    Vaginal Estrogen, Menopause & Hormones: What Your Doctor May Not Be Telling You

    Vaginal and urinary symptoms are common during perimenopause and menopause—but understanding why they happen and how different forms of estrogen work can be confusing. In Episode 8 of this hormone series, Dr. Brendan McCarthy breaks down the relationship between systemic estrogen, vaginal estrogen, estradiol, estriol, testosterone, and the genitourinary symptoms many women experience during menopause.

    Is Estrone Really the “Bad Estrogen”? What Your Labs Actually Mean

    An elevated estrone level can be alarming—especially when you search online and immediately find scary information about cancer, diabetes, or obesity. But does a high estrone level automatically mean something is wrong? In this episode, Dr. Brendan McCarthy, Chief Medical Officer of Protea Medical Center, takes a closer look at estrone and why it shouldn't be treated as a simple “good” or “bad” hormone. Dr. McCarthy also discusses his own evolution in understanding estrone and why he believes good medicine requires continually questioning what we think we know. The goal isn't to tell you what decision to make. It's to give you better information so you can have a more informed conversation with your healthcare provider.   📚 Download the free research resources and citations: Visit www.protealife.com for episode notes, references, and educational materials.   Dr. Brendan McCarthy is the founder and Chief Medical Officer of Protea Medical Center in Arizona.

    The Biggest Mistake Women Make When Starting Estrogen Therapy

    Should every woman take estrogen? Or should no one? According to Dr. Brendan McCarthy, both extremes miss the point. The best hormone therapy is personalized, evidence-based, and designed around the individual—not headlines or trends. In this episode, Dr. McCarthy explains why today's growing "estrogen for everyone" movement can be just as concerning as the outdated fear created by the Women's Health Initiative study. Hormone replacement therapy isn't about following the crowd—it's about understanding your body, your risks, and your long-term health goals. In this video, you'll learn: Why hormone therapy should never be one-size-fits-all The difference between individualized care and "pill mill" medicine What the Women's Health Initiative actually studied—and how it was misinterpreted Why estrogen helps with some conditions more than others The questions every woman should ask before starting hormone replacement therapy How experienced clinicians monitor hormones to keep treatment safe over time At Protea Medical Center, we believe hormone therapy should be built around you—your symptoms, your lab work, your health history, and your goals. If you're considering hormone replacement therapy, make sure you're working with a provider who takes the time to explain your options, monitor your progress, and adjust treatment as your body changes.   📚 Download the free research resources and citations: Visit www.protealife.com for episode notes, references, and educational materials.   Dr. Brendan McCarthy is the founder and Chief Medical Officer of Protea Medical Center in Arizona.

    Estrogen Isn't One Hormone: The Truth About Estradiol, Estrone & Estriol

    When someone says, "estrogen causes cancer" or "estrogen causes blood clots," what estrogen are they talking about? In this episode, Dr. Brendan McCarthy explains one of the biggest misconceptions in hormone replacement therapy (HRT): estrogen isn't a single hormone—it's a family of hormones.

You'll learn why the type of estrogen, how it's delivered (oral, patch, injection, pellet), and how it's monitored all matter. Dr. McCarthy also discusses why informed consent goes beyond signing paperwork—it means truly understanding the treatment you're receiving and why it was chosen for you. In this episode: What estradiol, estrone, and estriol actually do Why estrogen is a family—not a single hormone How oral estrogen differs from patches, injections, and pellets Why delivery method changes how your body metabolizes estrogen The difference between bioidentical, synthetic, and animal-derived estrogens Why lab timing and monitoring are essential for safe HRT The importance of true informed consent in hormone therapy Four questions every patient should ask before starting estrogen 📚 Download the free research resources and citations: Visit www.protealife.com for episode notes, references, and educational materials.   Dr. Brendan McCarthy is the founder and Chief Medical Officer of Protea Medical Center in Arizona.

    Why the Same Hormone Works Differently for Every Woman

    Why does one woman feel incredible on hormone replacement therapy while another gains weight, feels anxious, or sees no improvement at all? The answer isn't simply the hormone—it's how your body processes it. In this episode, Dr. Brendan McCarthy explains why the route of hormone delivery (oral, topical, injectable, or pellets) dramatically changes how hormones behave in the body. He also breaks down the role of liver metabolism, sex hormone-binding globulin (SHBG), body fat, inflammation, insulin resistance, and lab timing—and why these factors matter when creating an individualized hormone treatment plan. You'll learn: Why the same hormone can produce completely different results in different women How oral, topical, injectable, and pellet hormones affect your body differently Why "normal" lab results don't always mean your hormones are optimized The importance of free testosterone vs. total testosterone How inflammation, body fat, and liver function influence hormone metabolism Four questions every woman should ask her hormone provider Why hormone therapy requires ongoing monitoring—not just a prescription Hormone replacement therapy is never just about writing a prescription.
