Over the years, I have had many patients come into my office with a folder full of fertility test results and the same frustrating story. Their FSH is normal, their tubes are open, their partner's semen analysis looks fine, and perhaps even their AMH is within the expected range for their age. They have been reassured that everything looks normal, yet they still aren't pregnant.

The usual fertility evaluation gives us important information. We need to know whether you are ovulating, whether your fallopian tubes are open, what your ovarian reserve looks like, whether there are fibroids or polyps, and whether sperm count, movement and morphology are within expected ranges. I wouldn't want to pursue fertility treatment without that information. But there are times when the results don't fully explain what is happening, because fertility is influenced by much more than the reproductive organs and a handful of hormone values.

The ovaries, uterus and hormones are functioning within the same body as your digestive system, metabolism, immune system and microbiome. They are affected by the nutrients available to you, your blood sugar regulation, sleep, circulation, inflammation and stress physiology. This is why I was interested in talking with Nora DeBora, a functional fertility coach, holistic nutritionist and fertility awareness practitioner, about when additional testing may be useful and, equally important, when it may not be necessary.

When Does More Testing Make Sense?

There are now tests available for almost every aspect of our physiology. We can measure hormone metabolites, cortisol patterns, nutrients, organic acids, stool bacteria and vaginal microorganisms, along with increasingly sophisticated metabolic and inflammatory markers. Having access to all of this information doesn't mean everyone needs all of it.

I prefer to begin with what we already know about the person. Menstrual cycles, ovulation patterns, digestive symptoms, recurrent infections, sleep, blood sugar, menstrual pain, pregnancy losses and previous fertility treatments can help determine whether there is an area that deserves more investigation. Someone with chronic digestive symptoms may benefit from a very different evaluation than someone with irregular cycles or recurrent bacterial vaginosis.

Nora and I discussed the DUTCH test as one example. This dried urine test measures hormone metabolites, which gives us different information from a blood test. Bloodwork measures circulating hormone levels at the time the sample is taken, while urine metabolites can provide information about how certain hormones are being processed. That may be useful when there is a reason to investigate hormone metabolism, but I wouldn't automatically recommend it to every person trying to conceive. Before ordering a test, I want to know what we hope to learn and whether the result is likely to change the plan.

The Fertility Supplement Cabinet

Most fertility patients I meet are already taking supplements, and many are taking quite a few. CoQ10, prenatal vitamins, vitamin D, omega-3s, NAC, inositol, DHEA, melatonin and various herbs frequently find their way into a daily routine. Recommendations come from practitioners, friends, fertility groups, podcasts and late-night internet searches, and it doesn't take long for the list to become extensive.

I understand the desire to cover every possible base, especially when so much about fertility feels outside of your control. I am more interested in knowing why you are taking something and whether it makes sense for you. If vitamin D is low, we can address vitamin D. If blood sugar regulation needs attention, that deserves its own plan. If there are signs of poor digestion or absorption, adding more supplements may accomplish very little until we understand what is happening in the gut.

Functional testing can sometimes help us become more specific about those decisions. Its value isn't in generating a longer supplement list. Its value is in helping us decide where attention is most likely to make a difference.

What Does Your Gut Have to Do With Fertility?

When I began working in fertility nearly 25 years ago, the microbiome was not part of the everyday fertility conversation. We now know considerably more about the communities of bacteria and other microorganisms that live in the digestive and reproductive tracts and the ways they interact with digestion, nutrient absorption, immune function and inflammation.

The gut microbiome is particularly important because of its relationship with the immune system. When the balance of organisms changes significantly, or dysbiosis develops, the effects can extend beyond digestive symptoms. This is one reason I pay attention when a fertility patient also tells me about chronic bloating, constipation, diarrhea, food sensitivities or a long history of digestive problems.

There are also women who don't have obvious digestive symptoms but have dealt with recurrent bacterial vaginosis, yeast infections or UTIs for years. They are treated, feel better for a while, and then the problem returns. After several rounds of the same cycle, it makes sense to look more closely at why the infection keeps recurring and what the microbial environment looks like between episodes.

The Reproductive Tract Has a Microbiome Too

The vaginal microbiome normally contains protective bacteria, particularly Lactobacillus species, which help maintain the environment and discourage the overgrowth of potentially harmful organisms. When that balance is disrupted, some women become more susceptible to BV, yeast infections and other recurrent symptoms.

Nora and I also discussed testing of the vaginal and uterine microbiomes. These tests are not routinely necessary for everyone trying to conceive, but they may be worth discussing in the presence of recurrent infections, suspected endometritis, repeated implantation failure or unexplained pregnancy loss. Some tests provide information about both potentially problematic organisms and the protective bacteria that are present, which can be useful when deciding how to restore the microbial environment after treatment.

Biofilms add another layer to this discussion. Some microorganisms can form a protective matrix that makes them more difficult to treat, which may contribute to an infection improving temporarily and then returning. In certain cases, the partner may also need to be considered, particularly when there is concern that an organism is being passed back and forth. Treating the same person repeatedly without considering these other factors can keep the cycle going.

Your Eggs Are Developing Within Your Health

One of the concepts I have taught fertility patients throughout my career is that the egg you hope will become your future baby has been developing for months before ovulation. During that time, the follicle and egg are dependent upon nutrients, circulation, cellular energy production and the metabolic environment of the body in which they are growing. Sperm also require months to develop, which is why preconception health belongs to both partners.

This is the reason I encourage people to think about pregnancy preparation well before the cycle in which they hope to conceive. Nutrition, blood sugar regulation, sleep, movement, circulation, stress resilience and reducing unnecessary inflammatory burden are areas where we may have some ability to influence the environment in which eggs and sperm are developing.

Of course, improving health cannot guarantee a pregnancy or a healthy embryo. Age, genetics, reproductive anatomy and many other factors remain important. Preconception care gives us an opportunity to work with the areas that can reasonably be influenced while appropriate fertility evaluation and treatment continue.

Putting AMH in Perspective

AMH is one of the fertility numbers that creates the most anxiety, and I regularly meet women who have interpreted a low result as a statement about their ability to become pregnant. AMH is useful because it provides information about ovarian reserve and helps reproductive endocrinologists estimate how someone may respond to ovarian stimulation. It does not directly measure egg quality.

A low AMH deserves attention, particularly when age and reproductive timing are concerns, but it should be interpreted alongside antral follicle count, menstrual history, age, previous response to fertility treatment and the rest of the clinical picture. I also want to pay attention to the health of the person whose remaining follicles are developing.

For women in their late 30s and early 40s, this sometimes means working on preconception health while moving forward with fertility treatment. Egg retrieval or embryo banking and improvements in nutrition, sleep, metabolic health, digestion and circulation do not always have to happen sequentially. Depending on the individual situation, they can happen alongside one another, with the fertility team helping to determine the appropriate timing.

Testing Should Help You Make Decisions

The number of tests available in fertility and functional medicine can quickly become overwhelming. Bloodwork, DUTCH testing, stool analysis, vaginal microbiome testing, endometrial testing, metabolic markers and nutrient testing may all have a place, but their usefulness depends upon the person sitting in front of us.

I would rather begin with a thorough history and identify the areas that stand out. Recurrent BV may lead us in one direction, while long irregular cycles and signs of insulin resistance lead us in another. Chronic digestive problems suggest another place to investigate, and recurrent pregnancy loss or failed embryo transfers may require an entirely different evaluation.

This is also why I don't see conventional and functional medicine as competing approaches to fertility. Conventional reproductive medicine gives us information and treatments we cannot replace. Functional testing can sometimes add another layer when there is a specific reason to look further. Acupuncture and Traditional Chinese Medicine bring another perspective, particularly around patterns of function, circulation and the changes that occur throughout the menstrual cycle. Nutrition and lifestyle are part of the same conversation.

After nearly 25 years of working with fertility patients, I don't believe one practitioner, one laboratory test or one model of medicine has all of the answers. I want the information that helps us understand the individual person and make better decisions about what comes next.

Preparing for the Pregnancy You Want

When someone comes to me for fertility care, getting pregnant is obviously the immediate goal. But my concern extends beyond the positive pregnancy test. We are preparing for a pregnancy, a placenta, a developing baby and the enormous physiological work the body will be asked to do over the months that follow.

That is why preconception health matters so much to me. If there is time to improve nutritional status, stabilize blood sugar, address digestive or microbiome problems, improve sleep, support circulation and investigate symptoms that have been ignored, I want to use that time well.

If your fertility evaluation has come back normal and you are still having difficulty conceiving, you may not need a long list of functional tests. Your history may point toward one or two areas that are worth investigating further. The useful question is what information is missing from your particular fertility picture and whether finding it could change what you do next.

Fertility care is personal. The testing and treatment should be personal too.
