Primary Ovarian Insufficiency

Irregular periods can be a sign that something is wrong. In some cases, women may feel relieved about not experiencing their period and may attribute their missed period to stress. For some, though, irregular periods can be an indication of primary ovarian insufficiency (POI), which eventually leads to infertility in most women.

Although the cause of POI remains unknown, approximately 10% of POI cases can be attributed to either a genetic condition or autoimmunity, a type of disorder that causes the immune system to attack the body's own tissues.


Because their ovaries are not functioning properly in POI, the body stops stop releasing eggs regularly and decreases the production of estrogen and other hormones. Similar to menopause, side effects of POI can include bone mass loss, but it can often be treated with hormone replacement therapy (HRT), such as an estrogen patch. Women can take a simple blood test for levels of follicle stimulating hormone (FSH) to find out if they have POI.


Adjusting your lifestyle and seeking herbal supplements to balance hormones continues to be the best approach for treating irregular periods and other symptoms of menopause. If you are worried about the infrequency of your periods, or if bleeding or spotting occurs after intercourse, you should discuss your symptoms with your doctor.
