PCOS Symptom Checker

Symptom screening based on the Rotterdam criteria — to prepare a focused conversation with your gynecologist.

Cycle & ovulation

Irregular cycles (longer than 35 or shorter than 21 days)
Missed periods (3 or more in a row)

Hyperandrogenic signs

Excess body hair (hirsutism — face, chest, abdomen)
Persistent adult acne (face, chest, back)
Scalp hair thinning (androgenic alopecia)

Metabolic & other clues

Weight gain or central obesity despite stable lifestyle
Dark velvety patches in skin folds (acanthosis nigricans)
Trouble conceiving for over 12 months
PCOS or type 2 diabetes in close family

Rotterdam criteria (2 of 3 needed for PCOS diagnosis)

  • 1. Ovulatory dysfunction (oligo- or anovulation)
  • 2. Hyperandrogenism (clinical or biochemical)
  • 3. Polycystic ovaries on ultrasound

    Criterion 3 requires ultrasound imaging by a clinician — this calculator cannot replace it.

How it works

This tool maps to the Rotterdam criteria (ESHRE/ASRM 2003): a PCOS diagnosis needs 2 of 3 — ovulatory dysfunction, clinical or biochemical hyperandrogenism, and polycystic ovaries on ultrasound. Your inputs estimate the first two criteria; the ultrasound stays with your clinician. Supporting symptoms (acanthosis nigricans, weight gain, fertility issues, family history) raise the suspicion score. The result is orientation, not a diagnosis.

This calculator does not replace medical evaluation. If PCOS is suspected, consult a gynecologist or endocrinologist — therapy and lifestyle measures are often very effective.

Frequently Asked Questions

What is PCOS?+
Polycystic ovary syndrome (PCOS) is a hormonal disorder with elevated androgens, ovulatory dysfunction and often polycystic ovaries. It is the most common endocrine disorder in women of reproductive age, affecting roughly 5–10 %.
What are the Rotterdam criteria?+
The Rotterdam criteria (ESHRE/ASRM 2003) are the international standard for PCOS diagnosis. Two of three are required: ovulatory dysfunction, hyperandrogenism (clinical or biochemical), and polycystic ovaries on ultrasound.
What is hirsutism?+
Hirsutism is excess male-pattern terminal hair in women — face, chest, abdomen, back. It is graded clinically with the modified Ferriman-Gallwey score; values of 8 or higher are considered abnormal.
Which lab tests are used in PCOS work-up?+
Standard hormones: total and free testosterone, SHBG, DHEAS, androstenedione, LH, FSH, estradiol, prolactin, TSH, optionally 17-OH-progesterone. Metabolic: fasting insulin, HbA1c and an oral glucose tolerance test for insulin resistance.
Can you get pregnant with PCOS?+
Yes — most women with PCOS can have children, though support is often needed. Effective options include lifestyle change (weight), metformin, letrozole or clomiphene for ovulation induction, and assisted reproduction (IVF) when indicated.
What helps with PCOS?+
Lifestyle changes have the biggest effect: a 5–10 % weight loss often restores cycles and lowers androgens. Pharmacology: metformin (insulin resistance), combined pill (cycle regulation, acne, hirsutism), spironolactone (antiandrogen), and inositol as a supplement.
