Your blood sugar could be affecting your fertility more than you realize.

Insulin resistance and blood sugar dysregulation are one of the most overlooked root causes affecting ovulation, egg quality, hormone balance, and overall fertility.

One of the easiest ways to check? Your HOMA-IR score🧪

Here’s how to calculate it:

HOMA-IR estimates how well your body responds to insulin using two simple fasting labs:

Fasting glucose (mg/dL) × fasting insulin (μU/mL) ÷ 405

(If your glucose is reported in mmol/L, divide by 22.5 instead)

General reference ranges:

Under 2.0 = likely normal insulin sensitivity

2.0 to 2.5 = borderline — may warrant further evaluation

Above 2.5 = insulin resistance more likely

Important: there is no single universal cutoff. Your result should be interpreted alongside your full clinical picture — not in isolation which is why we talk about this with all of our patients.

Why does this matter for fertility?

In women with PCOS, insulin resistance is common and can contribute to irregular ovulation, higher androgen levels, and difficulty conceiving. Improving insulin sensitivity through nutrition, movement, and sometimes medication (like metformin or inositol) may help restore ovulatory cycles.

Even if your labs are technically “normal,” elevated insulin can disrupt ovulation, increase inflammation, worsen PCOS symptoms, and make it harder to conceive naturally.

Blood sugar balance matters for fertility more than most women realize.

If you’ve ever sat in a doctor’s office and left feeling more confused than when you walked in — this is for you.

If you’ve cried on the drive home because you felt like your concerns were minimized, your labs were “”normal”” but you still don’t feel right, or you were handed a pamphlet instead of an actual plan — this is for you.
If a pregnancy announcement from someone you haven’t spoken to since high school hit you in a way you weren’t expecting — and then you felt guilty for feeling that way — this is for you.
If you’ve been trying, and waiting, and hoping, and quietly carrying the weight of all of it while still showing up to your life every single day — this is for you.

Infertility and hormone struggles are isolating in a way that is really hard to put into words. And one of the most painful parts isn’t just the physical — it’s feeling invisible in a system that was supposed to help you, and feeling like you can’t always be honest about how hard this actually is.
You are not too sensitive. You are not overreacting. Your grief is valid, your frustration is valid, and you deserve a provider who actually listens, looks at your full picture, and walks alongside you instead of just managing your symptoms.
For those of you who are new here — I’m Dr. Zen, a Naturopathic Doctor and board-certified naturopathic endocrinologist (FABNE) specializing in hormone health, fertility, and root-cause care for women. I work with patients who are tired of being told everything looks fine when they know something isn’t. My approach is personalized, evidence-based, and built around you — not just your labs.

The right care can genuinely change everything. Not because it’s magic, but because when someone finally takes the time to understand what’s actually going on in your body, real progress becomes possible.

If you’ve been doing “everything right” and still not getting answers, this is for you. 🤍

Fertility is never just about one lab, one symptom, or one quick fix. Your hormones, ovulation, stress response, thyroid, metabolism, gut health, egg quality, and cycle patterns are all connected and deserve to be looked at together.

Inside my newest Fertility Masterclass, I’m breaking down the foundations of fertility in a way that actually makes sense, so you can better understand what your body may be trying to tell you and what steps can support your journey moving forward.

Whether you’re trying to conceive naturally, navigating PCOS or irregular cycles, preparing for IVF, or simply wanting to optimize your fertility proactively, this masterclass was created to give you clarity, education, and direction. ✨

GLP-1s and fertility? The conversation is WAY more nuanced than the internet makes it seem. 👀
For some women — especially those with PCOS/PMOS — GLP-1s can actually help restore ovulation and improve fertility outcomes by addressing the underlying insulin resistance and metabolic dysfunction driving the condition. But that same mechanism also means they can increase your chances of conceiving when you weren’t expecting it.
So what happens if you had accidental exposure before you knew you were pregnant? First — don’t panic.

Hakim et al. just published the largest meta-analysis to date on this topic in the American Journal of Obstetrics and Gynecology (April 2026), analyzing 22 studies and nearly 50,000 pregnancies with periconceptional GLP-1 exposure. They found no statistically significant association between GLP-1 use and major congenital malformations, cardiac malformations, preterm delivery, pregnancy loss, hypertensive disorders, or cesarean delivery.

There was one finding worth noting — a small but statistically significant association with renal malformations. However, the authors themselves acknowledge this was largely driven by a single large cohort with significant baseline differences between groups, and likely reflects the underlying severity of maternal disease rather than a true effect of the medication.
Their conclusion? These findings offer cautious reassurance following inadvertent exposure — but do not support routine use during pregnancy.
And that is exactly the nuance that gets lost on the internet.

This is still one study. It is not enough for us to stop counseling patients about the recommended two-month washout period before actively trying to conceive. The guidance hasn’t changed — what has changed is that if accidental exposure happened, you now have more data to have an informed conversation with your doctor instead of spiraling.
This is the kind of conversation I have with my patients regularly — because the answer is almost never as black and white as a trending post makes it seem.

Do you have PCOS/PMOS?

If you’ve spent years being told your cycles were “just irregular” or were prescribed birth control as a teenager without anyone really explaining why, this is for you.

So many women carry guilt around their diagnosis, feeling like they should have pushed harder for answers sooner. But you trusted the guidance you were given, and that’s not something to blame yourself for.

PCOS, now being renamed PMOS (Polyendocrine Metabolic Ovarian Syndrome), remains one of the most underdiagnosed and misunderstood hormonal conditions in women.

Diagnosis is based on the Rotterdam Criteria, which requires just 2 of these 3 findings:

• Irregular or absent ovulation/cycles
• Signs of elevated androgens (acne, excess hair growth, hair loss, or abnormal labs)
• Polycystic ovaries seen on ultrasound

That means you can have PCOS/PMOS without ovarian cysts. You can have it without severe acne. And you can spend years knowing something feels off without getting clear answers.

In this video, I break down what the criteria actually mean, where the confusion comes from, and why looking at the full picture matters.

If you’ve been dismissed, brushed off, or feel like something is being missed, click the link in my bio to schedule a free discovery call. We’ll talk through your concerns and see if we’re the right fit. Currently offering care in Arizona and California. 🤍

Sometimes the answers have been there all along. 🤍

After years of IVF, a difficult first pregnancy, and feeling completely unseen postpartum, this mama came to us while preparing for baby number 2 searching for clarity, support, and a different experience this time around.

By taking a deeper look into her health history and labs, we uncovered something that had been overlooked for years… iron deficiency.

From there, we created a personalized plan to truly support her body, nourish her health, and optimize her fertility naturally.

And now? She’s expecting baby number 2. Naturally. ✨

Stories like this are why individualized care matters so much. You deserve to feel heard, supported, and fully seen through every season of your fertility and motherhood journey.

If you’ve been told “everything looks normal” but still feel like something is off, there may be more to the story. Comment “SUPPORT” below and we’ll DM you the link to book a discovery call. 🤍

If I was trying to get pregnant in the next 6–12 months, these are the FIRST 3 things I’d start doing now ✨

1. Start taking folic acid now, not when you get a positive test.

Most people wait until they see those two lines to start a prenatal, but neural tube development begins within the first 28 days of pregnancy, often before you even know you’re pregnant. While you may hear a lot online about methylfolate being superior, the research that has actually demonstrated a reduction in neural tube defects is behind folic acid.

2. Swap plastic for glass or stainless steel.

Plastics can release endocrine-disrupting chemicals like BPA and phthalates, especially when heated or worn down. These compounds may interfere with estrogen and progesterone signaling, which can impact ovulation and egg quality.

3. Ditch synthetic fragrance.

“Fragrance” is a catchall term that can legally hide hundreds of chemicals, many of which have been linked to hormone disruption. Candles, laundry detergent, perfume, and lotions are common sources of daily exposure that often go overlooked.

I walk through all of this with my patients using a Room-to-Room Swap Guide that helps identify the highest-priority changes in your home, without requiring a complete lifestyle overhaul.

Which of these swaps are you already making? Comment “FERTILITY” below and I’ll DM you the link to book a discovery call and learn how we can support your journey naturally. ✨
