Getting pregnant with PCOS: what works first
PCOS (now officially PMOS) is one of the most common causes of ovulation-related infertility. But most women with PCOS can get pregnant with the right help. That is the part to hold onto.
Evidence-based · Sources cited · Updated July 2026
Most women with PCOS conceive. The first-line medicine to trigger ovulation is letrozole, which the 2023 guideline recommends over the older drug clomiphene.[1] Alongside it, losing a little weight where relevant and improving insulin sensitivity can bring cycles back. See a doctor to build the plan.
The first-line medicine: letrozole
When PCOS stops you ovulating, a doctor can start a medicine to trigger it. Letrozole is the strongest drug recommendation in the 2023 guideline. It beats the older drug clomiphene on live-birth rate, roughly 27.5 percent versus 19.1 percent in the trial data the guideline cites.[1] Metformin may be added on top, especially with a raised BMI. This is prescription territory, so do not self-prescribe.
What lifestyle does
Where weight is relevant, losing 5 to 10 percent of body weight can be enough to restore ovulation on its own.[1] Improving insulin sensitivity through diet, and possibly inositol, can help cycles return too.[2] These steps are not a replacement for medical treatment. They make it work better.
Track your fertile window
If your cycles are irregular, knowing when you ovulate matters. Track your cycle so you can time the fertile window, and bring that data to your appointment. It helps a doctor see what is actually happening month to month.
Get the right help
See a doctor, or ask for a reproductive endocrinologist, to build a plan around your case. The order usually runs lifestyle first where it applies, then letrozole, then further options. It takes time, but the odds are on your side.
