PCOS Symptom
Awareness Checklist
Understand the 3 Rotterdam criteria categories used in PCOS evaluation, and see which features may be worth discussing with your doctor.
A PCOS diagnosis generally requires 2 of these 3 categories, confirmed by a doctor through examination and testing — not just symptom review. Select anything you've noticed to see which categories may be worth discussing at your next appointment.
| Category | What It Means | How It's Confirmed |
|---|---|---|
| Hyperandrogenism | Clinical signs (hirsutism, acne, hair loss) or elevated androgens on bloodwork | Exam + blood test |
| Ovulatory Dysfunction | Irregular, infrequent, or absent ovulation/periods | Menstrual history |
| Ovarian Findings | Polycystic-appearing ovaries or elevated AMH | Ultrasound or blood test |
Diagnosis requires 2 of these 3 categories, AND exclusion of other causes (thyroid disorders, elevated prolactin, etc.) by a doctor.
What Are the Rotterdam Criteria?
This checklist organizes common features by these three categories specifically to help you understand the framework doctors use, and to help you organize what's relevant to bring up at an appointment — it is deliberately not designed to tell you whether you have PCOS, since that genuinely requires bloodwork and clinical evaluation that a self-assessment simply cannot replicate.
Why Excluding Other Causes Matters So Much
A defining, easily overlooked feature of the Rotterdam criteria is that meeting 2 of the 3 categories is not enough on its own — other conditions that can cause similar features must first be ruled out. Thyroid disorders (both an underactive and overactive thyroid) can cause irregular periods; see our Thyroid TSH Reference Range Checker if this is relevant to your situation. Elevated prolactin (hyperprolactinemia) can also cause ovulatory dysfunction. This is exactly why proper PCOS evaluation always includes bloodwork beyond just androgen levels — it's ruling out these overlapping conditions, not just confirming PCOS-specific findings, that makes the diagnosis reliable.
Why Adolescent Diagnosis Is Handled Differently
👩 Adults
Any 2 of the 3 Rotterdam categories, with ultrasound/AMH testing considered a reliable diagnostic tool once other causes are excluded.
👧 Adolescents
Both hyperandrogenism AND ovulatory dysfunction are specifically required together — ultrasound and AMH are not recommended for diagnosis in this age group, since irregular cycles and polycystic-appearing ovaries are both common, often temporary, normal findings during adolescent development.
This distinction exists precisely because applying adult diagnostic thresholds to adolescents would lead to significant overdiagnosis — many teenagers experience irregular periods and multi-follicular ovaries as a normal part of reproductive maturation, not as a sign of PCOS specifically.
How UK NICE Guidance Compares
UK clinical practice, guided by NICE (National Institute for Health and Care Excellence), also endorses the Rotterdam criteria as the diagnostic standard, aligning with the international 2023 guideline rather than using a separate UK-specific framework — this is one of the relatively few areas of women's health where global consensus is genuinely strong rather than split by country. NHS guidance similarly emphasizes that diagnosis requires clinical assessment and appropriate testing rather than symptoms alone, and places similar emphasis on excluding thyroid disorders and other overlapping conditions before confirming a PCOS diagnosis. Where some practical variation exists between countries is in access and typical evaluation pathway — for example, which specialist (GP, gynecologist, or endocrinologist) typically leads initial evaluation — but the underlying diagnostic framework itself remains internationally consistent.
Beyond Diagnosis: Why PCOS Awareness Matters
PCOS is one of the most common hormonal conditions affecting women of reproductive age, and its effects extend beyond fertility and menstrual regularity — it's also associated with increased risk of insulin resistance and type 2 diabetes, which is why metabolic health assessment is typically part of a thorough PCOS evaluation. Our HOMA-IR Insulin Resistance Calculator covers this related metabolic marker, and given the hormonal overlap, some clinicians may also assess androgen levels alongside our Free Testosterone Calculator for a fuller hormonal picture, though these calculators are informational tools, not substitutes for your doctor's actual test interpretation.
What to Bring to Your Doctor's Appointment
- Menstrual cycle history — tracking cycle length and regularity over the past several months provides genuinely useful diagnostic information
- Specific symptoms and when they started — hirsutism, acne pattern, or hair thinning timeline
- Family history — PCOS and related metabolic conditions often run in families
- Any prior test results — bring copies of previous bloodwork or ultrasound reports if available
- Your checklist results from this tool — can help structure the conversation, though your doctor will still need to run their own evaluation
