Welcome to Menopause Research Review! Now that menopause has hit the mainstream, we’re swimming in a steady stream of studies, which is great and can also be overwhelming. So for 2025, we’re introducing a regular segment called Menopause Research Review where we break down key research as it comes out with resident reproductive endocrinologist and menopause performance specialist Dr. Carla DiGirolamo. This week we kick it off with a study published in Menopause: The range and variation in serum estradiol concentration in perimenopausal and postmenopausal women treated with transdermal estradiol in a real-world setting: a cross-sectional study. We dive into hormone testing, what it tells us (and what it doesn’t) as well as what it means (or not) to have therapeutic levels.

Carla DiGirolamo, MD, PhD, is a Double Board Certified Reproductive Endocrinologist and Obstetrician/Gynecologist specializing in infertility and menopausal medicine. She is also a Crossfit Level 1 trainer, Certified Nutrition Coach, and member of CrossFit Health.
