Diagnosing POMS : from suspicion to confirmation
Updated on
August 6, 2026
Receiving a suspected POMS diagnosis raises a valid question: is it really this syndrome, and is the assessment complete? A POMS diagnosis is based on a combination of criteria, not a single test. Understanding what makes up a thorough assessment helps you approach your care with greater clarity.
Key points
- POMS is diagnosed using the Rotterdam criteria: 2 out of 3 criteria are sufficient; you do not need all three.
- A complete hormonal panel is essential: it must be performed between days 2 and 5 of your cycle, while not on any hormonal contraception.
- According to the 2023 ESHRE/Monash guidelines, an AMH (anti-Müllerian hormone) test can now replace a pelvic ultrasound for adult women.
- A differential diagnosis is necessary to rule out other conditions with similar symptoms, such as hypothyroidism, hyperprolactinemia, or congenital adrenal hyperplasia.
The Rotterdam criteria: how POMS is diagnosed
POMS is diagnosed according to the Rotterdam criteria, defined by international consensus and updated in 2023. There are three such criteria:
- Cycle irregularities : persistent irregular or absent cycles (fewer than 8 cycles per year, or cycles longer than 35 days)
- Hyperandrogenism : an excess of androgen hormones, detected clinically (acne, hirsutism, androgenic alopecia) or biologically (high blood levels)
- Polycystic ovarian morphology : at least 20 follicles under 9 mm per ovary, or an ovarian volume greater than 10 mL on ultrasound
Two out of three criteria are sufficient. A woman with irregular cycles and biochemical hyperandrogenism can be diagnosed without characteristic ultrasound findings, and vice versa.
The 2023 ESHRE/Monash guidelines introduce an important update: AMH testing (anti-Müllerian hormone) can now replace pelvic ultrasound to assess ovarian morphology in adult women. This option is relevant for patients who do not wish to or cannot undergo a transvaginal ultrasound.

Regarding diagnosis in adolescents: the Rotterdam criteria do not apply directly before the end of pubertal maturation. Menstrual irregularities are physiological during the first few years following menarche. A specialist consultation is necessary to distinguish normal pubertal development from a clinical picture that warrants investigation.
What a well-conducted assessment includes
A comprehensive POMS assessment consists of three components. Performing them together is essential for a reliable diagnosis.
The three components are as follows:

Differential diagnosis: why rule out other causes
Several conditions produce symptoms similar to those of POMS. Identifying their absence is a necessary step, not just a formality: some of these conditions require specific management that is very different from that of POMS.
The four priority conditions to investigate:
- Hypothyroidism : menstrual irregularities, fatigue, weight gain; a TSH test is sufficient to identify or rule it out
- Hyperprolactinemia (excess prolactin, often linked to a pituitary adenoma): amenorrhea, menstrual irregularities, sometimes galactorrhea; a prolactin test is part of the standard workup
- Late-onset congenital adrenal hyperplasia (CAH) : marked hyperandrogenism, severe hirsutism, resistant acne; a 17-OHP test helps distinguish it from POMS
- Cushing's syndrome : hypercortisolism, rapid weight gain, high blood pressure; rarer, to be considered in severe or atypical cases
An incomplete differential diagnosis can lead to starting treatment for POMS when another condition is actually the cause. This is precisely where an expert review of your medical file is invaluable.

Frequently Asked Questions
How is POMS diagnosed?
POMS is diagnosed using the Rotterdam criteria: 2 out of 3 criteria are sufficient (menstrual irregularities, hyperandrogenism, polycystic ovarian morphology). The diagnosis is based on a combination of clinical examination, hormonal assessment, and imaging or AMH testing.
What tests are needed to confirm POMS?
A comprehensive assessment includes hormonal testing (testosterone, LH/FSH, TSH, prolactin, 17-OHP), a pelvic ultrasound or AMH test, and a metabolic panel (blood glucose, insulin, lipids). To ensure accuracy, these tests must be performed while not using hormonal contraception.
Can you have POMS without cysts on an ultrasound?
Yes: the images seen on an ultrasound are immature follicles, not pathological cysts, and their absence does not rule out the diagnosis. Two out of three criteria are sufficient: irregular cycles and hyperandrogenism are enough to confirm POMS without ultrasound findings.
Is an AMH test enough to diagnose POMS ?
According to the 2023 ESHRE/Monash guidelines, an AMH test can replace an ultrasound to assess ovarian morphology, but it is not sufficient on its own to diagnose POMS. It is part of a comprehensive assessment that also includes hormonal testing and clinical evaluation.
At what age can POMS be diagnosed in adolescents?
Diagnosis in adolescents follows specific criteria that differ from those for adult women, as menstrual irregularities are physiological during the first few years after puberty. A specialist consultation is recommended to distinguish normal pubertal development from signs that warrant further investigation.

Did you know?
The Rotterdam criteria were established in 2003 during an ESHRE/ASRM consensus. The 2023 ESHRE/Monash guidelines updated them by incorporating AMH as an alternative to ultrasound. This update has not yet been uniformly integrated into frontline practice, which may explain some disparities in the assessments received.
A hormonal assessment performed while on hormonal contraception cannot be used to diagnose POMS: synthetic estrogens alter LH, FSH, and androgen levels, making the results uninterpretable. Ameli.fr recommends a sufficient washout period before any diagnostic blood work.
It is ideally performed between days 2 and 5 of the cycle, while not on any hormonal contraception. A break of at least 3 months is generally necessary to allow for reliable interpretation of the results. It includes:
- Total and/or free testosterone
- Androstenedione and DHEAS (dehydroepiandrosterone sulfate)
- 17-hydroxyprogesterone (17-OHP): used to rule out congenital adrenal hyperplasia
- LH and FSH: a high LH/FSH ratio is common in POMS, though not specific
- Prolactin and TSH: components of the differential diagnosis, to be included systematically
Pelvic ultrasound (preferably endovaginal for better resolution) or, as of 2023, AMH testing as a validated alternative.
It evaluates the insulin-resistant component, which is central to the POMS diagnosis:
- Fasting blood glucose
- Oral glucose tolerance test (OGTT)
- Fasting insulin
- Lipid profile (total cholesterol, HDL, LDL, triglycerides)
