Bioidentical Hormones Explained: Testosterone, Progesterone, Estrogen & How to Use Them Safely | Episode 27

Listen Later

In this episode of The Hormone Café, Dr. Sarah Pederson breaks down bioidentical hormones—what they actually are, how they differ from synthetic hormones, and how they’re used safely and effectively in clinical practice. She walks through testosterone, progesterone, estrogen, and DHEA, explaining how each hormone functions in the body, the best delivery methods, and why dosing, timing, and personalization matter so much.

Rather than using hormones as a “band-aid,” Dr. Sarah emphasizes a root-cause, physiology-first approach—supporting the body while working toward long-term balance and eventual weaning when appropriate.

In This Episode, You’ll Learn:

🌱 What “Bioidentical” Really Means

Bioidentical hormones have the same molecular structure as the hormones your body naturally produces.
Dr. Sarah explains the key hormones used in practice:

  • Testosterone
  • Progesterone
  • Estrogen (estradiol, estrone, estriol)
  • DHEA (adrenal hormone and precursor)

    • These hormones are used to support—not override—natural physiology.

    🔥 Testosterone in Women: Why It Matters

    Testosterone isn’t just for men. Women need it for:

    • Libido
    • Energy and motivation
    • Muscle mass and recovery
    • Healing and metabolism
    • Egg quality and follicle stability

      • Dr. Sarah explains why daily, low-dose testosterone is preferred over pellets or injections, how it supports fertility, and why the goal is always eventual weaning—not lifelong use.

      💊 Best Absorption Methods for Testosterone

      • Troches (dissolved between cheek and gum)
      • Topical creams

        • Oral testosterone is avoided to protect gut and liver health and ensure steady absorption.

        🌸 Progesterone: Timing Is Everything

        Progesterone is only made after ovulation.
        Dr. Sarah explains:

        • Why checking progesterone at the wrong time leads to misdiagnosis
        • Why progesterone taken too early can inhibit ovulation
        • The danger of “cycle day 21” testing for everyone

          • Progesterone should always support the natural cycle—not disrupt it.

          🩸 When Progesterone Is Helpful

          Progesterone may be used when:

          • You’re not ovulating at all
          • You have irregular or absent cycles
          • You have a luteal phase defect
          • Progesterone is low after ovulation
          • Supporting early pregnancy

            • Dr. Sarah outlines how cyclic progesterone can help retrain the body to ovulate and cycle regularly.

            🌙 How Progesterone Is Given

            • Oral (most common; taken at night due to drowsiness)
            • Vaginal (more uterine-focused, less blood absorption)
            • Patch or cream (typically for peri/postmenopause)
            • Injections (sometimes necessary in pregnancy)

              • If progesterone makes you feel worse, the dose or delivery method needs adjusting—there’s no “powering through.”

              🧠 Estrogen: Not Too High, Not Too Low

              Estrogen is produced daily and plays a critical role in:

              • Ovulation
              • Cycle length
              • Energy and cognition
              • Uterine lining health
              • Pregnancy support

                • Dr. Sarah explains why estrogen must be tested before and after ovulation and how low estrogen is often misdiagnosed as PCOS.

                📈 When & How Bioidentical Estrogen Is Used

                Estrogen may be used when levels are truly low and root causes are addressed simultaneously.
                Delivery options include:

                • Oral estradiol (micro-dosed and carefully titrated)
                • Vaginal estrogen (for dryness, UTIs, cervical mucus, microbiome support)
                • Patches (helpful in perimenopause or when oral estrogen isn’t tolerated)

                  • The goal is always physiologic balance—never excess.

                  🌊 Perimenopause, Menopause & Hormone Smoothing

                  During perimenopause, estrogen can swing dramatically.
                  Low-dose daily estrogen (often via patch) can:

                  • Smooth hormone fluctuations
                  • Reduce brain fog, mood swings, headaches
                  • Improve sleep and energy

                    • Dr. Sarah emphasizes that hormone therapy should always have a plan—support, stabilize, then wean.

                    🧬 DHEA: The Precursor Hormone

                    DHEA supports:

                    • Estrogen and testosterone production
                    • Adrenal health and stress resilience
                    • Fertility and pregnancy support

                      • It can be used orally or vaginally depending on goals and symptoms.

                      📊 Root Cause Always Comes First

                      Hormones are never used in isolation. Dr. Sarah reviews:

                      • Nutrition and adequate calorie intake
                      • Stress and cortisol balance
                      • Thyroid and adrenal health
                      • Gut absorption and metabolism

                        • Hormones support healing—they don’t replace it.

                        Key Takeaways:
                        • Bioidentical hormones match your body’s natural hormones
                        • Dose, timing, and delivery method matter
                        • Hormones should make you feel better, never worse
                        • Testing must match physiology and cycle timing
                        • Root causes must always be addressed
                        • Every hormone plan needs an end game
                          • Resources & Next Steps:

                          If you’re struggling with hormone symptoms, fertility challenges, or perimenopause and want a personalized, physiology-based approach, support is available.
