As women age, the body’s natural production of estrogen hormonal levels
decreases usually starting between the ages of 45 – 55. Menopause is a natural
stage in the aging process, which signifies the end of menstrual periods and a major
shift in hormone levels. The natural aging process, in addition to surgical removal of
the ovaries commonly lowers the levels of estrogen commonly referred to as “Pre-
menopause”, “Peri-menopause” or “Menopause”. Progesterone hormone
replacement primarily balances estrogen.
