Changes in the Vagina and Vulva
"Lining of the vagina before menopause (left) and after menopause (right). Before menopause, when the vagina is well supplied with estrogen, its lining is thicker and has more folds, allowing it to stretch with intercourse and childbirth. After menopause, when levels of estrogen are low, the vaginal lining is thinner and has fewer folds, which makes it less flexible."
