Vaginal dryness affects any age but it most commonly occurs after menopause. In fact, up to 40 percent of postmenopausal women complain about this problem, but only a few get medical help. During the stage of menopause, the body stops producing estrogen, the hormone in charge of lubricating the vagina, maintaining its elasticity, and keeping it healthy. At first, vaginal dryness may not seem like a big deal. But over time, it can take a toll on your relationship and sex life.
