Quick answer
Words such as "bulky ovaries" or "PCOD pattern" on a scan report describe how the ovaries look. The international guideline describes this by ovary size and the number of small follicles, and calls it polycystic ovarian morphology. On its own it does not diagnose PCOS: a doctor also looks at your periods and androgens, and rules out other causes.
Tvarvi Key Takeaways
What the words mean
- "Bulky" points to a larger ovary, measured as volume.
- "PCOD pattern" points to many small follicles.
- The small round shapes are follicles, and they are not true cysts.
What the scan cannot do alone
- A scan finding alone is not enough for a PCOS diagnosis.
- Some women with PCOS have normal-looking ovaries.
- Teenagers are not diagnosed with a scan.
What comes next
- A doctor puts the scan together with your periods and symptoms.
- Other causes of similar signs are ruled out first.
- A good report lists the follicle count and ovary size.
In this article
The 2023 International Evidence-based Guideline for PCOS does not use the word "bulky"; it describes a larger ovary by its measured volume. It says polycystic ovarian morphology (PCOM) can be based on too many follicles and/or ovarian enlargement, and sets an ovarian volume of 10 mL or more in at least one ovary as a threshold in adults.
The volume threshold is mainly for certain scans. The guideline recommends using ovarian volume of 10 mL or more, or 10 or more follicles in one cross-section, when older technology or image quality does not allow an accurate count of follicles through the whole ovary.
It also says an abdominal scan should mainly report ovarian volume, because counting follicles across the whole ovary is difficult with that approach. If your report only says "bulky" without a number, you can ask the doctor what volume was measured. For the wider picture of PCOD and PCOS, read our main guide, What is PCOD?
The guideline does not use the term "PCOD pattern"; it describes polycystic ovaries mainly by counting small follicles. It considers the number of follicles per ovary the key ultrasound marker of polycystic ovarian morphology in adults.
The follicles counted are small ones. The guideline's reporting standard asks for the total number of follicles measuring 2 to 9 mm in each ovary, and says a dominant follicle of 10 mm or more should not be included in the volume calculation.
Our page on PCOD vs PCOS explains the two names.
No. A 2026 report for obstetricians and gynaecologists in the American Journal of Obstetrics and Gynecology explains that the typical ovarian appearance reflects numerous arrested antral follicles, which are not pathologic cysts.
This is one reason the condition was renamed. In 2026, a global consensus published in The Lancet named it polyendocrine metabolic ovarian syndrome (PMOS), noting that the term PCOS is inaccurate because it implies pathological ovarian cysts.
The WHO fact sheet on PCOS also states that ovarian cysts are not required for a PCOS diagnosis.
Not on its own. The 2003 Rotterdam consensus concluded that no single criterion, such as high androgens or polycystic ovaries, is sufficient for a clinical diagnosis of PCOS.
The WHO explains that PCOS is diagnosed by at least two of three features, once other causes are excluded: signs or blood tests showing high androgens, irregular or absent periods, and polycystic ovaries on an ultrasound. That also means some women with PCOS have ovaries that look normal on a scan.
Polycystic ovaries without other features may matter little, according to a 2014 report that predates the current guideline. That 2014 task force report from the Androgen Excess and PCOS Society concluded that polycystic ovarian morphology in women who ovulate and show no androgen excess may be inconsequential, though some studies suggest it may be the milder end of the PCOS spectrum.
Table 1. How a scan finding fits into a PCOS diagnosis
| Scan finding | Other features present | What the guideline says |
|---|---|---|
| Polycystic ovaries | Irregular periods or high androgens | Two features present: PCOS may be diagnosed once other causes are excluded |
| Polycystic ovaries | Neither | One feature only: not enough for a diagnosis |
| Normal-looking ovaries | Irregular periods and high androgens | PCOS can still be diagnosed, and a scan is not needed |

For adults, the 2023 guideline sets the threshold for polycystic ovarian morphology at 20 or more follicles in at least one ovary.
Older reports may use a lower number. The 2014 task force report noted that since 2003 most investigators had used a threshold of 12 follicles of 2 to 9 mm per ovary, and described that threshold as now seeming obsolete with newer scanning technology.
The guideline expects these numbers to keep changing. It says thresholds should be revised regularly as ultrasound technology advances, and that age-specific cut-offs should be defined.
The 2023 guideline recommends clear, standardised reporting that includes at least: the last menstrual period or stage of the cycle, the probe frequency, the route of the scan, the total number of 2 to 9 mm follicles per ovary, and the size or volume of each ovary.
The route matters too. The guideline says that when an ultrasound is needed, an internal (transvaginal) scan gives the clearest view of polycystic ovarian morphology, but only if the woman is comfortable with it.
An abdominal scan can be used instead, for example for women who have not been sexually active. The StatPearls clinical reference on gynaecological sonography notes that abdominal ultrasound can be used for young women who have not been sexually active, and the 2023 guideline says an abdominal scan should mainly report ovary volume.
The 2023 guideline states that there are no definitive criteria for polycystic ovarian morphology on ultrasound in adolescents, so it is not recommended for them. It says the diagnosis in adolescents needs both irregular cycles and high androgens.
If you are a teenager and a scan report has worried you, it helps to see a gynaecologist with a parent or guardian. Our article on PCOS in young women covers this age group.
A doctor reads the scan alongside your periods, symptoms and blood tests. The guideline's diagnostic algorithm asks doctors to exclude other causes with tests such as thyroid function (TSH), prolactin, 17-hydroxyprogesterone and FSH.
Sometimes the scan is not needed at all. The 2023 guideline says that when irregular cycles and high androgens are both present, an ovarian ultrasound is not necessary for a PCOS diagnosis, and that an AMH blood test may be used instead of a scan in adults, but not both. Our page on PCOS blood tests explains what each test looks for.
If your report mentions bulky ovaries or a PCOD pattern, a gynaecologist can go through it with you and talk you through what fits your situation.
Can my scan look different at another time of the month? It can. The 2023 guideline asks reports to note the last menstrual period or stage of the cycle, and says a dominant follicle should be left out of the ovary volume.
Is a transvaginal scan needed? Only if a scan is needed and you are comfortable with it. The 2023 guideline calls the transvaginal approach the most accurate for counting follicles, and says an abdominal scan should mainly report ovary volume.
Can I have an AMH test instead of a scan? For adults, the 2023 guideline says an AMH blood test may be used instead of an ultrasound to look for polycystic ovaries, but not both, and never as a single test for PCOS.
Do polycystic ovaries need surgery? The AJOG 2026 report explains that the typical appearance reflects arrested follicles rather than pathologic cysts. A gynaecologist can explain what any other finding on your report means.
