Considering trying a fertility lubricant, but confused by the information about pH levels? Dust off your old high school chemistry book; let’s do a refresh on what pH is in the first place!
Dust off your old high school chemistry book; let’s do a refresh on what pH is in the first place. pH is a scale, from zero to 14, used to specify the acidity or alkalinity of a water-based environment. A lower number is more acidic (think: orange juice, which has a pH of around 3.5). Substances with a high pH, like bleach, which has a pH of 13, are alkaline. In the middle, there is pure water, which has a pH of seven and is considered “neutral” because it has neither acidic nor basic qualities. A pH greater than seven is considered “basic.”
A healthy vagina is somewhat acidic
A healthy vagina is moist and somewhat acidic, with a pH between 3.8 and 4.5. But the pH of semen ranges from 5.2 to 8.2. Does it matter that they are different? Nope! The body is amazing. When sperm (which are slightly alkaline) enter the vagina, it raises the vagina’s pH, temporarily neutralizing vaginal acidity. This makes the vagina and cervix more hospitable to sperm, allowing sperm a better shot at meeting the egg.
Why a basic vagina is bad
The acidic pH of the vagina is a good thing. The vaginal microbiome has “good” bacteria called Lactobacilli, which help protect women against sexually transmitted diseases and other infections.
