Why do estradiol levels vary among women using hormone therapy?

September 24, 2019

CLEVELAND, Ohio (September 24, 2019)--The benefits of hormone therapy (HT) on atherosclerosis relates to achieved estradiol levels among those women who initiate HT early in postmenopause. Despite the use of hormones, however, women's estradiol levels are often inconsistent. A new study identifies the various determinants of estradiol levels among healthy women using HT. Study results will be presented during The North American Menopause Society (NAMS) Annual Meeting in Chicago, September 25 to 28, 2019.

The researchers involved in the new study relied on analysis of data from the Early versus Late Intervention Trial with Estradiol (ELITE). Their work in this area previously showed that estradiol levels were higher among early compared to late postmenopausal women. The new research focused on identifying the various factors affecting estradiol levels and how this impacted a woman's risk of developing atherosclerosis (hardening of the arteries).

The research yielded a number of results. Higher estradiol levels were associated with such determinants as higher BMI, higher weight, higher creatinine, and antihypertensive medication use, among others. Current and past smoking and use of antifungal medicine were associated with lower estradiol levels. These determinants were similar between early and late postmenopausal women.

"Healthcare providers need to consider the impact of these various factors when attempting to reach desirable estradiol levels in their postmenopausal patients and understand that not all women's bodies will respond the same to hormone therapy," says Dr. Intira Sriprasert, lead author of the study from the Keck School of Medicine of the University of Southern California.

"NAMS continues to promote individualized approaches to treating women's menopause symptoms, and this study provides one more piece of evidence as to why such individualization is critical," says Dr. Stephanie Faubion, NAMS medical director.

There are few musical moments more well-worn than the first four notes of Beethoven's Fifth Symphony. But in this short, we find out that Beethoven might have made a last-ditch effort to keep his music from ever feeling familiar, to keep pushing his listeners to a kind of psychological limit. Big thanks to our Brooklyn Philharmonic musicians: Deborah Buck and Suzy Perelman on violin, Arash Amini on cello, and Ah Ling Neu on viola. And check out The First Four Notes, Matthew Guerrieri's book on Beethoven's Fifth. Support Radiolab today at Radiolab.org/donate.
