Estradiol is the main form of estrogen produced by the body, predominantly by the ovaries. During menopause, the ovaries stop releasing eggs and significantly reduce their production of estradiol.
In menopause, estradiol levels typically decrease to a consistently low level. While the exact range can vary among individuals and laboratories, most postmenopausal women will have estradiol levels below 10 or 20 picograms per milliliter (pg/mL).
It’s important to note that while low estradiol levels can support a diagnosis of menopause, they are not the only factor considered. Menopause is typically diagnosed after a woman has missed her periods for 12 consecutive months, and any symptoms she may be experiencing are also taken into account.
Always consult with a healthcare provider for accurate diagnosis and treatment.
