What are premature menopause, early menopause and primary ovarian insufficiency?

Premature menopause and early menopause are conditions where a woman goes through menopause at an earlier age than is typically expected. Both conditions can result in women being unable to become pregnant. If there is no obvious medical or surgical cause for the premature menopause, this is called primary ovarian insufficiency (POI). Primary ovarian insufficiency is also referred to as premature ovarian insufficiency.

The name premature ovarian failure (POF) is no longer used because women who are told they have early menopause can have intermittent ovulation, menstrual bleeding or even pregnancy after being told they have ovarian “failure.”

What is menopause?

Menopause is a stage in a woman’s life when menstruation (periods) ends. Natural menopause typically happens when a woman is in her early 50s. This is a normal part of the aging process and means that a woman can no longer become pregnant. There are three stages to natural menopause:

  • Perimenopause: This is a transition phase where the ovaries start to make less hormones, causing fluctuating levels of estrogen and progesterone, as well as less testosterone. This stage stops when menopause begins. Menopausal symptoms tend to begin during this time and can often be the worst.
  • Menopause: In this stage, a woman’s period stops. The ovaries no longer release eggs and estrogen levels become very low. Once a woman has not had periods for 12 straight months, she has gone through menopause. However, it is important to ensure that the lack of periods is not due to another reason (like abnormal thyroid function or the use of birth control pills).
  • Postmenopause: This is the time after a woman has gone through menopause. The symptoms that happen during menopause, such as hot flashes, may start to fade away but could continue for a decade or longer in many women.

What age does a woman typically go through menopause?

Women typically go through natural menopause in their early 50s. The average age is between 51 to 52.

What is the difference between premature menopause and early menopause?

The difference between premature menopause and early menopause is when it happens. Premature menopause occurs before a woman is 40. Early menopause is when a woman undergoes menopause before age 45.

Many of the causes of premature menopause can also be causes of early menopause. The two types of menopause also share many of the same symptoms.

How common is premature menopause, early menopause and primary ovarian insufficiency?

Premature menopause happens to about 1% of women under age 40. Early menopause, occurring in women under age 45, is seen in about 5% of women.
