The Evidence on Polycystic Ovary Syndrome, Without the Hype

Key takeaways

• Diagnosis: two of three: irregular ovulation, raised androgens, polycystic ovaries on scan
• Associated with: insulin resistance and raised type 2 diabetes risk
• Most useful single change: Ask for metabolic screening as well as hormonal assessment.
• Commonest mistake: Treating it as only a fertility issue.
• See a doctor if any of the signs under "When to speak to a doctor" below apply to you.

What it is

A common hormonal condition involving irregular ovulation, raised androgens and metabolic features. It sits within Thyroid And Hormones. The table below gives the figures guidance actually works from.

The numbers, in one place

What helps

These are worth doing. None of them needs to happen all at once.

• Ask for metabolic screening as well as hormonal assessment
• Address weight and activity, which improve both cycles and metabolic risk
• Ask about endometrial protection if you have very infrequent periods
• Discuss fertility plans early rather than after difficulty arises

What to avoid

These come up often, and several of them sound like good ideas.

• Treating it as only a fertility issue
• Assuming a scan alone makes or excludes the diagnosis
• Ignoring very infrequent periods

When to speak to a doctor

See a GP if you have fewer than four periods a year, which can allow the womb lining to thicken and needs managing. Report any bleeding between periods, after sex, or unusually heavy bleeding. Seek assessment for rapid onset of male-pattern hair growth, voice deepening or clitoral enlargement, which suggests another cause.

How this page was put together

Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
