Get Pregnant Naturally: How To Solve Your Infertility Problems Using Functional Medicine

Your TSH is "normal." Your ferritin is "normal." Your glucose is "normal." And IVF still isn't working. Here's why normal lab ranges were never built for fertility and what optimal actually looks like. Most reference ranges are designed to flag disease in the general population, not to optimize egg quality, embryo competence, or implantation. That gap is where a lot of unexplained IVF failure, embryo arrest, and recurrent loss live. In this episode, Sarah Clark walks through the four biomarker categories most often dismissed as "fine" but influence cycle outcomes in women with diminished ovarian reserve, low AMH, high FSH, and failed transfers. What you'll learn: - What "normal" lab ranges actually measure and what they miss - Why fertility-optimized TSH sits closer to 1–2 mIU/L, not 4.0 - Ferritin 80–100 ng/mL and what it means for egg energy and endometrial development - Fasting glucose under 86, insulin stability, and follicular development - Why hsCRP under 1 mg/L matters for implantation and embryo quali
