Hormones maintain vaginal acidity, promote healthy lactobacilli growth, and enable the vagina to fight infection.

“I think of hormones like fluid. So, as you lose the hormones or the hormones go too high or too low, it dries everything out. The hormones keep the tissue acidic. It grows the healthy lactobacilli. It is uh the vagina is supposed to be acidic. It's supposed to be able to fight infection. And without proper hormones, you lose that ability to fight infection.”
