“Isn’t estrogen dangerous?”
I hear this from women all the time. Their ovaries stopped at 34, or came out at 41, and they either feel guilty for taking estrogen or quietly go without it.
Here is what nobody explained: the scary hormone headlines came from studies of mostly older women, average age about 63. The Menopause Society says those results do not apply to women with premature or early menopause. When your ovaries stop 5 to 20 years early, estrogen is not an extra. It is a replacement for a hormone your body was built to have until about 50.
“You can’t change when your ovaries stopped. You can change what happens next.”Dr. Amy Killen, MD

Premature ovarian insufficiency, early menopause, and surgical menopause, with the common causes your doctor should look for.
Why it matters
What the research shows about the heart, brain, bones and lifespan when estrogen leaves early and is not replaced.

Replace it, symptoms or not, until at least 50 to 52. Plus the POI dose table: patch, gel, oral estradiol and progesterone.
Surgical menopause is different
When both ovaries come out, estrogen, progesterone and testosterone drop abruptly. What to ask about.
