Understanding Progesterone: Myths, Science, and Health Impacts

Menopause Mastery Show | Understanding Progesterone: Myths, Science, and Health Impacts   Progesterone in Perimenopause & Menopause: Bioidentical vs Progestins, Sleep, Cognition, and the Real Science   Welcome to Menopause Mastery! Join Dr. Betty Murray in this episode as she breaks down the science behind progesterone.  Amid online controversy, Dr. Betty explains what progesterone does in the body, how it declines first in perimenopause, and why bioidentical micronized progesterone differs from synthetic progestins used in birth control and older HRT like Prempro.    She reviews evidence that oral micronized progesterone (often ~300 mg at bedtime) can improve sleep architecture and may reduce hot flashes/night sweats, while clarifying mixed findings and underpowered studies. It addresses brain and cognition claims by separating human data (largely neutral/no cognitive harm, mood benefits) from alarming animal studies, and explains individual variability via allopregnanolone metabolism, PMDD/depression history, genetics, and route of delivery (oral vs vaginal). In addition, she discusses cardiovascular nuance, endometrial protection with estrogen, and cyclical vs continuous dosing considerations.   If you're a woman over the age of 35, and are looking for relief from hot flashes, night sweats, and disrupted sleep, this episode is for you. Please share with other women in your life that deserve to have their symptoms taken seriously!     00:00 Progesterone Controversy 01:08 Progesterone Basics 01:55 Perimenopause Decline 03:06 Progestins vs Progesterone 06:10 Hot Flashes Evidence 09:17 Sleep and Metabolites 11:39 Cardiovascular Nuance 15:18 Brain Debate Explained 16:19 Human Studies Summary 20:09 Allopregnanolone U Curve 22:15 Animal Study Misuse 25:17 Oral vs Vaginal Routes 31:27 Cycling vs Continuous 37:47 Key Takeaways Recap 41:59 Closing and Empowerment Connect with Dr. Betty Murray:  Betty Murray Website: https://www.bettymurray.com/  Instagram: https://www.instagram.com/drbettymurray/    Links:  The Fierce Female Method for Longevity (Dr. Betty's book): https://fierce.hormoneshelp.com/  Menrva Telemedicine: https://gethormonesnow.com/     FREE Hormone Quiz: https://bit.ly/3wNJOec    Living Well Dallas: https://www.livingwelldallas.com/   Hormone Reset: https://hormonereset.net/    More from the Podcast:  Subscribe to #MenopauseMastery → https://www.youtube.com/channel/UCwONPdSvb2-YYY74VhD-XBw  YouTube Video Podcast Link: https://youtu.be/QP0v2gvLr0M Apple Podcasts → https://podcasts.apple.com/us/podcast/menopause-mastery/id1607369247    Spotify → https://open.spotify.com/show/0tNsjm32CZNXSgSFEwS3uH    Thank you for listening to Menopause Mastery.
