“Loss of ovarian function occurring in women younger than 40 years of age is called premature ovarian insufficiency (POI). POI may also be referred to as…”.1

Umbrella

What may the Premature Ovarian Insufficiency (POI) Umbrella include?

Depending on the Source (DotS) this umbrella may include:

  • Premature Ovarian Failure (POF)
  • Premature Ovarian Insufficiency (POI)
  • Primary Ovarian Insufficiency (POI)

Definition

What is primary ovarian insufficiency (POI)?

DotS the definition of POI may vary. In Primary Ovarian Insufficiency: Symptoms & Causes – Overview the (United States) Mayo Clinic’s definition, dated 20 October 2023, is:

“Primary ovarian insufficiency occurs when the ovaries stop working as they should before age 40. When this happens, the ovaries don’t make the typical amounts of the hormone estrogen or release eggs regularly. The condition often leads to infertility. Another name for primary ovarian insufficiency is premature ovarian insufficiency. It also used to be called premature ovarian failure, but this term isn’t used anymore”.2

Premature Menopause

Is premature menopause the same as POI?

In Primary Ovarian Insufficiency: Symptoms & Causes – Overview the Mayo Clinic also 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”.3

POI Common or Not

How common is POI?

In Premature Ovarian Insufficiency: How Common Is Premature Ovarian Insufficiency? You and Your Hormones, the (United States) Society for Endocrinology elaborate on:

“It is relatively uncommon, occurring in one in 1,000 women under the age of 30 years and 1-4% of women under the age of 40 years. Early menopause (less than 45 years) occurs in up to 12% of women”.4

POI and Periods

Can women with POI have periods?

In Menopause Before 40 and Spontaneous Premature Ovarian Insufficiency the Australasian Menopause Society (AMS) note:

“Women with spontaneous POI have irregular or no periods”.5

POI and Pregnancy

Can women with POI become pregnant?

In Premature and Early Menopause: What Causes Premature and Early Menopause? POI and Fertility the (Australian) Jean Hailes for Women’s Health explain:

“If you have been diagnosed with POI and do not want to become pregnant, you should use contraception. Many women are unable to conceive a baby naturally after POI; however, there is a one in 50 chance of a spontaneous pregnancy”.6

POI and Menopausal Symptoms

Can women with POI have menopausal symptoms?

In Menopause Before 40 and Spontaneous Premature Ovarian Insufficiency the AMS note:

“Women may or may not have menopausal symptoms such as hot flushes”.7

POI Symptoms

What may be POI symptoms?

In Premature Ovarian Insufficiency (POI): Summary – What Are the Symptoms of Primary Ovarian Insufficiency (POI)? according to the (United States) Medline Plus:

“The first sign of POI is usually irregular or missed periods. Later symptoms may be similar to those of natural menopause:

  • Hot flashes
  • Night sweats
  • Irritability
  • Poor concentration
  • Decreased sex drive
  • Pain during sex
  • Vaginal dryness

For many women with POI, trouble getting pregnant or infertility is the reason they go to their health care provider”.8

Hormone Therapy

For women with POI, what is one of the recommendations about hormone therapy of the Joint Position Statement By the British Menopause Society, Royal College of Obstetricians and Gynaecologists and Society for Endocrinology on Best Practice Recommendations for the Care of Women Experiencing the Menopause?

On page two in the Joint Position Statement By the British Menopause Society, Royal College of Obstetricians and Gynaecologists and Society for Endocrinology on Best Practice Recommendations for the Care of Women Experiencing the Menopause, first published online 10 June 2022, one of the recommendations is:

“Women with POI and early menopause (40–45 years old) should be advised that HRT is unlikely to increase risk of breast cancer in younger menopausal women under the age of 50. The meta-analysis by the Collaborative Group on Hormonal Factors in Breast Cancer in 2019 reported that the use of HRT in postmenopausal women younger than 50 increases the risk of breast cancer diagnosis which contradicts previous evidence and advice to date. However, the control group, of age-matched postmenopausal women was inappropriate as an early menopause reduces breast cancer risk. Current recommendations are that the risk of breast cancer in relation to the years of HRT exposure in women with POI/early menopause should be counted from the average age of natural menopause (from the age 50 years)”.9

What is another recommendation of the Joint Position Statement?

On page four in the Joint Position Statement another recommendation is:

“Women with POI and early menopause (40–45 years old) should be advised to take hormone replacement at least until the average age of the menopause”.10

Chronic Disease

Is there an association between POI and chronic disease?

In Optimising Health After Early Menopause: Summary, published 05 March 2024, a paper included in The Lancet: Series From the Lancet Journal – Menopause 2024 also published on 05 March 2024, the authors note:

“Both early menopause and premature ovarian insufficiency can herald an increased risk of chronic disease, including osteoporosis and cardiovascular disease”.11

Early Menopause: Women’s Experiences

What is the (Australian) Healthtalk Australia’s Early Menopause: Women’s Experiences?

In Early Menopause: Women’s Experiences – Overview Healthtalk Australia elaborate on:

“On this unique site you can read, watch and listen to stories of 30 women aged between 28 and 51 years, from diverse socio-cultural backgrounds living in Victoria, Australia, who have shared what it is like to experience early menopause (EM).

Women talked about being diagnosed with spontaneous early menopause, premature ovarian insufficiency (POI), medically-induced early menopause, or menopausal symptoms as a result of cancer and/or other medical treatments”.12

Health Care Provider

What if I think I have POI?

If you think you have POI it may be in your best interest to choose to talk to your health care provider about this.

In Primary Ovarian Insufficiency: Symptoms – When To See A Doctor the (United States) Mayo Clinic elaborate on:

“If you’ve missed your period for three months or more, see your health care team to figure out the cause. You can miss your period for many reasons, such as pregnancy, stress, or a change in diet or exercise habits. But it’s best to get a health care checkup whenever your menstrual cycle changes.

Even if you don’t mind not having periods, see a health care professional to find out what’s causing the change. Low estrogen levels can lead to a condition that causes weak and brittle bones, called osteoporosis. Low levels of estrogen also can lead to heart disease”.13

In Primary Ovarian Insufficiency: Treatment & Therapies the Endocrine Society explain:

“Treatment depends on whether you have symptoms or are at risk for serious health problems. Hormone therapy (HT) is the most common treatment. HT combines estrogen and progesterone, another sex hormone. HT relieves menopausal symptoms and also helps prevent osteoporosis. HT can be taken as a pill or applied to your skin as a patch. Vaginal rings can also supply estrogen to the body”.14
