Primary ovarian insufficiency (POI) affects about 3.7% of women in the world. Getting the diagnosis can feel lonely and scary. Many women are left asking, ‘What is POI and what does it mean for me?’
The main thing to know is that POI can’t be reversed, but it can be managed. More women are having kids later in life. Because of this, learning the risk factors and early signs of POI can make a real difference. Maybe you’re dealing with irregular periods or just want to understand your body better. We have the details you need to know.
Key Takeaways
- POI (Primary Ovarian Insufficiency) happens when your ovaries stop working normally before 40.
- It can lead to hormone changes, declined ovarian function, and fertility problems.
- The cause for POI is mostly unknown, but genes, autoimmune issues, and treatments like chemo may be common culprits.
- The most common symptom of POI is irregular periods.
- You can still get pregnant with POI — naturally or with help.
- There’s no cure for POI, but there are ways to take care of your body and manage your symptoms..
What Is Primary Ovarian Insufficiency?
Primary ovarian insufficiency has other names, like premature ovarian failure or early menopause. It means your ovaries don’t work the way they should before you turn 40. This can cause you to have fewer eggs, lead to hormone changes, or give you irregular cycles. It’s a type of ovarian dysfunction (a problem with how the ovaries work) that can cause lower estrogen and fertility issues.
Why the age 40 cutoff? Most women start menopause around age 50, so when these changes happen before 40, it’s not typical. Less than 2% of women naturally go through menopause this early. That’s why doctors use this age as a guideline for premature ovarian insufficiency. It helps them identify women under 40 who are at a higher risk for these issues.
What Causes Primary Ovarian Insufficiency?
Sometimes doctors know why POI happens, but a lot of the time they don’t. In about 67% of cases, the reason is unexplained. But here are some known causes, including different health conditions:
- Genetic conditions or chromosomal differences, like Turner syndrome or Fragile X premutation
- Family history — you might have a higher chance if your mom or sister had early menopause
- Autoimmune issues — this is when your immune system gets confused and attacks your own cells
- Medical treatments like chemo or radiation, especially when you’re young
- Surgery that removes both ovaries
- Environmental factors, which are things in the world around you — this can include heavy metals, cigarette smoke, and some plastics or makeup
- Other health conditions like hypothyroidism, type 1 diabetes, Sjogren’s syndrome, or alopecia
Many of these things also cause low ovarian reserve. This means you have fewer healthy eggs than expected. The main problem is usually damage to the ovaries or a fast drop in the number of eggs. This can be caused by genetics, medical treatments, or autoimmune issues.
That’s why finding the reason for the problem, if possible, is so important. It helps you handle the condition and look at your choices for fertility and your long-term health. You can think of it like your ovaries are having problems earlier than usual (POI is a form of early ovarian failure).
Symptoms of Primary Ovarian Insufficiency
POI can be confusing because the symptoms can come and go. The symptoms happen because your body is making less of the hormone estrogen.
The most common sign is a change in your period. And it can be one of the first signs that you’re not ovulating regularly. Your periods might become irregular. They could be much longer or shorter, or even stop completely. These ovulation disorders are a main reason for low estrogen in your 30s and an important sign of possible ovarian failure.
Here are some other symptoms you might notice:
- Hot flashes and night sweats
- Vaginal dryness or pain during sex
- Vaginal irritation — like burning, itching, peeing more often, or leaking a little pee
- Low sex drive
- Mood changes — like feeling worried, sad, angry, or easily annoyed
- Trouble getting pregnant (infertility issues)
- Trouble sleeping or focusing
- Osteoporosis (weaker bones) or risk of heart disease if it’s not treated
All of these are primary ovarian insufficiency symptoms. It’s important to pay attention if you are in your 20s or 30s. Look for these ovarian failure symptoms or signs of irregular menstrual periods. These can also be signs of early menopause.
When Should You See a Doctor?
You should talk to your doctor if you’re under 40 and your menstrual cycle has been irregular or missing for three months or more. You should also call them if you see signs of low estrogen — the signs could be hot flashes, night sweats, vaginal dryness, mood swings, or trouble focusing.
Having difficulty getting pregnant for no clear reason is another big sign to see a doctor. You should get checked out sooner if you have a family history of early menopause. The same is true if your family has autoimmune conditions or genetic syndromes. All of these can be signs of POI or premature ovarian insufficiency.
How Is POI Diagnosed?
To figure out if you have POI, your doctor will start by asking some questions. They’ll ask about your symptoms and your period history. They’ll also ask about past cancer treatments and your family’s health conditions. You’ll also get a physical exam to check out what’s going on with your body.
Understanding your hormone levels
You’ll have blood tests to check your hormone levels. The doctor will look closely at two hormones: follicle-stimulating hormone (FSH) and estrogen. A high FSH level and a low estrogen level are strong signs of POI. They usually do these tests more than once just to be sure.

Getting a clearer picture with an ultrasound
Your doctor might also do an ultrasound. This lets them look at your ovaries to see if they still have follicles. Follicles are the tiny sacs that hold your eggs. If the ultrasound shows very few or no follicles, it can mean you have a reduced ovarian reserve (you have fewer eggs left).
Looking at the ultrasound and your hormone levels helps the doctor understand your ovarian function — or how well your ovaries are working. Sometimes, they might do genetic or autoimmune tests to figure out why it’s happening.
How Is POI Treated?
The main goal of primary ovarian insufficiency treatments is to help with POI symptoms. They also help protect you from long-term health risks that come with low estrogen and premature ovarian insufficiency, like osteoporosis. The right treatment for you will depend on your symptoms and your goals. This is especially true if you want to get pregnant, which might mean using fertility medications.
Estrogen and progesterone therapy
These treatments replace the hormones your body is missing. This can help with things like hot flashes and vaginal dryness. And it also helps protect your bones and heart. Your doctor might tell you to take calcium and vitamin D or do weight-bearing exercises, like walking, to help keep your bones strong.
Fertility treatments
If you want to have a baby, treatments like IVF or using donor eggs can be options. Your doctor can talk to you about these different primary ovarian insufficiency treatments. There are also medications that can help with hormone balance.
Emotional support
Having good people you can trust in your life is very important. Talking to a therapist or joining a support group can make a big difference in how you feel.
Is Primary Ovarian Insufficiency the Same As Premature Menopause?
No, they’re not exactly the same. With premature menopause, your periods stop completely before you are 40 — meaning pregnancy usually isn’t possible. Premature menopause can be caused by your family history, health problems, pelvic surgery, chemotherapy, or radiation.
POI is different. Even though doctors often don’t know the cause of POI, the main difference is that your ovaries still work a little. With POI, your ovarian function is hard to predict, but it’s not totally gone. You might still ovulate sometimes or get occasional periods — and there may still be a small chance to get pregnant.
Can You Still Get Pregnant With Primary Ovarian Insufficiency?
Yes, it’s still possible to get pregnant with POI. About 5-10% of women with the condition get pregnant naturally. Ovarian function can be unpredictable — working on and off — so ovulation might still happen sometimes. It’s why experts changed the name from premature ovarian failure to primary ovarian insufficiency — your ovaries haven’t failed completely
POI often means you have a low ovarian reserve (you have fewer eggs left than other people your age). But having fewer eggs doesn’t mean you have zero eggs. You can still release an egg during ovulation and get pregnant
With help from treatments like ovulation meds or IVF, your chances may be even better. Since your periods can be irregular with POI, knowing when you ovulate is key. This is where a fertility monitor like Inito can help. By tracking your fertility hormones to find your fertile window, you can make sure you don’t miss a chance to conceive. Inito also tracks PdG (a urine metabolite of progesterone) to confirm if you’re actually ovulating.
Can I Reverse Primary Ovarian Insufficiency?
You may not be able to completely fix or reverse primary ovarian insufficiency. This is especially true if the cause is genetic or if doctors don’t know the reason. But you can do things to support your reproductive health as you get closer to this natural age.
How to manage POI
Staying away from harmful chemicals, eating a balanced diet, getting regular exercise, and managing stress can all help. Try eating healthy foods that fight inflammation in your body (an anti-inflammatory diet). And add in gentle exercises like yoga or walking. Getting into a good sleep habit is another step toward managing premature ovarian failure naturally.
These steps might not bring your full ovarian function back. But they can help improve your hormone and egg health and how you feel all around. When you focus on what you can control, it can help your chances of pregnancy and help you feel more in control.
Talk to your doctor if you want more support or want to learn more about your treatment choices. Ask them about primary ovarian insufficiency medication, or consider talking to a fertility specialist. These providers are experts who understand ovarian failure symptoms and ovulation disorders. The more you know about what POI is, the more confident you will feel in handling your health.
