PCOS Symptom Checker

Screen for polycystic ovary syndrome symptoms based on the Rotterdam criteria. Answer questions about your menstrual cycle, skin, and hair patterns to assess your PCOS risk level. This is not a diagnosis — always consult a healthcare provider.

Medical Disclaimer: This tool is a screening questionnaire only and does not provide a medical diagnosis. PCOS can only be diagnosed by a qualified healthcare professional through clinical examination, blood tests, and ultrasound imaging. If you suspect you have PCOS, please consult your doctor.

What Is PCOS?

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders affecting women of reproductive age, estimated to affect 6 to 12 percent of women worldwide according to the CDC. It is a hormonal condition characterized by elevated androgen levels, irregular ovulation, and in many cases, multiple small cysts on the ovaries visible on ultrasound. PCOS is a leading cause of infertility and is associated with metabolic complications including insulin resistance, type 2 diabetes, and cardiovascular risk factors. Early screening and lifestyle modifications can significantly improve outcomes. Last updated: April 2026.

How the PCOS Symptom Checker Works

This screening tool evaluates your symptoms against the Rotterdam criteria, the internationally recognized diagnostic framework established by the European Society of Human Reproduction and Embryology (ESHRE) and the American Society for Reproductive Medicine (ASRM) in 2003. A PCOS diagnosis requires meeting at least 2 of 3 criteria: oligo-anovulation (irregular or absent periods), clinical or biochemical hyperandrogenism (excess hair growth, acne, or hair thinning), and polycystic ovaries on ultrasound. Your answers are scored to estimate which criteria may apply, and you receive a risk level with recommended next steps.

PCOS Symptoms to Watch For

Common signs of PCOS include irregular menstrual cycles (fewer than 8 periods per year), excess facial or body hair growth called hirsutism (affecting up to 70 percent of women with PCOS per the Androgen Excess Society), persistent acne particularly along the jawline and chin, thinning hair on the scalp (androgenic alopecia), unexplained weight gain especially around the abdomen, and patches of darkened skin called acanthosis nigricans. Fertility difficulties are also frequently reported. Symptoms can vary widely between individuals, which is why a comprehensive screening approach is important.

When to See a Doctor About PCOS

You should consult a healthcare provider if you experience two or more of the symptoms described above, especially if your periods are consistently irregular or absent. A doctor can order blood tests to check androgen levels, insulin, and other hormones, and may recommend a pelvic ultrasound. Early diagnosis allows for management strategies including lifestyle changes, medication for insulin resistance such as metformin, and hormonal treatments that can regulate cycles and reduce androgen-related symptoms. If you are trying to conceive and suspect PCOS, seek a referral to a reproductive endocrinologist.
