The numbers are in — forecasters predict 1.1 billion women worldwide will experience menopause in 2025. In the U.S., more than 1 million women reach menopause each year, and more than 75 percent of these women are employed during menopause transition years. Research conducted by the National Institute on Aging indicates menopausal hormone therapy (MHT) reduced the severity of menopause symptoms while elevating mood, sexual function, cardiovascular and brain health.
