NCT ID NCT06866119

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This observational study will follow 45 women with primary ovarian insufficiency (POI)—a condition that causes early menopause—who are starting estrogen replacement therapy. Researchers will measure heart health markers before and after 6 months of treatment and compare them to healthy women without POI. The goal is to see if estrogen therapy improves blood vessel function and other metabolic signs related to heart disease.

Active substance

estrogen replacement therapy (transdermal 17beta-estradiol and progesterone)

What this could lead to

If successful, this could provide stronger evidence that estrogen therapy helps protect the heart in women with early menopause.

What could go wrong

This is a small observational study (45 participants) that does not test a new treatment—it only measures existing therapy effects. Results may not apply to all women with POI.
