Premature Menopause and POI Differences

What are some premature menopause and POI differences?

In Primary Ovarian Insufficiency: Symptoms & Causes – Overview the (United States) Mayo Clinic note:

“Sometimes, primary ovarian insufficiency is confused with premature menopause. But they aren’t the same. People with primary ovarian insufficiency can have irregular or occasional periods for years. They might even get pregnant. But people with premature menopause stop having periods and can’t become pregnant”.4

In Primary Ovarian Insufficiency: Summary – What Is Primary Ovarian Insufficiency (POI)? the (United States) MedlinePlus explain:

“POI is different from premature menopause. With premature menopause, your periods stop before age 40. You can no longer get pregnant. The cause can be natural or it can be a disease, surgery, chemotherapy, or radiation. With POI, some women still have occasional periods. They may even get pregnant. In most cases of POI, the cause is unknown”.5

In Premature Menopause the (United States) Menopause Society’s (formerly the North American Menopause Society) definition is:

“The normal age range of menopause is between 46 and 55 years However, about three in 100 women will go through menopause before age 40. This is known as premature menopause”.6

Yes and no. In Premature and Early Menopause: Symptoms of Premature & Early Menopause the JH explain:

“Symptoms of premature and early menopause are like those you would experience if you reached menopause at the expected age of 51 to 52 years, but symptoms can often be more severe due to the sudden change in hormone levels”.8
