Disease category
Primary ovarian insufficiency (POI) is a condition characterized by the normal decline of ovarian function before the age of 40; unlike premature menopause, intermittent menstruation or the possibility of pregnancy may remain.
Core mechanism
The cause is usually unidentified, but genetic disorders, autoimmune diseases, anticancer chemotherapy/radiation therapy, metabolic diseases, and some toxic exposures may be involved.
Main causes · related factors
The core dysfunction is the premature depletion or improper functioning of follicles, which affects follicular growth, maturation, and ovarian hormone production.
Representative patterns
Representative manifestations include irregular or ceased menstruation, difficulty with pregnancy, hot flashes, night sweats, vaginal dryness, dyspareunia, decreased libido, and decreased concentration.
Individual differences
Family history, specific genetic changes such as Turner syndrome or Fragile X syndrome, autoimmune diseases, certain viral infections, and cancer treatments can increase the risk, and individual causes and progressions vary.
Diagnosis
Symptoms may begin with changes in menstruation and may become similar to menopause over time; infertility, osteoporosis, cardiovascular disease, hypothyroidism, ocular surface disease, and risks of anxiety/depression may accompany these conditions.
Management
Diagnosis is determined by comprehensively evaluating medical and family history, confirming pregnancy status, physical examination, hormone blood tests, and, if necessary, chromosomal analysis and pelvic ultrasound.
Treatment/Research Status
Since intermittent menstruation or the possibility of ovulation may remain, judgment should not be made based on a single menstrual pattern alone; other causes such as pregnancy, thyroid disease, and autoimmune disease must also be evaluated.
Read Evidence
Management aims to alleviate symptoms and reduce long-term health risks, with individual assessments of hormone status, bone and cardiovascular health, mental health, and comorbidities.
Key Precautions
There is no established treatment to normally restore current ovarian function; when appropriate, menopause hormone therapy is used for symptom management and risk management related to hormone deficiency.

At a Glance

Primary ovarian insufficiency (POI) is a condition characterized by the normal decline of ovarian function before the age of 40; unlike premature menopause, intermittent menstruation or the possibility of pregnancy may remain.

Representative manifestations include irregular or ceased menstruation, difficulty with pregnancy, hot flashes, night sweats, vaginal dryness, dyspareunia, decreased libido, and decreased concentration.

How the disease works

The cause is usually unidentified, but genetic disorders, autoimmune diseases, anticancer chemotherapy/radiation therapy, metabolic diseases, and some toxic exposures may be involved.

The core dysfunction is the premature depletion or improper functioning of follicles, which affects follicular growth, maturation, and ovarian hormone production.

Variations in presentation among individuals

Family history, specific genetic changes such as Turner syndrome or Fragile X syndrome, autoimmune diseases, certain viral infections, and cancer treatments can increase the risk, and individual causes and progressions vary.

The broad framework of diagnosis and management

Symptoms may begin with changes in menstruation and may become similar to menopause over time; infertility, osteoporosis, cardiovascular disease, hypothyroidism, ocular surface disease, and risks of anxiety/depression may accompany these conditions.

Diagnosis is determined by comprehensively evaluating medical and family history, confirming pregnancy status, physical examination, hormone blood tests, and, if necessary, chromosomal analysis and pelvic ultrasound.

Current status of treatment

Since intermittent menstruation or the possibility of ovulation may remain, judgment should not be made based on a single menstrual pattern alone; other causes such as pregnancy, thyroid disease, and autoimmune disease must also be evaluated.

Management aims to alleviate symptoms and reduce long-term health risks, with individual assessments of hormone status, bone and cardiovascular health, mental health, and comorbidities.

There is no established treatment to normally restore current ovarian function; when appropriate, menopause hormone therapy is used for symptom management and risk management related to hormone deficiency.

How to read clinical trials

Follow-up monitoring includes menstruation, vasomotor symptoms, bone health, cardiovascular risk, thyroid/autoimmune comorbidities, and mental health. Clinical trials must be interpreted by distinguishing between the study design (registered vs. observational) and the disclosure of results.

Points to verify during clinical consultations

In clinical care, menstrual changes and the timing of symptom onset, pregnancy plans, family history/genetic diseases, autoimmune diseases, cancer treatment/medication/exposure history, bone and cardiovascular risks, and the need for emotional support are assessed.
