Brief summary: The aim of the study is to evaluate the safety and efficacy of the vaginal gel with HMW HA in women with genitourinary syndromes due to either menopause or other causes such as the patients after ovarian or breast cancer diagnosis and treatment.

Detailed description: It was recognized that GSM is likely to be underdiagnosed and undertreated9. The North American Menopause Society (NAMS) issued the treatment guideline of GSM in 2014 and encouraged the physicians and nurses to pursue menopausal women to check if they have genitourinary syndrome. GSM is considered a progressive condition in menopausal women, and the primary goal of treatment strategy is symptom relief. Options include lifestyle changes, non-hormonal, and hormonal treatments. Hormonal therapies include both topical and systemic approaches. However, many women reported that substantial concerns about the long-term safety of hormonal products.The patients are aware of the possible relationship between cancer, heart disease, stroke, and estrogen-based treatments10. For considering long-term treatment strategy, estrogen free products of vaginal lubricant or vaginal moisturizer are recommended as first line treatment for those with mild to moderate syndrome.
