PCOS Risk Assessment Calculator

About the PCOS Risk Assessment

PCOS (Polycystic Ovary Syndrome) is one of the most common hormonal disorders, affecting approximately 1 in 10 women of reproductive age. This tool provides a weighted symptom-based risk assessment grounded in Rotterdam Criteria indicators — the internationally recognised diagnostic framework. It helps identify whether your symptoms warrant further clinical investigation.

How to Use

Check all symptoms that apply to you — each has a weighted score reflecting its diagnostic significance.
Select your BMI category to account for metabolic risk factors associated with PCOS.
Choose your age range (PCOS is most prevalent between ages 20–35).
Click "Assess Risk" to view your risk level, score breakdown, and personalised recommendations.

Formula / Methodology

Rotterdam Criteria (2 of 3 required):
1. Irregular / absent menstrual cycles
2. Hyperandrogenism (excess hair, acne)
3. Polycystic ovaries on ultrasound

Weighted Score:
Score ≥ 8 → High Risk
Score 4–7 → Moderate Risk
Score < 4 → Low Risk

Symptoms are assigned weights (1–3) based on their strength as PCOS indicators. Irregular periods score highest (3) as they are the most consistent hallmark. BMI and age modifiers reflect epidemiological risk data.

Understanding Your Results

Low Risk Few or low-weight symptoms present. Continue tracking your cycle and general health. Revisit if new symptoms develop or cycles become irregular.

Moderate Risk Several relevant symptoms present. A GP or gynaecologist visit is recommended. Blood tests (androgens, insulin, LH/FSH ratio) and pelvic ultrasound can confirm or rule out PCOS.

High Risk Multiple high-weight symptoms present. Prompt medical consultation is strongly advised. Early diagnosis and management reduces long-term risks including infertility, type 2 diabetes, and cardiovascular disease.

Medical Disclaimer

This tool is for informational and self-awareness purposes only and is not a diagnostic instrument. PCOS can only be formally diagnosed by a qualified healthcare professional through clinical examination, hormone blood panels, and pelvic ultrasound. A high risk score does not confirm PCOS, and a low score does not rule it out. Please consult a gynaecologist or endocrinologist for an accurate diagnosis and management plan.
