"A women's normalvaginal pHranges between 3.8 and 4.5¹ which means the vagina is acidic. This acidity helps to keep it healthy. pH is a measure of how acidic or alkaline something is. The pH range goes from 1 which is highly acidic to pH14 which is highly alkaline. pH 7 is neutral.
Lemon juice is acidic and has a pH of 2.4, whilst household bleach is highly alkaline at 12.5. Pure water is pH 7. (Values taken from Wiki)
Note that many soaps have a pH value of 9-10 so that too thorough washing will upset the healthy acidic environment of the vagina. Many experts advise not using soap on this area, and certainly try not to get soap inside which will alter the vaginal pH. The vagina is a self-cleansing organ and all you need to do is wash away secretions trapped around the external folds.
The average pH of semen ranges from 7.2 to 7.8 which explains why sex sometimes makes a woman more prone to infections such as BV.
Blood has a pH range of from 7.34 to 7.45 which explains why menstruation can cause an attack of BV. Research has shown that menstrual blood has the effect of neutralizing the normally acidic vagina - not a desirable things for any woman prone to infections.
pH values will change as you progress through life. Pre-puberty the reading will be around pH7; during our reproductive years when the vagina is more vulnerable to infection an acidic pH of around 3.8 to 4.5 guards our health; and after menopause we return to a pH of 6-7.
Normal Saliva PH
Urine pH is used to classify urine as either a dilute acid or base solution. Seven is the point of neutrality on the pH scale. The lower the pH, the greater the acidity of a solution; the higher the pH, the greater the alkalinity. The glomerular filtrate of blood is usually acidified by the kidneys from a pH of approximately 7.4 to a pH of about 6 in the urine. Depending on the person's acid-base status, the pH of urine may range from 4.5 to 8.
saliva 6.5 - normal is 6.2 to 7.4
urine 7.0 - range is 4.5 to 8
v. 5.75 - shouldn't be above 4.5
- Low doses of an antibiotic such as trimethoprim-sulfamethoxazole (TMP/SMZ) or nitrofurantoin daily for 6 months or longer. If taken at bedtime, the drug remains in the bladder longer and may be more effective. Research has shown this therapy to be effective without causing serious side effects.
- Single dose of an antibiotic after sexual intercourse.
- A short course (1 or 2 days) of antibiotics when symptoms appear.
