Understanding Primary Ovarian Insufficiency (POI)

At a Glance

Primary Ovarian Insufficiency (POI) occurs when the ovaries stop functioning before age 40. Because it causes a sudden loss of essential hormones, physiological hormone replacement therapy (HRT) is the standard of care to relieve symptoms and protect long-term heart, bone, and brain health.

A diagnosis of Primary Ovarian Insufficiency (POI) — often referred to as premature menopause — can be overwhelming. Being told your ovaries have stopped functioning normally before the age of 40 brings a wave of medical and emotional challenges. It is not just about losing your period; it is about managing a sudden drop in hormones that protect your heart, bones, and brain [1].

This guide is designed to empower you with the evidence-based knowledge you need to advocate for yourself. POI is a systemic condition that requires a completely different approach to care than natural, age-related menopause.

Common questions in this guide

What is Primary Ovarian Insufficiency (POI)?
Primary Ovarian Insufficiency, sometimes called premature menopause, occurs when a woman's ovaries stop functioning normally before age 40. This causes a significant drop in estrogen and other hormones that normally protect heart, bone, and brain health.
Why do I need Hormone Replacement Therapy (HRT) for POI?
Physiological HRT is the standard of care for young women with POI because it replaces the hormones your body would naturally produce at your age. This helps relieve symptoms and protects you from the long-term health risks of early estrogen loss.
Can I still get pregnant if I have POI?
While POI causes severe infertility, there is still a 5-10% chance of spontaneous pregnancy. If you are trying to build a family, consulting a reproductive endocrinologist can help you explore your fertility preservation and family building options.
What causes premature menopause?
POI can be caused by genetic factors like FMR1 premutations or autoimmune conditions, though sometimes the cause is unknown. Identifying the specific cause is a critical part of your diagnosis to help guide your future healthcare and family planning.
