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.
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.
Frequently Asked Questions
What is PCOS?
Polycystic ovary syndrome (PCOS) is a hormonal disorder affecting 6 to 12 percent of women of reproductive age. It involves elevated androgen levels, irregular ovulation, and often small cysts on the ovaries. PCOS can cause irregular periods, excess hair growth, acne, weight gain, and fertility difficulties.
What are the Rotterdam criteria for PCOS?
The Rotterdam criteria are the internationally accepted standard for diagnosing PCOS, established in 2003. A diagnosis requires meeting at least 2 of 3 criteria: oligo-anovulation (irregular or absent periods), clinical or biochemical hyperandrogenism (excess hair, acne, hair loss), and polycystic ovaries visible on ultrasound.
Can this tool diagnose PCOS?
No. This is a screening questionnaire only. It evaluates your symptoms against known PCOS indicators but cannot replace clinical examination, blood tests for hormone levels, or pelvic ultrasound imaging. Only a qualified healthcare professional can diagnose PCOS.
Is my data private?
Yes. All your answers are processed entirely in your browser. Nothing is sent to any server. We do not collect, store, or transmit your responses. When you close or refresh the page, your data is gone.
What should I do if my risk level is high?
A high risk result means your symptoms align with multiple Rotterdam criteria. You should schedule an appointment with a gynecologist or endocrinologist. They can order blood tests for testosterone, DHEA-S, insulin, and other hormones, and may recommend a pelvic ultrasound to check for ovarian cysts.
Can PCOS be treated?
Yes. While there is no cure for PCOS, symptoms can be effectively managed. Treatment options include lifestyle modifications such as diet and exercise, hormonal birth control to regulate periods, metformin for insulin resistance, anti-androgen medications for excess hair and acne, and fertility treatments if conception is a goal.
Does PCOS affect fertility?
PCOS is one of the most common causes of female infertility due to irregular ovulation. However, many women with PCOS conceive naturally or with medical assistance. Treatments like letrozole, clomiphene citrate, and IVF can help. Maintaining a healthy weight also significantly improves ovulation regularity.
