How much does vaginal pH affect women's reproductive health?

Update Time:2023/7/31
The pH value is a numerical value used to represent the degree of acidity and alkalinity. We know that a pH value of 7 means neutral, a value lower than 7 means acidic, and a value higher than 7 means alkaline.


01  What does the pH in the vagina represent?

The estrogen secreted in the adult female body combines with the lactobacilli in the vagina to keep the pH value of the vaginal environment between 3.7 and 4.5.

Due to the special physiological composition of women, the vagina itself is a bacterial environment, and it is acidic. In this case, the female vagina has a self-cleaning function, which can effectively prevent the invasion of germs.

There are thousands of colonies living in a healthy vagina, 90% of which are Lactobacillus, which keeps the pH value of the overall environment between 3.8 and 4.5, thereby resisting and inhibiting the invasion and reproduction of pathogens, so this is called vaginal autogenesis. Self-cleaning or sterilization function.

Most women can maintain this internal stability throughout their lives. This is the result of the precise regulation of women's hormone levels, the full secretion of the vaginal endometrium, and the synergistic effect of probiotic bacteria in the vagina.

02  What does a change in pH mean?

If the PH value is 4.8, it means that the vaginal environment of this female friend is acidic, which ensures the normal self-purification of the vagina and can effectively prevent virus invasion.

When the pH value rises or falls, the internal environment is destroyed, which will cause the reproduction of other flora and white blood cells, and according to the individual's physique, other harmful flora will multiply in large numbers until the lactobacillus can no longer maintain the normal pH value environment of the vagina, and eventually The cleanliness of the vagina will deteriorate. At this time, due to external reasons, pathogenic bacteria such as Escherichia coli, Candida albicans, and Staphylococcus aureus will take the opportunity to invade the vagina, multiply in large numbers in the already destroyed PH environment, erode the inner mucous membrane, and form Infectious inflammation, such as vaginitis, cervicitis, pelvic inflammatory disease, etc.
Nearly 75 percent of all adult women will have at least one yeast infection in their lifetime. Even if they have never had sex, frail women will be recruited!

The vagina is a natural barrier for the invasion of germs. All women must pay attention to the safety of this first door. In addition to daily vulva cleaning, it is crucial to maintain the vaginal environment and pay attention to the pH value at all times.


03  Under what circumstances will the PH value change and affect women's health?

During the menstrual period or in the following days, the pH value of the vagina rises and remains at 5.0-6.5, allowing bad bacteria to multiply. Therefore, more attention should be paid to private hygiene at this time, so that the pH value can return to the normal range as soon as possible.

The pH value of male intimate skin is 5.5, and the pH value of semen is between 7.2 and 8.0. Even if everyone uses condoms, most condoms are made of rubber and sealed in a neutral environment. The lubricating oil on the outside of the condom is neutral, with a pH of 7! Coupled with exercise, it will affect the pH value of the vagina, and it is easy to send harmful bacteria into women's private parts...

Pregnancy/Lactation During pregnancy, hormones begin to change suddenly, and various body functions change accordingly. Some people are weaker and more likely to cause infections; when mothers start breastfeeding, the estrogen level is relatively low, the number of lactic acid bacteria decreases, and lead to an increase in pH.

In addition to the above common effects, of course there are more, including daily diet, personal hygiene habits, etc... Small changes in vaginal pH can be adjusted adaptively, but too high or too low will cause diseases.

04  PH value is your barometer

The vagina naturally heals, but sometimes it needs help: itching, odor, and colored discharge are its distress calls. The vaginal wall is gentle and not picky, and it absorbs indiscriminately any substance that enters the vagina. Women's health issues have always been a topic that everyone pays close attention to and is ashamed to express. Real health should start with prevention and understanding!
