Is progesterone the most misunderstood hormone in women's health?

For decades, women have been told that progesterone is only necessary to protect the uterus. But what if that's only a small part of the story?

In this fascinating and thought-provoking episode of The Girlfriend Doctor Show, Dr. Anna Cabeca welcomes renowned OB-GYN and integrative medicine pioneer Dr. Felice Gersh for a deep dive into the science, controversy, and clinical nuances of progesterone therapy in menopause.

Drawing on more than 45 years of clinical experience, Dr. Gersh explains why she believes progesterone is far more than a hormone for pregnancy and uterine protection. Together, she and Dr. Anna explore progesterone's role in brain health, inflammation, metabolism, cardiovascular wellness, sleep, cognition, and healthy aging.

They discuss why hormone therapy should never be one-size-fits-all, the differences between progesterone and synthetic progestins, the growing evidence supporting cyclic hormone therapy, and how delivery methods—including oral, vaginal, transdermal, and rectal progesterone—can produce dramatically different effects in the body.

The conversation also tackles one of the most controversial topics in women's health: hormone therapy after breast cancer.

In this episode, you'll learn:

• Why progesterone is a "life hormone," not just a reproductive hormone • The surprising neuroprotective effects of progesterone • How oral progesterone differs from vaginal and transdermal delivery • Why cyclic hormone therapy may more closely mimic natural physiology • The role of allopregnanolone in sleep, mood, cognition, and brain health • How inflammation influences breast cancer risk more than many women realize • Why individualized hormone therapy remains essential for optimal aging

If you've ever wondered whether you're using progesterone correctly—or if you've been told you don't need it after menopause—this episode may completely change how you think about hormone health.
