Over 33 million U.S. women will transition through menopause in the next decade. Among women with natural menopause, the transition typically lasts four years, with a mean age at menopause of 51 years. Menstrual irregularity (90%) and vasomotor symptoms (VMS) (80%) are the most common symptoms associated with the transition. Hormone therapy has been the gold standard for treating VMS symptoms against which other therapies are measured. However, resistance to hormone therapy use due to its risks and side effects continues to fuel the search for safer alternatives.
