PH value of the vagina
The pH value of the vagina corresponds to the secretion that is continuously produced by the vaginal mucosa.The special thing about the vagina is that the pH value of the vaginal secretion can change. It is subject to fluctuations in the hormone balance of the woman. In a menstruating woman, the pH value is ideally between 3.8 and 4.4 on the pH scale.
The acidic pH value in the vagina is caused by lactobacilli present there. These germs occur naturally in the vagina and produce lactic acid. The lactic acid and the resulting acidic environment provide the vagina with natural protection against infections and irritations. If the pH value becomes significantly more basic, this weakens the defense mechanism and bacteria can spread more easily. Due to an increased pH-value in the vagina, vaginal fungi (Candida albicans) can easily grow there.
PH value of the sperm
The sperm has a pH value of 7.2 to 7.8. The seminal fluid is more alkaline than acidic. The vagina has an acidic pH of 3.8 to 4.4 on the pH scale. Sperm need an alkaline environment to be able to move around in the vagina.
PH value of the saliva
With neutral values around 7, the pH value of saliva is ideal for fulfilling its functions. These include, for example, the digestion of carbohydrates on their way to the stomach and the remineralization of tooth enamel after diet-related acid attacks. After stimulation by food intake, the pH value in saliva rises to 7.2.
At rest, between meals, the pH value can drop to values between 6.5 and 6.9. A normal pH value is about 7 to 7.1. The pH value is also influenced by the bacterial colonization of the mouth.
PH value in the stomach
The stomach contains gastric juice, which contains large amounts of gastric acid. Stomach acid is particularly rich in hydrochloric acid. The pH value in the stomach is between 1.0 and 1.5, i.e. in a strongly acidic environment.
During the intake of food, the pH value rises to values between 2 and 4. Due to the high content of gastric acid, the pH value in the stomach remains basically acidic. Increased acidity in the stomach can cause unpleasant symptoms such as reflux/heatburning.
