Premature Ovarian Insufficiency (POI)
Medically reviewed by the SEDU Clinical Review Board. Detailed pathophysiology, symptoms, and care guidelines.
Clinical Overview
Loss of normal function of the ovaries before age 40, resulting in low estrogen production and lack of regular ovulation.
Associated Symptoms
- Irregular Menstrual Cycles
- Vasomotor Hot Flashes
Treatment Pathways
- Hormone Replacement Therapy (HRT)
- Lifestyle & Anti-Inflammatory Diet
Causes & Mechanisms
Follicular depletion or dysfunction linked to genetic anomalies (e.g. Fragile X premutation, Turner syndrome variants), autoimmune oophoritis, or chemotherapy.
Risk Factors
Diagnosis & Screening
Elevated follicle-stimulating hormone (FSH) levels in the menopausal range (above 40 mIU/mL) on two separate tests at least 4 weeks apart, before age 40.
Prevention & Care Guidelines
Hormone replacement therapy (HRT) maintained until the natural age of menopause (~51) to prevent osteoporosis and cardiovascular disease.
Frequently Asked Questions
Q:Is POI the same as early menopause?
Not quite. With POI, there is a small chance (~5-10%) of spontaneous ovulation and pregnancy, whereas menopause is permanent follicle depletion.
