Vaginal pH and Sexuality

Vaginal pH correlates with the level of estrogens in the vaginal tissue, the composition of the vaginal ecosystem, the vulnerability to colonization from colonic saprophytic germs. Factors that may modulate the vaginal ecosystem include Sexually Trasmitted Diseases (STD), inappropriate hygiene habits, hormonal status, iatrogenic conditions. As estrogens modulate both the level of vaginal pH and quality of genital arousal in women, expressed by vaginal congestion and lubrication, pH could be a biological marker of vaginal sexual responsiveness.
