PCOS and Fertility: How to Improve Your Chances of Getting Pregnant Naturally

Polycystic ovary syndrome (PCOS) is the most common hormonal disorder affecting women of reproductive age, estimated to affect 1 in 10 women globally — and up to 1 in 7 in some populations. It is also one of the most common, yet treatable, causes of female infertility. The good news: with the right approach, the majority of women with PCOS successfully conceive, and many do so naturally.

This guide covers everything you need to know about PCOS and fertility — from understanding why PCOS affects conception to the most evidence-based strategies for improving your chances of getting pregnant with PCOS.

What Is PCOS and How Does It Affect Fertility?

PCOS is a hormonal condition characterised by a combination of:

• Ovulatory dysfunction: Irregular or absent ovulation (anovulation)
• Hyperandrogenism: Elevated male hormones (androgens) causing symptoms like excess facial hair, acne, and hair thinning
• Polycystic ovarian morphology: Multiple small follicles visible on ultrasound (not actual "cysts")

A diagnosis typically requires two out of three of these features (Rotterdam criteria). The underlying issue in most cases of PCOS is insulin resistance — the body's cells do not respond properly to insulin, causing elevated insulin levels, which in turn disrupts hormonal signalling and interferes with ovulation.

The fertility impact of PCOS is primarily through irregular or absent ovulation. If you're not ovulating regularly — or at all — conception is impossible without intervention. Women with PCOS may ovulate occasionally, rarely, or not at all, making the fertile window highly unpredictable.

Can You Get Pregnant Naturally with PCOS?

Yes — many women with PCOS conceive naturally, without medical intervention. The key factors determining whether natural conception is achievable include:

• Whether you are ovulating at all (even irregularly)
• Partner sperm health
• Whether other fertility factors (fallopian tube patency, uterine health) are normal
• Body weight relative to your personal health baseline
• Insulin resistance severity

For women who are ovulating irregularly, timing intercourse around ovulation (using OPKs and cervical mucus monitoring) can be highly effective. For those who are not ovulating, lifestyle interventions and/or medical treatment to induce ovulation are necessary — but these are well-established and highly effective.

Step 1: Get the Right Diagnosis and Baseline Tests

If you suspect PCOS, work with your GP or gynaecologist to confirm the diagnosis and assess your fertility baseline. Key investigations include:

• Hormone panel: LH, FSH, oestradiol, testosterone, DHEA-S, SHBG, prolactin, thyroid function
• Fasting insulin and glucose: To assess insulin resistance (HOMA-IR score)
• AMH (anti-Müllerian hormone): Often elevated in PCOS due to the high number of follicles; helps assess ovarian reserve
• Transvaginal ultrasound: To assess ovarian morphology and monitor follicle development
• Progesterone level at day 21: To confirm whether ovulation occurred that cycle
• Semen analysis: For your partner — essential before assuming the issue is PCOS-related

Step 2: Lifestyle — The Most Powerful PCOS Fertility Intervention

Lifestyle modification is the first-line treatment for PCOS and fertility, supported by robust clinical evidence.

Weight and PCOS

For women with PCOS who are above their healthy weight, even a modest weight loss of 5–10% of body weight has been shown to restore ovulation in up to 82% of anovulatory women (Clark et al., Fertility and Sterility). This works by reducing insulin resistance, lowering androgen levels, and restoring the hormonal environment needed for regular ovulation.

However, PCOS affects women of all body sizes, and weight loss is not the answer for everyone. Lean PCOS is equally real and requires a different approach.

Diet for PCOS Fertility

The PCOS-friendly diet focuses on:

• Low glycaemic index (GI) foods: Whole grains, legumes, non-starchy vegetables, berries — foods that don't spike blood sugar and insulin
• Anti-inflammatory foods: Oily fish (salmon, sardines), leafy greens, olive oil, nuts, seeds
• Adequate protein: Supports stable blood sugar and satiety
• Limiting processed foods, refined carbohydrates, and added sugars: These directly worsen insulin resistance
• Dairy considerations: Some women with PCOS find that reducing dairy lowers androgens; evidence is mixed — trial and observe

Exercise for PCOS Fertility

Regular physical activity improves insulin sensitivity, lowers androgens, and supports ovulation. Aim for:

• 150+ minutes per week of moderate aerobic exercise (brisk walking, cycling, swimming)
• Resistance training 2–3 times per week (shown to specifically improve insulin sensitivity)
• Avoid excessive high-intensity exercise, which can further stress the adrenal axis

Step 3: Supplements That Support PCOS Fertility

Several supplements have strong evidence for supporting ovulation and hormonal balance in women with PCOS:

Myo-Inositol (and D-Chiro-Inositol)

Inositol is one of the most well-studied supplements for PCOS. Multiple randomised controlled trials show that myo-inositol (the most effective form) improves insulin sensitivity, lowers androgen levels, and — critically — restores regular ovulation in a significant proportion of women with PCOS. A landmark meta-analysis found that myo-inositol supplementation increased clinical pregnancy rates compared to placebo.

The ideal ratio for PCOS appears to be 40:1 myo-inositol to D-chiro-inositol (e.g. 2000mg myo + 50mg D-chiro), which mirrors the natural physiological ratio in human follicular fluid.

Folate (Methylfolate)

Essential before and during early pregnancy for neural tube development. Women with PCOS may have impaired folate metabolism due to MTHFR gene variants, making methylfolate (the active form) preferable to folic acid.

Vitamin D

Vitamin D deficiency is extremely common in women with PCOS (affecting up to 85% in some studies). Vitamin D receptors are present in ovarian tissue, and supplementation has been shown to improve menstrual regularity and ovulation frequency. Aim for 25(OH)D blood levels above 75 nmol/L.

CoQ10

Coenzyme Q10 is a potent mitochondrial antioxidant important for egg quality. The energy demands of ovulation and early embryo development are substantial, and CoQ10 supports the mitochondrial function needed to meet these demands. Ubiquinol (the active form) is better absorbed than ubiquinone.

Omega-3 Fatty Acids

Anti-inflammatory omega-3s (DHA and EPA) help reduce the low-grade inflammation characteristic of PCOS and have been shown to lower testosterone levels and improve menstrual regularity.

Magnesium

Magnesium improves insulin sensitivity and is commonly depleted in PCOS. Magnesium glycinate or citrate are the most bioavailable forms.

Conceive Plus fertility supplements for women contain many of these evidence-based nutrients — including inositol, methylfolate, vitamin D, CoQ10, and key minerals — formulated specifically to support women TTC, including those with PCOS.

Step 4: Ovulation Tracking with PCOS

Tracking ovulation with PCOS requires a different approach than for women with regular cycles:

• Standard OPKs: May give false positives due to elevated LH in PCOS. Advanced digital monitors tracking the LH/oestrogen ratio are more reliable.
• Cervical mucus monitoring: Still useful and not affected by hormonal irregularities in the same way as OPKs.
• BBT tracking: Valuable for confirming ovulation retrospectively; expect irregular patterns with PCOS.
• Progesterone blood test (day 21 or 7 days post-ovulation): Confirms whether ovulation occurred that cycle.
• Ultrasound monitoring: The most accurate method for women with PCOS — your GP or specialist can monitor follicle growth and confirm ovulation.

Step 5: Medical Treatment for PCOS and Fertility

When lifestyle and supplements alone are insufficient, medical options include:

• Letrozole (Femara): Currently the first-line ovulation induction medication for PCOS. More effective than Clomid with lower risk of multiple pregnancy. Live birth rates of 27.5% per cycle in PCOS patients (NEJM, 2014).
• Clomifene (Clomid): Older but still widely used ovulation induction agent. Effective in 75–80% of PCOS patients for inducing ovulation.
• Metformin: An insulin-sensitising medication that can restore ovulation in some women with PCOS, particularly those with significant insulin resistance. Often used alongside letrozole.
• Gonadotrophins (FSH injections): Used when oral agents fail; require careful monitoring to avoid ovarian hyperstimulation.
• Laparoscopic ovarian drilling: A surgical procedure that can restore ovulation; used when medications have failed.
• IVF: For cases that don't respond to other treatments or when additional factors are present.

PCOS and IVF: What You Should Know

Women with PCOS typically respond very well to IVF stimulation — sometimes too well, with a higher risk of ovarian hyperstimulation syndrome (OHSS). Modern IVF protocols use antagonist protocols and lower stimulation doses to mitigate this risk. Elective frozen embryo transfers (rather than fresh) are also recommended to reduce OHSS risk.

Success rates in IVF for women with PCOS are generally good, since the core issue is ovulation, not egg quality — and IVF bypasses the ovulation problem. Egg quality can be supported with CoQ10 and other antioxidants in the months leading up to IVF.

FAQ: PCOS and Getting Pregnant

Q: How long does it take to get pregnant with PCOS?

A: With appropriate treatment (ovulation induction if needed), most women with PCOS conceive within 6–12 months. Natural conception timelines vary widely depending on ovulation frequency.

Q: Can I get pregnant with PCOS without medication?

A: Yes, especially if you are still ovulating — even irregularly. Lifestyle changes (diet, exercise, supplements) and precise ovulation tracking can make natural conception achievable.

Q: Does PCOS cause miscarriage?

A: Women with PCOS have a slightly elevated risk of miscarriage (20–40% vs 10–15% in the general population), likely related to elevated androgens and insulin resistance. Managing these with lifestyle measures and potentially metformin may reduce this risk. Always discuss with your doctor.

Q: Is inositol better than metformin for PCOS fertility?

A: Both improve insulin sensitivity, but inositol is a natural supplement with a very favourable safety profile and no prescription required. Studies comparing the two show similar outcomes in many measures, making inositol a reasonable first step before pharmaceutical intervention.

Q: Can I get pregnant with PCOS if my periods are very irregular?

A: Yes, but it's more challenging without medical support. Even with very irregular cycles, ovulation can occur unpredictably. OPKs (or ultrasound monitoring) help identify when ovulation does happen.

Q: Does PCOS affect IVF success rates?

A: PCOS generally does not reduce IVF success rates and may improve embryo yield due to high ovarian reserve. The main concern is OHSS risk, which modern protocols manage effectively.

Q: What is the fastest way to get pregnant with PCOS?

A: The fastest route for most women with PCOS is: confirm whether you're ovulating, optimise lifestyle and supplements, and if ovulation is irregular or absent, start ovulation induction (letrozole) with your doctor promptly rather than waiting months to see if natural conception occurs.

Q: Are Conceive Plus supplements suitable for women with PCOS?

A: Yes. Conceive Plus women's fertility supplements contain inositol, methylfolate, CoQ10, vitamin D, and other nutrients shown to support hormonal balance and reproductive function in women with PCOS.

Q: How does weight affect PCOS fertility?

A: For overweight women with PCOS, even 5–10% weight reduction can restore ovulation in many cases. For lean women with PCOS, weight management is less central; focus shifts to diet quality, insulin sensitivity, and hormonal support.

Q: When should I see a fertility specialist about PCOS?

A: If you have been TTC for 6 months without success (or 12 months if under 35), see your GP first for initial tests. If ovulation is confirmed as irregular or absent, a referral to a reproductive endocrinologist is appropriate at any point.
