely normal and healthy for a woman to produce a clear or white discharge from her vagina. Reinforcing the importance of understanding and accepting these natural bodily functions.
