Root Causes of Infertility: Silent Infections, Hidden Toxins & Advanced Testing for Fertility Breakthroughs with Dr Natalie Underberg

Infertility isn’t always about age or hormones—sometimes the real culprits are hidden, silent root causes that standard medicine rarely investigates. In this powerful conversation, we explore the cutting-edge research and clinical insights that are changing the way we understand fertility struggles and recurrent pregnancy loss.

Joining me on this episode is Dr. Natalie Underberg, a leading voice in functional medicine, women’s health, and fertility. She runs her own private practice, and she is also the founder of FIG Wellness, a faith-based supplement company known for its science-backed formulations and their leading HIS&HERS prenatal vitamins — world-class products that feature industry-leading doses of crucial nutrients like 900 mg of choline, setting a new standard in perinatal nutrition and were formulated specifically by Dr. Natalie and her husban,d Dr. Jake.

Dr. Natalie has helped hundreds of couples achieve natural pregnancies by uncovering and addressing the root causes of hormonal imbalances, PCOS, gut dysfunction, and recurrent pregnancy loss. She is also the creator of The PCOS Collective and The Pregnancy Prep Academy — educational programs designed to empower women to take control of their health and fertility with personalized, root-cause care.

Her work blends clinical expertise, real-life experience, and faith-centered guidance to support couples in stewarding their health and fertility naturally, without unnecessary medications or fertility procedures.

👩‍⚕️ Dr Underberg dives deep into the underlying drivers of infertility, such as:

• Stealth infections (urea plasma, mycoplasma, H. Pylori, chronic UTIs)
• Environmental toxins like glyphosate, BPA, and microplastics that damage sperm and egg quality
• Mold exposure & hidden pathogens that trigger systemic inflammation
• Gut dysbiosis and malabsorption are linked to poor reproductive outcomes
• Chronic stress and nervous system dysregulation as overlooked fertility blockers

🧪 We also uncover game-changing testing breakthroughs you won’t hear about in most OB/GYN offices, including:

• Uterine microbiome testing via menstrual blood (new non-invasive technology!)
• Male fertility testing that goes beyond sperm count to assess DNA fragmentation & toxins
• Comprehensive stool & toxin burden testing for uncovering hidden inflammatory drivers

💡 Key takeaways:

• Early miscarriages (4–8 weeks) are often tied to uterine infections—not just “low progesterone”
• Treating both partners is essential for clearing infections & preventing reinfection
• Fertility can dramatically improve with probiotics, biofilm disruptors, and holistic protocols
• Low pregnenolone levels may be the missing hormonal link keeping couples from conceiving

If you’ve been told “everything looks fine” but are still struggling to get pregnant, this episode will open the door to new answers, advanced solutions, and hope.
