EMAS position statement: Managing women with premature ovarian failure.

INTRODUCTION: Premature ovarian failure (also known as premature menopause) is defined as menopause before the age of 40. It can be "natural" or "iatrogenic" such as after bilateral oophorectomy. It may be either primary or secondary. In the majority of cases of primary POF the cause is unknown. Chromosome abnormalities (especially X chromosome), follicle-stimulating hormone receptor gene polymorphisms, inhibin B mutations, enzyme deficiencies and autoimmune disease may be involved. Secondary POF is becoming more important as survival after treatment of malignancy through surgery, radiotherapy and chemotherapy continues to improve. AIM: To formulate a position statement on the management of premature ovarian failure.
MATERIALS AND METHODS: Literature review and consensus of expert opinion. RESULTS AND
CONCLUSIONS: Diagnosis should be confirmed with an elevated FSH greater than 40 IU/L and an estradiol level below 50 pmol/L in the absence of bilateral oophorectomy. Further assessment should include thyroid function tests, autoimmune screen for polyendocrinopathy, karyotype (less than 30 years of age) and bone mineral density. Untreated early ovarian failure increases the risk of osteoporosis, cardiovascular disease, dementia, cognitive decline and Parkinsonism. The mainstay of treatment is hormone therapy which needs to be continued until the average age of the natural menopause. With regard to fertility, while spontaneous ovulation may occur the best chance of achieving pregnancy is through donor oocyte in vitro fertilization. It is essential that women are provided with adequate information as they may find it a difficult diagnosis to accept. It is recommended that women with POF are seen in a specialist unit able to deal with their multiple needs. Copyright 2010 Elsevier Ireland Ltd. All rights reserved.
