PCOS and Fertility: How It Affects Conception and What Helps

Polycystic ovary syndrome (PCOS) is one of the most common causes of irregular ovulation. It doesn't mean you can't have a baby — many women with PCOS conceive with lifestyle changes, medication, or fertility treatment.

How PCOS affects fertility

PCOS can cause irregular or absent periods, meaning ovulation doesn't happen predictably. Higher AMH and multiple small follicles on ultrasound are common. Weight, insulin resistance, and hormones all play a role.

What can help

• Weight loss if overweight — even modest loss can restore ovulation
• Regular exercise and balanced nutrition
• Ovulation-inducing medication prescribed by a doctor
• Metformin in some cases — discuss with your clinician
• Fertility treatment (IUI or IVF) if simpler steps don't work

Paths to pregnancy with PCOS

Most women with PCOS do go on to conceive. The usual first step is helping ovulation happen more regularly — through weight and lifestyle changes where relevant, and ovulation-inducing medication prescribed by a doctor. If those don't work after a fair trial, treatments such as IUI or IVF are options. Because ovulation can be unpredictable, tracking with an ovulation predictor kit can be less reliable in PCOS, so your doctor may monitor cycles with scans or blood tests instead.

When to speak to a doctor

See a doctor early if your periods are irregular or absent and you're trying to conceive — don't wait the usual 12 months, because irregular ovulation is itself a reason to get help sooner. Also seek advice if you have symptoms like excess hair growth, acne or unexplained weight changes, or if you've been diagnosed with PCOS and want to plan ahead. Managing insulin resistance, thyroid and weight before trying can make treatment more effective.

Common misunderstandings

• PCOS does not mean you're infertile — many women conceive with the right support
• You can have PCOS without visible 'cysts' — the name is misleading
• A high AMH in PCOS reflects egg quantity, not better egg quality
• Ovulation kits can mislead in PCOS, so don't rely on them alone
