Why "Normal" Labs Aren't Optimized for Fertility | TSH, Ferritin, Glucose & IVF Failure
Get Pregnant Naturally
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...

The IVF Mistake That Causes Failed Cycles to Keep Repeating
Get Pregnant Naturally
If you're heading into another IVF cycle after a failed transfer, you're probably being told to trust the process and try again. But what if the process is the problem? In this episode, we get into how to tell whether your next cycle is actually different — or whether you're about to repeat the same outcome with a new protocol number. In this episode you'll learn: The three signs your last cycle wasn't fully interpreted, just failed Why changing the protocol doesn't always change the outcome What "unexplained" actually means and why it's often a gap, not a diagnosis How time pressure...

Normal Semen Analysis but IVF Still Failing? What Wasn't Tested
Get Pregnant Naturally
Failed IVF with normal sperm? You're not alone, and the answer may be in what wasn't tested. DNA fragmentation and oxidative stress don't show up on a standard semen analysis. But they can drive fertilization failure, embryo arrest, and poor blastocyst development. If the male side was cleared after the basic parameters were evaluated, it may not have been fully evaluated. In this episode, you'll learn: What a semen analysis actually measures and what it leaves out Why normal parameters don't always translate to embryo development How DNA fragmentation and oxidative stress affect...

Why a Good Embryo Doesn’t Implant in IVF (What’s Often Missed)
Get Pregnant Naturally
If your IVF transfer failed despite a good embryo, normal lining, and a smooth protocol, you may have been told it was “just bad luck.” But failed implantation with a euploid or high-quality embryo is not random. It often means key biological factors were never fully evaluated before the transfer. You followed the plan. The embryo looked good. The lining was “fine.” And it still didn’t work. This is where many people get stuck. Not because there are no answers, but because no one stepped back to assess the full picture before repeating another transfer. In this episode, we break down...

Unexplained IVF Failure What Is Being Missed Before Your Next Cycle
Get Pregnant Naturally
Unexplained IVF failure happens when a cycle doesn’t work, and no clear cause is identified, but that doesn’t mean nothing is wrong. In many cases, it means the biology behind the cycle wasn’t fully evaluated. You did everything you were told to do. The protocol looked good. The embryos developed. The lining was fine. And it still didn’t work. Then you hear the word “unexplained.” That’s where many people get stuck. Not because there are no answers, but because no one has stepped back to assess the full picture. In this episode, we break down what unexplained IVF...

Failed IVF Cycle: How to Audit What Went Wrong Before Trying Again
Get Pregnant Naturally
When an IVF cycle fails, the focus usually shifts to the next protocol. Different medications. Higher doses. Another retrieval. But an IVF cycle produces a huge amount of biological data that is rarely fully analyzed before repeating treatment. Ovarian response, egg maturity, embryo development, and the internal environment around transfer all provide important signals about what may be influencing the outcome. Yet many couples are encouraged to move forward with another cycle before those patterns are carefully reviewed. In this episode, we step back and walk through how to interpret a failed...

Why Implantation Fails: Gut Health, Inflammation and the Vaginal Microbiome
Get Pregnant Naturally
Implantation failure is often blamed on the uterus. The lining. The timing. The transfer protocol. But implantation is not something the uterus decides on its own. Implantation is an immune event that reflects what is happening across the entire body. When inflammation, gut dysfunction, or microbial imbalance is present, the immune system may not shift into the receptive state required for implantation, even when embryos appear strong and transfers are performed correctly. In this episode we step back from the narrow focus on the uterus and explore how gut health, inflammation, and the vaginal...

Why Your IVF Cycle Was Decided 90 Days Before It Started
Get Pregnant Naturally
Most couples do not walk into IVF lightly. By the time you reach a cycle, you have likely changed your diet, added supplements, tried acupuncture, adjusted your lifestyle, and done everything you were told might help. And yet, stimulation begins, and the outcome feels underwhelming. Here’s the biological reality: egg and sperm development are influenced during the 90 days before a cycle ever starts. Follicles recruited at stimulation were already developing months earlier. During that window, metabolic signaling, inflammatory load, hormonal communication, and stress physiology quietly set...

Day 3 vs Day 5 Embryo Arrest: What the Timing Really Means
Get Pregnant Naturally
Poor embryo development is not random. And “it just didn’t work” is not an explanation. If your embryos stopped growing on Day 3 or Day 5, you’ve likely been told some version of the same thing. Bad luck. Egg quality. Try again. But Day 3 vs Day 5 embryo arrest are not interchangeable events. The timing carries biological clues. And when those clues are ignored, couples often repeat cycles without addressing what actually shaped the outcome. In this episode, we break down what early arrest, later arrest, and repeating arrest patterns may be signaling and how to think more clearly...

Why Rushing Into the Next IVF Cycle Often Backfires
Get Pregnant Naturally
After a failed IVF cycle, the pressure to move quickly into the next one can feel overwhelming. Clinics often encourage momentum. Emotionally, it can feel safer to stay in motion than to pause. But rushing into another IVF cycle too quickly can quietly reinforce the same biological conditions that shaped the last outcome. If you’ve been told to increase stimulation, change protocols, or “just try again,” this episode challenges that reflex. Because before another round begins, the more important question is: What actually needs to shift in the biology? In this episode of Get Pregnant...
info_outlineWhat if your Premature Ovarian Insufficiency (POI) wasn’t just about your ovaries but about your immune system turning against them?
Most women with POI are told it’s simply early menopause. The conversation stops at hormone replacement or donor eggs. But new research shows that for many women, POI has autoimmune roots. When that’s the case, treatment, prognosis, and even pregnancy potential all look very different.
In this episode, we explore how the immune system can drive POI, the red flags most doctors miss, and which labs uncover what’s really happening inside your body. You’ll also hear how a functional fertility approach can calm immune dysfunction and support natural ovarian activity.
You’ll learn:
-
The latest evidence connecting autoimmunity and Premature Ovarian Insufficiency
-
Red flags that suggest POI may be immune-driven rather than purely ovarian
-
The key labs to request for thyroid, gut, and immune system assessment
-
Why conventional HRT isn’t enough and how bioidentical hormones fit in
-
Functional fertility strategies that support hormone balance and ovarian function
Sarah Clark is the founder of Fab Fertile Inc. and the host of Get Pregnant Naturally. Her team specializes in functional approaches for low AMH, high FSH, diminished ovarian reserve, premature ovarian insufficiency, recurrent miscarriage and helping couples prepare their bodies for pregnancy success naturally or with IVF.
This episode is for you if:
-
-
You’ve been diagnosed with POI, low AMH, or high FSH and want to understand what’s driving it
-
You or your family have autoimmune conditions like thyroid disease, celiac, type 1 diabetes, or lupus
-
You’ve had irregular cycles, miscarriages, or failed IVF transfers, and feel like something deeper is being missed
