A thorough, intimate hygiene is crucial both as a daily practice and to prevent irritating vaginitis, which causes itching or infections and may develop into phlogosis. The vagina is known to have an acid pH ranging from 3.5 to 4.2. This value may increase or decrease by one point during menstruation, pregnancy and menopause. Ph balance is due mainly to lactobacillus, which controls germs or pathogenic fungi in vaginal mucouses. When these germs prevail over lactobacillus for any reason (i.e., poor hygiene), the vaginal environment loses its balance. As a result, its acid pH turns alkaline, which is favourable to pathogenic microorganisms.
