what fsh level indicates menopause
Low levels of estradiol, a form of estrogen, can indicate that your ovaries are starting to fail. When estradiol levels are below 30, it may signal that you are in menopause. However, the most important test used to diagnose premature menopause is a blood test that measures follicle stimulating hormone (FSH). FSH causes your ovaries to produce estrogen. When your ovaries slow down their production of estrogen, your levels of FSH increase. When your FSH levels rise above 40 mIU/mL, it usually indicates that you are in menopause.
