Estrogen--and vaginal moisturizers--generally lower the pH level, making it a more healthy environment. The vagina is typically slightly acidic, like tomatoes or wine. The loss of estrogen with menopause can throw off our pH levels, reducing circulation and lubrication. Being able to generate enough moisture is part of what allows our vaginas to reregulate pH level after intercourse, when semen, which is more alkaline, is temporarily disruptive.
