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 pushes couples into decisions that don't serve them
The specific questions to ask before you commit to another cycle
I'm Sarah Clark, founder of Fab Fertile and host of Get Pregnant Naturally, a podcast with over 1 million downloads. My team works with couples navigating low AMH and failed IVF, reviewing functional lab results including gut microbiome, food sensitivity, vaginal microbiome, nutrigenomics, HTMA, DUTCH, toxin testing, and bloodwork, alongside nervous system work, to help identify patterns that may not have been considered. We work alongside your medical team, not instead of them.

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 fertilization and blastocyst outcomes
The patterns we see in recurrent IVF failure when male factor hasn't been fully assessed
Why embryo development is a shared biological process, not an egg quality issue

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 why embryo quality alone does not determine implantation and what is often missed when a transfer fails.
In this episode, you'll learn:
Why a good embryo does not guarantee implantation
The three biological layers that influence whether implantation happens
How uterine environment, hormone timing, and systemic health interact
What subtle inflammation and thyroid patterns can do to implantation
What to review before transferring another embryo
I'm Sarah Clark, founder of Fab Fertile and host of Get Pregnant Naturally. For over a decade, my team and I have reviewed hundreds of low AMH and failed IVF cases using functional testing alongside conventional fertility care. We specialize in helping couples identify the physiological patterns driving poor outcomes so decisions are grounded in interpretation, not guesswork.
If you've been moving from cycle to cycle without a clear way to evaluate what's actually been addressed, I created a free resource called the Embryo Audit Checklist. It helps you organize past cycles and labs so you can see what's been looked at and what may not have been considered yet. Access it here.

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 failure means and why repeating another cycle without deeper analysis often leads to the same outcome.
We walk through the patterns that don't show up on a standard IVF summary but still influence embryo development and implantation.
If you've been told to try again but feel like something is being missed, this will help you start asking better questions before your next step.
In this episode, you'll learn:
Why "unexplained" IVF failure often reflects a gap in interpretation, not a lack of information
The three patterns that are commonly overlooked before repeating a cycle
What to look at beyond embryo grading and lining thickness
How to think about your next step without defaulting to another round
Why clarity matters more than changing protocols

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 IVF cycle from a systems perspective so the next decision is based on biology, not momentum.
In this episode, you'll learn:
• Why a failed IVF cycle contains important biological clues that often go unexamined • What a true IVF cycle audit should include before repeating a protocol • The patterns in ovarian response, egg maturity, and embryo development that may reveal underlying imbalances • Why embryo development reflects whole body physiology, not just the laboratory environment • How to decide whether repeating a cycle makes sense or whether a different approach should be considered
