Functional Testing vs. Conventional Clinics

What functional lab tests are usually missing from standard IVF workups?

Standard IVF workups are thorough for their specific purpose, assessing ovarian reserve, tubal and uterine structure, and basic hormone levels needed to plan a treatment protocol. What they don't typically include are markers like full thyroid antibody panels, comprehensive vitamin D, iron and B12 status, fasting insulin, or broader inflammatory and gut health markers.

These aren't oversights. They're simply outside the scope of what's needed to plan and run an IVF cycle safely and effectively. A functional workup is complementary to this, filling in the wider physiological picture that can influence how well the body responds to and supports treatment, rather than replacing anything the clinic does.

Why are my fertility lab results coming back "normal" when I still can't get pregnant?

This is one of the most common and understandably frustrating experiences in fertility investigations. Standard reference ranges for "normal" are generally built from a broad population and reflect the absence of overt disease, not necessarily what's needed for reproductive function specifically. It's entirely possible to fall within a normal range and still have suboptimal function for the purposes of conception.

This is part of why functional approaches often look at where a value sits within the range, not just whether it's in range, alongside markers that aren't part of standard testing at all. "Normal" and "working well for fertility" aren't always the same thing, and that gap is often where answers are found.

What is DUTCH hormone testing, and how is full-cycle tracking different from day-3 bloodwork?a

DUTCH (Dried Urine Test for Comprehensive Hormones) is a home urine testing method that measures hormone metabolites, including oestrogen, progesterone, androgens and a full daily cortisol curve, giving a picture of how hormones are being produced and broken down over time, rather than a single moment.

Standard day-3 bloodwork captures hormone levels at one specific point in the cycle, which is useful for assessing baseline ovarian reserve markers like FSH, but it can't show how hormones change across the full cycle, including the luteal phase pattern that matters so much for implantation. Full-cycle tracking, whether through DUTCH testing or repeated blood or saliva testing across the month, gives a more complete picture of the pattern rather than a single snapshot.

How does functional preconception care differ from seeing a standard fertility nutritionist?

There's overlap between the two, and a good standard fertility nutritionist will cover diet, key nutrients and general lifestyle factors well. Functional preconception care goes a layer deeper, typically involving more comprehensive lab testing to identify specific, individual drivers, such as gut dysfunction, subclinical thyroid issues or insulin resistance, rather than working from general fertility nutrition guidelines alone.

The approach is built around testing to identify what's actually happening physiologically for that specific person, then building a plan around those findings, rather than applying the same general nutrition advice to everyone regardless of their individual results.

What is the benefit of a comprehensive functional medicine workup before starting ART?

Starting assisted reproductive technology (ART) with a fuller picture of your metabolic, thyroid, nutrient and inflammatory status means any modifiable factors affecting egg quality, sperm quality, or implantation potential can be addressed within that 90-day preparation window before treatment begins, rather than only being discovered after a cycle doesn't go as hoped.

It's not a guarantee of a different outcome, and it doesn't replace anything your clinic does. But addressing things like nutrient deficiencies, thyroid antibodies or insulin resistance beforehand means you're entering treatment with as much of the picture accounted for as possible, which many people find valuable both practically and for their own peace of mind going into treatment.
