D)Low estrogen levels

Question

Quizplus · Accepted Answer

At puberty the pH becomes more acidic (4 to 5) and the squamous epithelial lining thickens. Both defenses are greatest when estrogen levels are high and the vagina contains a normal population of Lactobacillus acidophilus, a harmless resident bacterium that helps maintain pH at acidic levels. Any condition that causes vaginal pH to rise, such as douching or use of vaginal sprays or deodorants, low estrogen levels, or destruction of L. acidophilus by antibiotics, lowers vaginal defenses against infection.
