What Is Early Menopause?
The average age at which women typically experience menopause is around age 51. Early menopause, also referred to as premature menopause, premature ovarian failure (POF) and primary ovarian insufficiency (POI), occurs when a woman experiences menopause prior to turning age 40. It can occur as a result of genetic abnormalities that affect the ovaries, with family history playing a role; certain medical conditions can also cause early menopause.
Between 10 and 20% of women who experience early menopause have a family history of early menopause. In many other cases, it is the result of a health condition. For example, early menopause is highly associated with thyroid disease, or surgical removal of ovaries. Women who have undergone chemotherapy or radiation treatments may also experience early menopause.
At CHR, early menopause has been a major focus of research and clinical care. Early menopause is the end stage of usually a lengthy process of early premature ovarian aging (POA), a condition where a woman’s ovarian reserve depletes much earlier than is normal. Our preference, of course, is to see patients before they have reached the end stage, which is POF, because at an earlier POA stage we can still be successful with fertility treatments for women moving toward early menopause. The secret of diagnosing POA early enough is the recognition that even a relatively young woman can have diminished ovarian reserve(DOR) for her specific age group!
There are several major known causes of early menopause. The table below lists them by type of causes:
