Management can normally be based on menopausal symptoms together with menstrual irregularity. Whilst a high FSH (>30 IU/ℓ) is diagnostic, lower levels do not necessarily exclude ovarian failure and therefore FSH should not be measured routinely. However, following hysterectomy, with conservation of ovaries, some women may experience asymptomatic ovarian failure. In these women, checking FSH levels can be helpful.
FSH levels are not used to determine efficacy of HRT.
