Expert opinion by the Italian Society of Gynecology of the Third Age (SIGiTE) and the Italian Society of Menopause (SIM) on diagnosis and treatment of premature ovarian insufficiency.

Premature ovarian insufficiency (POI) is a critical condition affecting young women before the median age of menopause and consisting of spontaneous oligo-amenorrhea for at least four months associated with follicle stimulating hormone (FSH) levels ≥25 UI/L detected before 40 years of age. Several causes like genetic abnormalities, autoimmune diseases, drugs and/or pelvic surgery may favor this condition that is associated with a deeper clinical impact on women's health compared to physiological menopause. Specifically, cardiovascular and musculoskeletal systems as well as brain could be especially affected by the early loss of ovarian hormones. Therefore, appropriate treatment is necessary to adequately narrow the biological gap with the average age of menopause. Hormone replacement therapy (HRT) is the treatment of choice, regardless of the presence of neurovegetative symptoms. Transdermal high dosage of natural estradiol is generally preferred to guarantee the preservation of cardio-metabolic and bone health. When contraception is required, oral estroprogestins (EPs) maybe considered. A referral to reproductive experts for fertility preservation techniques should be considered case by case.
