menopause

Menopause is the phase that marks the end of a woman’s reproductive cycle and occurs at an average age of 52 in the United States. Menstrual cycles permanently cease to occur, and ovarian follicles no longer mature. Clinically, menopause is marked by high levels of the hormone FSH and is associated with hot flashes, osteoporosis, and heart disease.
