PCOS and Insulin Resistance: How They Affect Your Fertility

Expert insights from Dr. Nadine Al Kaisi – Fertility Doctor & Fertility Coach serving Palo Alto, Los Gatos, and the wider Silicon Valley/Bay Area

Polycystic Ovary Syndrome (PCOS) is the most common hormonal condition I see in my practice at Eggcellent Fertility here in Palo Alto. Yet many high‑achieving women are surprised to learn that PCOS is often driven by insulin resistance—a metabolic imbalance that silently undermines ovulation, egg quality, and long‑term health. In this article, I’ll explain the PCOS–insulin connection, show you how to spot the signs, and share science‑backed strategies you can start today to improve fertility outcomes.

Quick takeaway: Addressing insulin resistance is one of the fastest ways my Silicon Valley clients turn irregular cycles into predictable ovulation and successful pregnancies.

What Exactly Is PCOS?

PCOS is a complex endocrine disorder characterized by at least two of the following (Rotterdam criteria):

1. Irregular or absent ovulation

2. Clinical or laboratory signs of androgen excess (e.g., acne, hirsutism, elevated testosterone)

3. Polycystic‑appearing ovaries on ultrasound ("string‑of‑pearls" follicles)

Worldwide, PCOS affects up to 1 in 10 women of reproductive age, but in tech‑heavy regions like the Bay Area—where sedentary work, high stress, and on‑the‑go eating are common—the incidence may be even higher.

Understanding Insulin Resistance

Insulin is the hormone that shuttles glucose from your bloodstream into cells for energy. Insulin resistance (IR) occurs when those cells stop responding efficiently, forcing the pancreas to pump out more insulin. Chronically high insulin levels can:

• Stimulate ovarian theca cells to produce excess androgens

• Disrupt normal follicle maturation and ovulation

• Increase fat storage and inflammation, further worsening hormonal balance

Key point: Up to 70–80 % of women with PCOS have some degree of insulin resistance—even if they are lean and athletic.

How Insulin Resistance Fuels PCOS Symptoms & Infertility

When ovulation is sporadic, timing intercourse or intrauterine insemination (IUI) becomes a guessing game—and IVF cycles may yield fewer mature eggs.

Signs You May Have Insulin Resistance

• Midsection weight gain despite healthy habits

• Sugar or carb cravings after meals

• Fatigue or “brain fog” in the afternoon

• Dark, velvety skin patches (acanthosis nigricans) on neck or underarms

• Lab clues: elevated fasting insulin (> 10 µIU/mL), HOMA‑IR > 2, or HbA1c creeping above 5.6 %

If these sound familiar, book a PCOS & Metabolic Assessment at my Palo Alto or Los Gatos office (virtual coaching available across California).

Testing & Diagnosis: A Fertility Doctor’s Checklist

1. Comprehensive metabolic panel & fasting insulin

2. Oral Glucose Tolerance Test (OGTT) with insulin curves—not just glucose

3. Hormone panel: LH, FSH, estradiol, total & free testosterone, DHEA‑S, SHBG

4. Transvaginal ultrasound to evaluate follicle count and ovarian volume

5. Thyroid & adrenal screening – because PCOS rarely travels alone!

Pro tip: Bring previous labs to your first Eggcellent Fertility coaching session so we can track trends—not just single snapshots.

Evidence‑Based Ways to Improve Insulin Sensitivity & Boost Fertility

1. Nutrition that Balances Blood Sugar

• Focus on fiber‑rich, low‑GI carbs (quinoa, legumes, berries) plus protein and healthy fats at every meal.

• Aim for 25–30 g fiber/day—studies show it lowers insulin and androgen levels.

• Consider a 12‑ to 14‑hour overnight fast (a gentle form of time‑restricted eating) proven safe in women trying to conceive.

2. Strength & Movement Breaks for Tech Lifestyles

A Stanford study found that 60 minutes of moderate exercise weekly (think brisk walks between Zoom calls) increased ovulation by 30 % in insulin‑resistant PCOS patients. Add two 20‑minute strength sessions to build muscle—the biggest insulin sponge we have.

3. Targeted Supplements

(Always discuss with your healthcare provider before starting new supplements.)

4. Medications & Advanced Therapies

• Metformin remains the first‑line insulin‑sensitizer. In my clinic we often combine it with lifestyle coaching for synergistic results.

• Glucagon‑like peptide‑1 (GLP‑1) receptor agonists (e.g., semaglutide) show promise in weight‑neutral PCOS—clinical trials are under way at UCSF and across the Bay Area.

• Ovulation induction with letrozole or low‑dose gonadotropins once insulin is controlled improves live‑birth outcomes by up to 40 %.

When to Seek Fertility Coaching & Medical Support

If you’re under 35 and have gone > 6 months without a positive pregnancy test—or if your cycles are longer than 35 days—schedule a strategy session with a Fertility Doctor or Coach in Silicon Valley. Early intervention prevents years of emotional stress and costly failed cycles.

What a Personalized Eggcellent Fertility Plan Looks Like

1. Advanced Reviewing all your labs reviewed 

2. Custom nutrition roadmap designed for Bay Area produce and restaurant culture

3. Lifestyle Optimization  (essential for ambitious tech professionals)

4. Medication and supplement tuning for optimal ovulation

5. Ongoing coaching & accountability via video calls—perfect for busy Palo Alto and Los Gatos residents

Clients typically see cycle‑length normalization within 3 months and a significant rise in natural conception rates or IVF success.
