Been Trying to Conceive With Normal Test Results? Here Is What May Not Have Been Looked At.
She had been trying to conceive for two years. Every test her GP ran came back normal. Her gynaecologist told her to keep trying. Nobody had ever looked at what was actually happening inside her hormonal system across the full cycle.
This is one of the most common presentations I see at Wave. A woman in her early 30s with cycles that look regular on paper but feel anything but. Significant premenstrual symptoms in the two weeks before her period. Poor sleep. Low energy. And a growing sense that something is off that nobody in the system has been able to validate or explain.
If this sounds familiar, the problem is not that nothing is wrong. The problem is that the testing being offered is not designed to find what is actually driving the issue.
What standard fertility testing looks for
Standard fertility workups typically include a day 21 progesterone blood draw, a basic hormone panel covering FSH, LH, and oestradiol, an AMH level to assess ovarian reserve, a thyroid screen, and in some cases an ultrasound. These are useful investigations and they are genuinely good at ruling out specific conditions like premature ovarian insufficiency, PCOS on an ultrasound, and significant thyroid disease.
What they are not designed to do is assess the full hormonal picture across the whole cycle, investigate how hormones are being metabolised and cleared, evaluate the metabolic environment that determines egg quality and implantation capacity, or examine the gut-hormone connection that influences oestrogen balance in ways that never show up on a blood panel.
When everything comes back normal in a standard workup, patients are frequently told to keep trying or referred directly to IVF. What is missing in between is a thorough investigation of the functional drivers that can be identified, modified, and addressed.
What standard testing consistently misses
A single day 21 progesterone draw
Day 21 progesterone gives one data point from one day of the cycle. It does not show whether progesterone is sustained across the full luteal phase or whether it is sufficient to support implantation across the days that matter most.
Hormone levels without hormone metabolites
Standard blood panels show how much hormone is in circulation. They do not show how those hormones are being broken down and cleared. Oestrogen metabolites, particularly the ratio of 2-OH to 4-OH oestrogen, have direct implications for implantation and immune activation.
Insulin resistance at subclinical levels
Standard fasting glucose can look completely normal while fasting insulin is already elevated enough to drive androgen production, impair ovulation quality, and disrupt the hormonal environment required for conception. Insulin is rarely tested in a standard fertility workup.
The gut-hormone connection
Gut dysbiosis directly affects oestrogen metabolism through beta-glucuronidase activity and the estrobolome. This is one of the most significant and consistently missed drivers of oestrogen dominance and hormonal imbalance in women trying to conceive — and it is invisible to standard fertility blood panels.
Thyroid conversion beyond TSH
TSH can be normal while free T3 is insufficient, thyroid antibodies are elevated, or T4 to T3 conversion is impaired. All of these affect the hormonal environment required for ovulation, implantation, and early pregnancy maintenance — and none of them show on a TSH-only screen.
Nutrient status relevant to fertility
Folate, B12, iron, zinc, selenium, vitamin D, CoQ10, and omega-3 fatty acids all directly influence egg quality, implantation, and early foetal development. Deficiencies at a functional level are common and consistently missed by standard pathology reference ranges.
What a functional fertility investigation looks for
At Wave Functional Health we approach fertility challenges the same way we approach every complex health presentation, by asking what the full biological picture is actually showing, not just whether individual markers fall within a reference range.
There are four areas we consistently find are either not investigated at all or investigated incompletely in patients who have been told their fertility tests are normal.
The full hormonal picture across the whole cycle
DUTCH complete hormone testing maps sex hormones, their metabolites, and the cortisol rhythm across the full day. This reveals whether progesterone is sustained through the luteal phase, how oestrogen is being metabolised, and whether the stress system is suppressing sex hormone production.
The metabolic environment driving hormonal disruption
Fasting insulin and HbA1c at functional thresholds identify subclinical insulin resistance before it appears on a standard glucose test. Elevated insulin directly suppresses ovulation quality, drives androgen production, and impairs the uterine environment for implantation.
The gut microbiome and oestrogen clearance
GI MAP stool testing assesses beta-glucuronidase activity, gut microbiome balance, and intestinal permeability — all of which directly influence how oestrogen is processed and cleared. A dysbiotic gut recirculates oestrogen rather than excreting it, driving oestrogen dominance patterns invisible to blood testing.
Nutrient status at a functional level
OptimalDX blood chemistry assesses folate, B12, iron, zinc, selenium, vitamin D, and inflammatory markers at functional reference ranges rather than disease thresholds. These nutrients directly influence egg quality, implantation capacity, and early pregnancy maintenance.
The gut-hormone connection most clinics never investigate
One of the most consistently missed drivers of hormonal imbalance in women trying to conceive is the relationship between gut health and oestrogen metabolism. A subset of gut bacteria produce an enzyme called beta-glucuronidase. When this enzyme is elevated (which is common in gut dysbiosis) it breaks down the packaging that the liver has placed around processed oestrogen before it can be excreted, and allows it to be reabsorbed into circulation.
The result is elevated circulating oestrogen, a disrupted oestrogen-to-progesterone ratio, and an inflammatory hormonal environment that directly impairs implantation. This pattern does not show up on any standard fertility blood panel. It is only visible through functional stool testing.
The gut also influences oestrogen through the estrobolome; the collection of gut bacteria responsible for oestrogen metabolism. When the estrobolome is disrupted by dysbiosis, antibiotic use, or poor dietary diversity, oestrogen clearance becomes impaired regardless of what the hormone blood tests show.

← Scroll to see full table
| Test | What it reveals for fertility |
|---|---|
| DUTCH Complete | Full sex hormone and cortisol picture across the cycle including progesterone across the luteal phase, oestrogen metabolite pathways, and the stress system impact on sex hormone production |
| Full Thyroid Panel | TSH, free T3, free T4, reverse T3, TPO and thyroglobulin antibodies — thyroid function directly influences ovulation, implantation, and early pregnancy. TSH alone is insufficient for fertility assessment. |
| Fasting Insulin and HbA1c | Subclinical insulin resistance at a functional threshold — elevated fasting insulin impairs ovulation quality, drives androgen production, and disrupts the uterine environment before glucose becomes abnormal |
| GI MAP Stool Analysis | Beta-glucuronidase activity, gut microbiome balance, and intestinal permeability — identifies gut-driven oestrogen recirculation and the dysbiosis patterns that impair hormonal clearance and drive oestrogen dominance |
| OptimalDX Blood Chemistry | Folate, B12, iron, ferritin, zinc, selenium, vitamin D, and inflammatory markers at functional reference ranges — all directly relevant to egg quality, implantation capacity, and early foetal development |
| HRV Analysis | Autonomic nervous system function and stress physiology — chronic HPA axis activation suppresses sex hormone production via pregnenolone steal and directly impairs the hormonal environment required for conception |
| Inflammatory markers | hsCRP, homocysteine, and ESR — systemic inflammation impairs implantation and egg quality and is a modifiable driver of unexplained subfertility that standard panels routinely miss at functional thresholds |
What this looks like in practice
In a recent patient at Wave, a woman in her early 30s had been trying to conceive for two years with a normal standard fertility workup. When we ran a comprehensive functional investigation three things stood out immediately.
Her DUTCH complete hormone test showed severely low progesterone in the luteal phase — the phase of the cycle where progesterone needs to be high enough to support implantation. Her day 21 blood draw had looked normal but the full hormonal picture across the cycle told a completely different story.
Her oestrogen metabolites were skewed toward the 4-OH pathway, the more inflammatory oestrogen metabolite, which is associated with immune activation and implantation difficulty.
And her fasting insulin was at 13. She had no obvious signs of insulin resistance, but at a functional level elevated insulin drives androgen production, disrupts ovulation quality, and directly impairs the hormonal environment required for conception.
Her GI MAP also showed elevated beta-glucuronidase… her gut was driving her hormonal imbalance in a way that was completely invisible to the standard fertility workup she had been given.
None of this is obscure medicine. None of it required unusual testing. It required looking at the full hormonal picture across the whole cycle and asking what the gut and metabolic environment were doing to her hormones.
What you can do
A functional medicine approach to fertility is not a replacement for reproductive medicine or specialist care. It is an investigation into the modifiable biological drivers that standard fertility workups are not designed to detect.
For many women the most important thing is not more IVF cycles or more rounds of clomiphene. It is understanding why the hormonal environment is not supporting conception and addressing those drivers directly before or alongside any assisted reproduction.
The earlier these factors are identified and addressed, the better the conditions for natural conception or for improving the outcomes of assisted reproduction where that pathway is appropriate.
Map the full hormonal picture with DUTCH
DUTCH complete hormone testing gives us sex hormones, their metabolites, and the full cortisol curve — revealing whether progesterone is sustained through the luteal phase and how oestrogen is being processed and cleared.
Assess metabolic health at a functional threshold
Fasting insulin and HbA1c identify subclinical insulin resistance before glucose becomes abnormal — one of the most modifiable drivers of ovulation quality and uterine environment.
Investigate the gut-hormone axis
GI MAP stool testing identifies beta-glucuronidase activity and dysbiosis patterns that drive oestrogen recirculation and dominance — a significant and consistently overlooked driver of hormonal imbalance in subfertility.
Identify nutrient deficiencies at functional levels
Folate, B12, iron, zinc, selenium, and vitamin D are assessed at functional reference ranges — deficiencies at this level directly affect egg quality and implantation capacity even when standard panels look normal.
Address the full thyroid picture
A full thyroid panel including free T3, reverse T3, and antibodies identifies conversion problems and autoimmune thyroid activity that directly affect ovulation, implantation, and early pregnancy maintenance.
Build and monitor a targeted protocol
Treatment is built around what the testing shows — not a generic fertility supplement plan. Progress is monitored through retesting and clinical reassessment throughout the protocol.
Frequently asked questions
A normal result on a standard fertility panel means the testing did not find anything outside its reference range — not that nothing is there to find. Standard fertility testing is designed to identify specific conditions. It is not designed to assess the full hormonal picture across the cycle, evaluate how hormones are being metabolised and cleared, or investigate the metabolic and gut drivers of hormonal imbalance.
Many of the most common functional drivers of subfertility are simply not visible to standard blood panels, which is why normal results and ongoing difficulty conceiving so frequently occur together.
Yes, significantly. The gut directly influences oestrogen metabolism through the estrobolome — the collection of gut bacteria responsible for oestrogen processing and clearance. When gut dysbiosis is present, elevated beta-glucuronidase activity allows packaged oestrogen to be broken down and reabsorbed rather than excreted, driving oestrogen dominance patterns that impair ovulation and implantation.
The gut also influences systemic inflammation, nutrient absorption, and immune regulation — all of which have direct implications for fertility. This connection is not assessed in any standard fertility workup.
DUTCH stands for Dried Urine Test for Comprehensive Hormones. It maps sex hormones and their metabolites, the full cortisol curve, and melatonin across a 24-hour period using dried urine collected at multiple time points.
For fertility specifically, the DUTCH test reveals whether progesterone is sustained through the luteal phase rather than just present at a single point in time, how oestrogen is being broken down and whether the more inflammatory metabolite pathways are elevated, and whether the stress system is suppressing sex hormone production via the pregnenolone steal mechanism. None of this is visible on a standard blood panel.
Yes. Fasting glucose can appear completely normal while fasting insulin is already elevated enough to drive androgen production, impair ovulation quality, and disrupt the uterine environment. Insulin resistance develops years before glucose becomes abnormal, and in that window it is actively affecting the hormonal environment required for conception.
Fasting insulin is not part of a standard fertility workup but it is one of the most consistently modifiable drivers of subfertility when identified and addressed early.
Yes. A functional medicine investigation is not a replacement for reproductive medicine — it is complementary to it. Identifying and addressing the modifiable drivers of hormonal imbalance, metabolic disruption, and gut dysfunction can improve the conditions for both natural conception and assisted reproduction.
We work alongside your existing reproductive specialist and GP, not in place of them. Our role is to build the clearest possible picture of the functional drivers and address those directly as part of a broader plan.
