Primary Ovarian Insufficiency (POI)

What is Primary Ovarian Insufficiency?

Primary Ovarian Insufficiency, or Premature Ovarian Failure, causes the ovaries to stop functioning properly much earlier than expected, typically before age 40. This causes reduced oestrogen levels and reduced egg supply. The POI does not imply that ovaries have ceased their functioning, just as in natural menopause. Occasional ovulation may still occur, indicating that one can still be pregnant.

POI may influence hormone levels, overall well-being, and fertility. There is a possibility of restoring estrogen levels in individuals with primary ovarian insufficiency. This will prevent certain conditions that may occur as a result of low estrogen, like heart disease and weak and brittle bones.

What are the types of Primary Ovarian Insufficiency?

There are various underlying mechanisms leading to the development of Primary Ovarian Insufficiency, and knowledge of its various forms can assist in guiding diagnosis and Primary Ovarian Insufficiency treatment. Although the symptoms may be very similar, the cause differs from person to person. There are four known types, which are:

• Idiopathic POI

  It is the most common one, the precise cause of which is unknown. Most people get POI without any medical, genetic or environmental precipitating factors.

• Genetic-related POI

  Some chromosomal anomalies may damage the development or functioning of the ovary, e.g. Turner syndrome or Fragile X premutation, causing early ovarian dysfunction.

• Autoimmune-related POI

  In this type, the immune system mistakenly attacks ovarian tissue. It can either be isolated or co-exist with other autoimmune disorders like thyroid or adrenal diseases.

• Iatrogenic POI

  This occurs because medical treatments that affect the ovaries can include chemotherapy, radiotherapy, or surgery.

What are the Causes of Primary Ovarian Insufficiency?

Primary Ovarian Insufficiency may result from genetic, medical, and environmental factors. The precise cause in most situations is not clear; however, various factors may contribute to ovarian failure.

Key causes include:

• Genetic conditions : Genetic defects, including Turner syndrome or the Fragile X premutation, that may impair ovarian function and development early in life.
   
• Exposure to toxins : Ovarian insufficiency due to toxins is usually caused by chemotherapy and radiotherapy. These treatments can damage DNA. Ovarian insufficiency may be accelerated by other toxins, such as cigarette smoke, chemicals, pesticides, and viruses.
   
• Autoimmune disorders : The immune system detects and kills foreign or unwanted cells that may cause infections, cancer, or other abnormalities in the body. However, sometimes the immune system loses its way and attacks normal, healthy cells of the body.
   
• Surgical removal of ovarian tissue : Therapies, particularly those involving the ovaries, such as ovarian cysts, endometriosis, or those related to the ovarian blood supply. Such interventions can lead to unwanted follicular loss or changes in ovarian activity. In some instances, such as reconstructive surgeries of the pelvis, this also results in the likelihood of long-term damage to the ovaries.

What are the Symptoms of Primary Ovarian Insufficiency?

The symptoms can be manifested slowly or abruptly. Common signs include:

• Irregular or Missed Periods: One of the most frequent and initial symptoms.
   
• Hormonal variation predisposes to hot flushes by decreasing hypothalamic activity, leading to a sudden sensation of heat.
   
• Poor vaginal health due to low estrogen levels, night sweats, and lack of sex drive, as low oestrogen cannot keep the vagina healthy.
   
• The indications of cognitive changes are mood swings and memory loss due to the disruptions of estrogen on the neurotransmitters (dopamine and serotonin).
   
• Infertility: Difficulty conceiving is a primary reason women seek a diagnosis.
   
• Sleep Disturbances: Insomnia or disrupted sleep patterns are frequently reported.

The symptoms are similar to those of early menopause, and that is why it is essential to evaluate them properly.

What are the Risk Factors and Complications of POI?

POI is not a problem that only impacts reproductive health. It is also capable of affecting the emotional, hormonal, and physical health.

Risk Factors

• Age : Although primary ovarian insufficiency can affect women of any age, its incidence rises with age. POI is more common in adult women.
   
• Family History : Women whose family history has primary ovarian insufficiency or early menopause have a high probability of developing it compared to women with no family history of POI.
   
• Genetic Conditions : Women are more susceptible to POI because of hereditary genes and genetic disorders like Turner Syndrome.

Long-Term Complications

• Osteoporosis : It is a condition in which bones become weak, fragile, and easily broken. Women who possess low amounts of oestrogen are at a greater risk of developing osteoporosis.
   
• Increased risk of heart disease : Premature ovarian insufficiency (POI) significantly increases the risk of cardiovascular disease (CVD) due to a prolonged lack of estrogen, which can lead to poor heart health outcomes.
   
• Infertility : One of the complications of primary ovarian insufficiency is not being able to conceive. In rare cases, pregnancy can be carried to the point when the body becomes exhausted of its egg supply.
   
• Emotional issues : There are those individuals with primary ovarian insufficiency who are depressed or anxious. This may be because of the threat of infertility and other diseases that can come up as a result of low levels of estrogen.

How is Primary Ovarian Insufficiency Diagnosed?

The Primary Ovarian Insufficiency diagnosis involves several steps to establish the situation and understand its effects. A physician examines menstrual cycles, symptoms, medical interventions, family history, and overall health.

1. Hormonal Blood Tests

The following tests are essential in the confirmation of POI:

• FSH (Follicle-Stimulating Hormone): Elevated levels imply the ovarian drop.
   
• Oestrogen levels in POI are normally low.
   
• AMH (Anti-Mullerian Hormone) -indicates ovarian reserve.
   
• TSH and Prolactin - Tested to eliminate thyroid or hormonal conditions.

2. Pelvic Ultrasound

Ultrasound assesses:

• Ovarian size
   
• Follicle count
   
• Uterine lining

When the antral follicles are low, it usually indicates a positive diagnosis.

3. Genetic Testing

The following tests may be conducted if POI manifests before the age of thirty or if it is suspected to be a genetic condition:

• Karyotype analysis
   
• Fragile X premutation screening

4. Autoimmune Tests

In cases of suspected autoimmune disease, specialised blood tests can be ordered. Accurate premature ovarian failure diagnosis helps develop a tailored care plan, particularly in assisted reproductive therapy.

How is Primary Ovarian Insufficiency Treated?

The management of Primary Ovarian Insufficiency aims to control symptoms, preserve a person's long-term well-being, and support fertility.

1. Hormone Replacement Therapy (HRT)

HRT aids in the replacement of the oestrogen that the ovaries cease to produce. Benefits include:

• Reducing hot flashes
   
• Supporting bone health
   
• Improving vaginal comfort
   
• Regulating menstrual cycles
   
• Reducing the long-term risk of heart disease.

It is typically prescribed until the onset of natural age (around 50 years) of the menopause.

2. Fertility Treatment Options

Natural conception may not be impossible, but it may be hard with POI. Fertility assistance can involve:

• IVF using donor eggs: This is the most effective in most cases of POI.
   
• Freezing egg or embryo, in case POI is diagnosed in time.
   
• In the case of intermittent ovarian activity, ovulation induction is required.
   
• Advanced IVF techniques, depending on the ovarian reserve and medical condition

3. Emotional Support and Counselling

POI​‍​‌‍​‍‌​‍​‌‍​‍‌ is able to affect one's mind and emotions negatively. Therefore, counselling is the most appropriate means through which such individuals can be helped to deal with their stress, grief, or anxiety, which may be caused by fertility or hormonal changes.

4. Lifestyle and Dietary Adjustments

Supportive lifestyle habits can improve overall outcomes:

• A nutritious diet containing plenty of calcium and vitamin D.
   
• Weight management
   
• Regular exercise
   
• Avoiding smoking
   
• Managing stress

5. Management of Long-Term Health Risks

This includes:

• Bone density scans
   
• Heart health assessments
   
• Regular follow-up appointments

A tailored combination of therapies provides the best results for both health and fertility.

When Should You See a Doctor?

Medical assistance is required in case of:

• No periods for 4–6 months.
   
• Abnormal, non-pregnancy cycles.
   
• At a young age, symptoms such as night sweats or hot flashes are observed.
   
• Difficulty conceiving.
   
• Fatigue, mood changes, or vaginal discomfort which is unexplained.
   
• Ovarian Insufficiency family history.

Early evaluation improves treatment options, especially for fertility preservation.
