Genitourinary Syndrome of Menopause: Pathophysiology, Clinical Presentation, and Differential Diagnosis.

Scientific information is incomplete regarding the genitourinary syndrome of menopause. Both the lower genital and urinary tracts are rich in receptors for reproductive hormones and are highly susceptible to waning ovarian hormones at menopause. Symptoms of dryness and pain emerge in late perimenopause, but they can also result earlier from cancer therapies or bilateral oophorectomy. Lower urinary tract symptoms rise in prevalence at midlife and increase further with advancing age. Because ovarian senescence is typically followed by years of aging, some postmenopausal complaints may be attributable to increasing longevity.
