Vulvovaginal atrophy affects around 90% of postmenopausal women who may present with symptoms such as dryness, irritation, itching, burning, and dyspareunia that negatively affect the quality of life. Topical estrogen is recommended for the treatment of vulvovaginal atrophy in postmenopausal women and the FDA approved it. But it may increase the risk of breast and endometrial cancer. The oxytocin hormone also promotes positive social behavior, stress regulation, and female sexual arousal. Many previous studies show that topical oxytocin is useful for reducing vaginal atrophy in postmenopausal women.
