A PCOS quiz can help you reflect on symptoms that may be associated with polycystic ovary syndrome (PCOS), one of the most common hormonal conditions affecting women of reproductive age. Estimates suggest that PCOS affects between 8 and 13 percent of women globally, yet a significant proportion remain undiagnosed.
For a thorough overview of the condition, the PCOS complete guide: symptoms, diagnosis, and treatment covers everything from the Rotterdam diagnostic criteria to management options. PCOS involves a combination of irregular ovulation, elevated androgen levels, and — in some cases — polycystic ovaries on ultrasound. Because symptoms vary widely between individuals, many women live with PCOS for years before receiving a diagnosis.
This quiz is not a diagnostic tool; only a qualified healthcare provider can confirm a PCOS diagnosis. If your responses raise concerns, we encourage you to discuss them with a GP, gynaecologist, or endocrinologist.

What Is PCOS?
Polycystic ovary syndrome (PCOS) is a hormonal disorder characterised by a combination of reproductive, metabolic, and often psychological features. The condition is defined by at least two of three criteria under the widely used Rotterdam consensus: irregular or absent ovulation, biochemical or clinical signs of elevated androgens (male-type hormones such as testosterone), and polycystic ovaries visible on ultrasound.
PCOS is not simply a condition of the ovaries; it is associated with insulin resistance in a substantial proportion of women, which contributes to the metabolic features of the condition including weight gain, difficulty losing weight, and elevated cardiovascular risk over the longer term. The Endocrine Society notes that PCOS is the leading cause of anovulatory infertility in women of reproductive age.
Women with PCOS who are trying to conceive may find the ovulation calculator for irregular cycles helpful for identifying fertile windows when cycles are unpredictable. The exact cause of PCOS is not fully understood, though genetic, environmental, and lifestyle factors are all thought to play a role.
PCOS does not affect all women in the same way: some women experience primarily menstrual and reproductive symptoms, while others are more affected by metabolic or dermatological features. Because PCOS symptoms overlap significantly with other hormonal conditions, taking the hormonal imbalance quiz alongside this assessment can help clarify the broader hormonal picture.
PCOS Symptoms: What to Look For
The symptoms of PCOS are varied and can range from mild to significantly disruptive. Menstrual irregularity is one of the most common presentations: women with PCOS may experience periods that are infrequent, unpredictable, very light, or absent altogether — a pattern explored in detail in irregular periods: causes and when to see a doctor.
Elevated androgen levels can cause hirsutism (excess hair growth on the face, chest, or abdomen), acne that is persistent or cystic particularly along the jawline, and androgenic alopecia (thinning or loss of hair on the scalp). Weight gain and difficulty managing weight — especially abdominal fat accumulation — are associated with the insulin resistance that many women with PCOS experience.
Skin darkening in the form of acanthosis nigricans, appearing as velvety patches on the neck, armpits, or skin folds, is also linked to insulin resistance. Fatigue, low mood, anxiety, and symptoms consistent with depression are reported more frequently among women with PCOS than in the general population. Pelvic pain may occur, though it is more closely associated with conditions such as endometriosis and may indicate a concurrent diagnosis.
Not all women with PCOS will experience all of these symptoms, and symptom severity varies considerably. For those managing PCOS through lifestyle and supplementation, the evidence-based review of PCOS supplements: what the research shows provides practical guidance on which interventions are best supported by clinical evidence.
PCOS Diagnosis: What to Expect at the Doctor
A formal PCOS diagnosis requires a clinical evaluation and cannot be made on the basis of a symptom quiz alone. At an appointment, a healthcare provider will typically take a detailed menstrual and medical history, enquire about symptoms including hair growth, acne, and weight changes, and perform a physical examination.
Blood tests are a key part of the diagnostic process and may include assessment of luteinising hormone (LH), follicle-stimulating hormone (FSH), testosterone and other androgen levels, thyroid function, fasting glucose and insulin, and lipid profile. A transvaginal or pelvic ultrasound may be used to assess ovarian morphology, though the presence of multiple small follicles alone is not sufficient for a diagnosis in the absence of other criteria.
According to ACOG, thyroid disorders, hyperprolactinaemia, and congenital adrenal hyperplasia should be ruled out before a PCOS diagnosis is confirmed, as these conditions can present with similar symptoms. If PCOS is confirmed, management is typically tailored to the individual's primary concerns and may include lifestyle modification, hormonal contraceptives, insulin-sensitising medications, or fertility treatments depending on the person's goals and symptom profile.

Frequently asked questions
Can you have PCOS without irregular periods?
Yes. Although irregular or absent periods are one of the most recognisable features of PCOS, some women with the condition have regular menstrual cycles. Under the Rotterdam diagnostic criteria, PCOS can be diagnosed if a woman meets at least two of three criteria: irregular ovulation, elevated androgens, and polycystic ovaries on ultrasound. A woman may have regular periods but still show biochemical signs of elevated androgens and polycystic ovaries, satisfying the diagnostic threshold. This is sometimes referred to as a non-classic PCOS phenotype. Regular periods do not rule out the condition, which is why clinical evaluation — not a symptom checklist — is essential for an accurate diagnosis.
What causes PCOS?
The precise cause of PCOS is not yet fully understood, and it is likely that multiple interacting factors contribute. Research suggests a strong genetic component: women with a first-degree relative diagnosed with PCOS have a significantly higher risk of developing the condition themselves. Insulin resistance is present in the majority of women with PCOS and is thought to play a central role in driving elevated androgen production by the ovaries. Chronic low-grade inflammation has also been identified as a contributing factor. Environmental influences, including diet, physical activity, and exposure to endocrine-disrupting chemicals, may interact with genetic predisposition to influence symptom severity. No single cause has been identified, and current understanding treats PCOS as a complex, multifactorial condition.
Does PCOS affect fertility?
PCOS is the leading cause of anovulatory infertility, meaning infertility arising from absent or irregular ovulation. However, having PCOS does not mean that conception is impossible. Many women with PCOS conceive naturally, and a range of effective treatments are available for those who require support. First-line approaches for women with PCOS who wish to conceive typically include lifestyle modification to improve insulin sensitivity, which may restore ovulation. Medications such as letrozole or clomiphene citrate may be used to induce ovulation when lifestyle measures alone are insufficient. In vitro fertilisation (IVF) is also an option for women who do not respond to ovulation induction. ACOG recommends that women with PCOS who are trying to conceive seek specialist care from a reproductive endocrinologist for personalised assessment and management.
Can PCOS be managed without medication?
For some women, particularly those whose primary concerns are metabolic and where symptoms are mild, lifestyle modification can meaningfully improve PCOS symptoms without medication. Research suggests that a loss of 5–10 percent of body weight in overweight or obese women with PCOS can restore ovulation, improve menstrual regularity, reduce androgen levels, and improve insulin sensitivity. Regular physical activity — including both aerobic exercise and resistance training — is associated with improvements in insulin resistance and hormonal profiles in women with PCOS. Dietary approaches that reduce refined carbohydrates and added sugars may also help manage insulin levels. However, for many women — including those who are of healthy weight, those seeking contraception, or those with more severe hormonal symptoms — medication remains an important and effective part of management. A healthcare provider can help determine the most appropriate approach based on individual circumstances.
