PCOS AND FERTILITY
What the Latest Research Actually Says About Getting Pregnant With PCOS
By Katie Rice | Accredited Naturopath & Nutritionist | Her Herbs Founder
If you have PCOS and you want to have children, you've probably already fallen down a Google rabbit hole that left you more anxious than informed. So let's cut through it.
PCOS is one of the most common causes of female subfertility. That's the honest answer. But subfertility is not infertility, and for most women with PCOS, pregnancy is achievable. What it often requires is the right support, the right timing, and a clear understanding of what's actually going on in your body.
Why PCOS Affects Fertility
The core issue is ovulation. PCOS disrupts the hormonal signals that trigger the ovaries to release an egg, so cycles are often irregular, unpredictable, or absent altogether. If you're not ovulating consistently, the window for conception is either narrow or very hard to find.
This is why women with PCOS can spend months trying to conceive without success, not because conception is impossible, but because the timing piece is genuinely harder to pin down.
What the Evidence Says About Ovulation Induction
The good news is that ovulation induction is well-studied in PCOS and it works.
Letrozole is currently the preferred first-line treatment in clinical guidelines, and the evidence continues to support it as the most effective option for improving pregnancy rates. It works by temporarily lowering oestrogen, which prompts the body to produce more FSH and stimulate ovulation.
Metformin is often discussed in the same breath, particularly for women with insulin resistance. The evidence here is more mixed. Metformin can support ovulation and metabolic function, but it doesn't consistently improve live birth rates on its own. It tends to work best as part of a broader approach rather than a standalone treatment.
For women who proceed to assisted reproduction, the data is actually encouraging. A 2025 meta-analysis found that women with PCOS undergoing ART had higher clinical pregnancy and live birth rates than women without PCOS. That's worth knowing.
Pregnancy With PCOS: A Higher-Risk Profile
This is the part that doesn't always get communicated clearly, and it should.
A 2024 systematic review found that women with PCOS have higher rates of miscarriage, gestational diabetes, hypertensive disorders of pregnancy, preterm birth, and caesarean delivery. Importantly, these risks held up even after accounting for age and BMI. This isn't just a weight story. The metabolic features of PCOS, particularly insulin resistance and elevated androgens, appear to play a direct role.
What this means practically is that pregnancy with PCOS warrants closer monitoring. Earlier screening for gestational diabetes. More frequent blood pressure checks. A care team that understands your history.
There is also emerging evidence that continuing metformin into the first trimester may reduce miscarriage risk in some women with PCOS, though this isn't yet consistent across all guidelines. It's worth raising with your GP or specialist if miscarriage has been part of your experience.
What You Can Do Now
Whether you're actively trying to conceive or just starting to think about it, there are things you can do before you even walk into a fertility clinic.
Track your cycle. Consistently. Knowing your actual cycle length, whether you're ovulating at all, and where your symptoms are concentrated across your cycle gives a practitioner a huge amount of useful information. It also helps you understand what irregular really means for you, not just in theory, but in your own data.
Address insulin resistance early. This is one of the most important levers for both fertility and pregnancy outcomes in PCOS. Insulin resistance disrupts ovulation, elevates androgens, and appears to contribute to miscarriage risk. Dietary changes, movement, sleep, and in some cases targeted supplementation can all support insulin sensitivity meaningfully. This is an area where naturopathic intervention has a real role to play.
Have an honest conversation with your GP. Ask specifically about your ovulatory function, whether blood sugar regulation has been assessed, and what the pathway looks like if natural conception is taking longer than expected. You don't need to wait until you've been trying for a year to start that conversation.
Tracking Your Symptoms
If fertility is on your radar, your symptom data matters more than you might think. Tracking cycle length, ovulation signs, energy, and any metabolic symptoms over time gives you and your practitioners a clearer picture of where you're starting from. That information shapes everything that comes next.
A Note From Katie
"Fertility conversations with PCOS patients were some of the most emotionally loaded appointments I had in clinic. Women who'd been trying for months, who felt like their body was working against them, often hadn't been told the full picture. Yes, PCOS affects ovulation. Yes, it changes the pregnancy risk profile. But it is also one of the most treatable causes of subfertility, and the metabolic piece, the insulin resistance, the inflammation, the androgen excess, is somewhere that naturopathic support can genuinely move the needle. You deserve the complete picture, not just the scary parts."
