pH-balanced products have a similar acidity to a specific part of the body. Lubricants marketed as “pH balanced” often have a pH of 3.5-4.5, which is generally in the same range as a healthy vagina. pH-balanced lubricants can help to limit the occurrence of yeast infections and urinary tract infections for women who are susceptible to these conditions.

Fertility experts often recommend pH-balanced lubricants to couples who are trying to conceive, as properly balanced lubricants may not negatively affect sperm.
