Functional Fertility: Treating Your Health From Head to Toe
Every fertility story is different — but almost all share one thing in common: the feeling that something deeper is being missed.
At The Functional MDs, we specialize in helping women and couples who have tried everything and still don’t have answers. Our Functional Fertility Programs are designed for those who want a more complete, data-driven, and physician-supervised approach to conception.
We look beyond the reproductive system to uncover imbalances in gut and microbiome health, thyroid and adrenal function, chronic infections and inflammation, nutrient deficiencies and toxin exposure, and immune and hormonal regulation.
Whether you’re trying to conceive naturally, preparing for IVF, or recovering from pregnancy loss, we help you optimize your body so conception happens naturally or with support from a fertility clinic.
Who This Program Is For
No matter where you’re starting, our care is personalized, physician-led, and designed to support whole-body wellness. We guide you toward improved reproductive health and a healthier path to conception.
Preparing for Natural Conception:
Our approach focuses on strengthening overall health so conception happens more naturally and with fewer complications.
Struggling to Conceive:
Our team identifies hidden issues traditional testing often misses - from gut health and inflammation to immune or thyroid imbalances - to uncover what’s truly blocking conception.
IVF / IUI Preparation:
We optimize the body’s internal environment to increase the chances of success. This includes improving hormone balance, reducing inflammation, and supporting egg and sperm quality.
Recurrent Miscarriages:
We support individuals and couples navigating repeated loss by identifying root causes such as nutrient depletion, autoimmune activity, or environmental triggers.
Meet Your Doctor
At The Functional MDs, we specialize in holistic, functional medicine for patients across Indiana. Our mission is simple: address the root cause of your health concerns, not just the symptoms.

Dr. Sanna, MD, DABOM,
FMACP
I’m Dr. Sanna Singh, a double board-certified physician in Internal Medicine and Obesity Medicine, with advanced certification in Functional Medicine and more than 13 years of experience supporting women’s health. My work centers on hormone balance, functional fertility, and the full spectrum of women’s health from perimenopause and menopause to metabolic optimization.
I understand what it feels like when your body seems to be working against you, but it isn’t.
My goal is to uncover why that dysfunction exists and guide your body back to its optimal state of health. By combining conventional medicine with personalized functional approaches, I help women restore clarity, energy, hormone balance, and ultimately, fertility so reproduction becomes a natural reflection of renewed vitality and whole-body wellness.
“My mission is simple: to listen, to uncover the root cause of illness, and to guide each patient toward lasting health. True healing isn’t about masking symptoms, it’s about restoring balance and trust in your body.”

Questions? We've got answers
Choosing a new doctor or trying functional medicine for the first time can bring up lots of questions. We’ve made it simple, here are the answers to the things our patients ask us most often.
How is Functional Medicine Different?
Conventional medicine often focuses on diagnosing conditions and managing symptoms, usually through medication or procedures. Functional medicine takes a broader, systems-based approach. We look for the root causes of illness by considering lifestyle, environment, and underlying biological imbalances. The goal is long-term healing and prevention, not just symptom control.
For example, instead of simply prescribing medication for high blood pressure, a functional medicine physician may also evaluate genetics, metabolomics, stress response, sleep, gut health, and nutrition, recognizing how all these systems interact and contribute to your condition.
As for primary care, most patients keep their existing PCP while adding functional medicine to their care team. However, we also offer a concierge-style Direct Primary Care program, where your primary physician is also a functional medicine expert. This gives you the flexibility to choose: functional medicine only, concierge primary care only, or a combination of both.
What kind of testing do you perform?
We use advanced functional and integrative testing to uncover hidden imbalances. This may include hormone panels, thyroid and adrenal testing, gut and microbiome analysis, inflammation markers, toxin and nutrient testing, and immune system evaluation. Every plan is customized to your unique needs and biology.
Do you accept insurance?
We do not bill insurance for our services. Our membership is direct-pay, which allows us to provide longer visits, personalized care, and advanced testing without the restrictions of traditional insurance. Many patients are able to use HSA or FSA funds toward their membership, check with your plan to confirm eligibility.
For labs:
Routine labs (CBC, CMP, thyroid, cholesterol, etc.) are usually covered and billed through your insurance at national labs like LabCorp, Quest, or HealthLab.
Specialty functional medicine labs vary: some may bill insurance directly, but many are out-of-network and require patient payment.
Before ordering any test, we review coverage and pricing with you so there are no surprises. Whenever possible, we use insurance-eligible options first and clearly explain which specialty tests may involve additional out-of-pocket costs.
What is a Functional Fertility Program?
Our Functional Fertility Program takes a whole-body, root-cause approach to reproductive health. Instead of focusing only on the reproductive organs or procedures like IVF, our MD-led team investigates all the systems that impact fertility, including hormones, gut health, immune balance, toxins, stress, and nutrition. This approach helps identify and correct what’s preventing conception or contributing to pregnancy loss.
How is this different from traditional fertility treatment?
Traditional fertility clinics typically focus on assisted reproduction procedures like IUI or IVF. We focus on preparing your body to conceive naturally or improve the success of those treatments. Using advanced functional testing and personalized care, we find what’s causing the fertility challenges and restore balance so your body can function optimally.
How soon can I expect results?
Every patient is different, but many begin noticing improvements in energy, cycle regularity, and overall health within 1–3 months. For conception goals, timelines depend on individual findings, but by optimizing your health at the root level, we help you build the strongest possible foundation for fertility and long-term wellness.
