Healthy vaginal pH is typically quite acidic, with a pH value of around 4. However, the alkaline pH of semen can neutralize vaginal pH. One potential class of microbicides acts by reducing the pH of vaginal secretions, which may kill (or otherwise inactivate) pathogenic microorganisms. One such agent is BufferGel, a spermicidal and microbicidal ...
This test involves putting a drop of fluid obtained from the vagina onto paper strips containing nitrazine dye. The strips change color depending on the pH of the fluid. The strips will turn blue if the pH is greater than 6.0. A blue strip means it's more likely the membranes have ruptured. This test, however, can produce false positives.
To control bacterial growth, the vagina is normally slightly acidic with a pH of 3.8–4.2. A swab of the discharge is put onto litmus paper to check its acidity. A pH greater than 4.5 is considered alkaline and is suggestive of bacterial vaginosis.
Vaginal discharge is not always present in yeast infections, but when occurring it is typically odorless, thick, white, and clumpy. [28] Vaginal itching is the most common symptom of candida vulvovaginitis. [28] Women may also experience burning, soreness, irritation, pain during urination, or pain during sex. [30]
PH Scale showing 3.8-4.5 in the acidic range. The vaginal environment is slightly acidic, with pH ranging from 3.8 - 4.5 based on multiple factors such as age, natural bacteria, and stage of menstrual cycle. [4] Due to the variety in possible pH values, this poses an interesting consideration for drug delivery.
The vaginal pH of macaques also differs, with near-neutral to slightly alkaline median values and is widely variable, which may be due to its lack of lactobacilli in the vaginal flora. [256] This is one reason why, although macaques are used for studying HIV transmission and testing microbicides , [ 256 ] animal models are not often used in the ...
“Lube is used to increase comfort of vaginal or anal sex,” explains Dr. Sophocles. ... Best Value Lube: K-Y Ultragel ... The gentle pH-balanced formula is free from glycerin and parabens and ...
Although the lactic acid produced by lactobacilli contributes to the vaginal acidity, it is still not proven to be the primary source of low vaginal pH, but the fact remains that most lactobacilli thrive best at a pH < 3.5 . [13] [14] [15] Normal vaginal pH is considered to be under 4.5 with a range of 3.8 to 4.4. [5]
