Anatomy and physiology of Vagina to prevent infection

चित्र
In adult female ,vagina is lined by stratified squamous epithelium.In newborn female,it is lined by transitional epithelium.squamous epithelium is resistant to gonococcal infection.Thus , gonococal vaginitis cannot occur in adult female. Vagina has local inhabitant bacteria called Doderlein's bacillus Which breaks down the glycogen present in vaginal epithelium into lactic acid resulting in acidic pH(4-5.5, average 4.5) of vagina.The acidic pH of vagina acts as a barrier for external organism and protect from infection. Physiological vaginal discharge..... Clear, white and flocculent odourless discharge. Smear contains epithelial cells, lactobacillus pH ranges from 3.8 to 4.2 pH increase with increased oestrogen States:in pregnancy,OCP,mid-cycle,PCOS or premenarchal If pH increase in primenopausal woman, investigation for other effects of excess oestrogen.
