Primary Ovarian Insufficiency
(POF, Premature Ovarian Failure, POI)
What is primary ovarian insufficiency (POI)?
Health care providers use the term POI when a woman's ovaries stop working normally before she is 40 years of age.1,2

For many women with POI, trouble getting pregnant or infertility is the first symptom they experience and is what leads them to visit their health care provider. This is sometimes called
"occult" (hidden) or early POI.6
