- Is post-menopausal (a demonstration of total cessation of menses for ≥ 1 year from the date of screening visit). A follicle stimulating hormone (FSH) level will be performed to confirm a post-menopausal state. For this study FSH levels ≥ 40mIU/mL are consistent with menopause. If a subject is on estrogen replacement and menopausal status is questionable, estrogen replacement should be discontinued for 2 weeks and then the subject rescreened, as estrogen replacement can suppress FSH.
