Menopause

Menopause refers to the time in a woman’s life when she stops having a menstrual period and is no longer fertile. The time leading up to menopause is called the menopausal transition, or perimenopause. Typically, menopause occurs between ages 45 and 55.

NICHD is one of many federal agencies and NIH Institutes working to better understand menopause. NICHD also supports and conducts research on conditions related to menopause, such as osteoporosis and menopausal hormone therapy.
