What is the normal range of vaginal pH?

The normal vaginal pH range for reproductive-aged women (age 15- 49) who have menstrual period is 3.8-4.5. https://www.healthline.com/health/womens-health/vaginal-ph-balance

Why is vaginal pH important?

An acidic vaginal pH is protective. It makes the vaginal environment harder for the growth of unhealthy bacteria and yeast to cause infection.

When the vaginal pH is higher than 4.5, it provides a better environment for unhealthy bacteria or yeast to grow. It puts you at risk for vaginal infections, like bacterial vaginosis (BV) or trichomoniasis (trich).

A slightly acidic vagina usually doesn’t cause disease. But too much of a good thing can be harmful.

If the vaginal acidity rises too much, it may cause acid burn, which damages the vaginal lining cells. The condition is called "cytolytic vaginosis" or CV. Cytolytic means cell damages. Discomforts include vaginal burning and discharge.

Too much acidity may also reduce your fertility. Sperm likes an alkaline environment. The optimal pH for them to swim is 7.0 - 8.5.

During sex, the pH level inside the vagina temporarily rises, shifting the normally acidic vagina more alkaline to protect sperms so that they can swim to the egg. Acidic environment affects the mobility of sperms, reducing the chance of fertility.



The normal pH for women after menopause is higher than 4.5. Postmenopausal women (age >49) no longer have menstrual period and their estrogen level reduces. The normal vaginal pH is about 5.3 (mean)

If you are postmenopausal, a higher vaginal pH does not necessarily suggest an infection when you do not have symptoms like odor or discharge. You may experience discomforts like burning, itching, and painful sex, but these symptoms may not be caused by infections. They may be associated with normal aging like vaginal atrophy and dryness caused by estrogen reduction.

Hormones like estrogen can relieve these aging related symptoms, but hormones have a cancer risk if used for a long term.

NeuEve can help women to relieve these discomforts safely without hormones. In fact, it works better than hormones. To date, it has helped over 100,000 women with the most severe vaginal atrophy that hormones had failed to find relief.
