Q

(Inflammation of Vagina)

1-2. Epithelium is stratified squamous - under estrogen stimulation it proliferates and matures increasing its resistance to infection due to what two things?

A
  1. Thickening of keratinized epithelium
  2. Local production of lactic acid from glycogen deposited under the epithelium therefore lowers pH increasing resistance to bacterial infection
