PCOS and Fertility, Explained
What the diagnosis means, how it’s treated, and why PCOS is now called PMOS.
Have Questions About PCOS or Fertility?
Meet with one of SpringCreek’s fertility specialists to talk through diagnosis and treatment.
Polycystic ovary syndrome, now called PMOS, is one of the most common reasons people seek fertility care, and it is also one of the most treatable.
In May 2026, the condition’s name officially changed from PCOS to PMOS, polyendocrine metabolic ovarian syndrome. The diagnosis, the treatments, and your options haven’t changed. Only the name has. Here’s what that means, and what to know about PCOS and fertility either way.
THE SHORT ANSWER
What PCOS (Now PMOS) Actually Is
PMOS is a hormonal and metabolic condition that can affect ovulation, and it’s one of the most common reasons people seek fertility care. The new name reflects what specialists have understood for years: it’s not just about the ovaries, it’s a broader hormonal and metabolic picture.
- Not everyone with PMOS has the same symptoms, and the condition is diagnosed using a set of criteria, not a single test.
- PMOS can disrupt ovulation, which is the main way it affects fertility, but ovulation can often be supported with treatment.
- A diagnosis of PCOS or PMOS does not mean pregnancy is out of reach. It means your care plan should be built around your specific hormone and metabolic picture.
WHAT’S CHANGING
Why PCOS Is Now Called PMOS
On May 12, 2026, a global coalition of more than 50 patient and professional organizations announced that polycystic ovary syndrome (PCOS) would be renamed polyendocrine metabolic ovarian syndrome (PMOS). Here is what that change actually involved.
1. The new name
Polycystic ovary syndrome (PCOS) is now officially called polyendocrine metabolic ovarian syndrome (PMOS).
2. When it happened
The change was announced May 12, 2026, following a 14-year global research and consensus process.
3. Who’s behind it
More than 50 patient and professional organizations took part, including the American Society for Reproductive Medicine (ASRM) and the Endocrine Society.
4. Where it was published
The consensus was published in The Lancet, based on survey responses from roughly 22,000 patients and health professionals worldwide.
5. Why the name changed
PCOS focused attention on ovarian cysts that many patients don’t actually have. PMOS reflects the condition’s real hormonal and metabolic scope.
6. What it means for your care
Nothing about your diagnosis or treatment changes. Both names may appear in your records and conversations during a three-year transition period.
WHY IT MATTERS
The Name Changed. Your Options Didn’t.
Whether your chart says PCOS or PMOS, the diagnosis and the path forward are the same. The renaming doesn’t add new criteria or change what treatment can do for you.
- Ovulation-supporting treatment, including medication, IUI, or IVF, is the same set of tools used before and after the rename.
- If you were diagnosed with PCOS, your diagnosis stands. You don’t need to be retested or relabeled to keep your current care plan.
- Both terms will likely appear in your records, conversations, and online sources for the next few years, so don’t be surprised to see either one.
This is exactly why the name change matters less for your treatment and more for how the condition is understood going forward. What matters for you is the same as it’s always been: a plan built around your own hormone and metabolic picture.
THE BIGGER PICTURE
Is PCOS the Same as PMOS?
Yes. PMOS is the new name for the condition previously called PCOS. Nothing about the underlying diagnosis changed, only the terminology used to describe it.
If you’re newly exploring symptoms, a fertility specialist can review your history, hormone levels, and ultrasound findings to confirm or rule out PMOS, using the same diagnostic approach used for PCOS.
QUESTIONS TO ASK ABOUT PCOS AND PMOS
- Do I meet the diagnostic criteria for PMOS, and what did that assessment involve?
- How is PMOS specifically affecting my ovulation and fertility?
- What treatment options fit my specific hormone and metabolic picture?
- Will my existing PCOS diagnosis and records carry over under the new name?
- What can I expect during the transition between PCOS and PMOS terminology?
WHAT TO EXPECT
Signs You’re Getting Care Built Around You
✓ A diagnosis based on your specific history, hormones, and ultrasound, not assumptions.
✓ A treatment plan that addresses hormone and metabolic health, not just ovulation.
✓ Clear, current information about PMOS, not outdated PCOS-only framing.
✓ A specialist who explains your options rather than defaulting to one path.
✓ Support that treats fertility as part of your overall health, not separate from it.
Signs to Look Into Further
✕ A diagnosis based on a single symptom or test, rather than the full criteria.
✕ Treatment that only addresses ovulation and ignores metabolic health.
✕ Outdated information that hasn’t caught up with the PMOS terminology.
✕ A one-size-fits-all treatment plan regardless of your specific picture.
✕ No clear explanation of what your diagnosis actually means for your options.
COMMON QUESTIONS
Frequently Asked Questions
Q. Is PCOS the same as PMOS?
A. Yes. Polyendocrine metabolic ovarian syndrome (PMOS) is the new name for the condition previously called polycystic ovary syndrome (PCOS). The diagnosis and treatment options are unchanged. Only the name is different.
Q. When and why did PCOS get renamed to PMOS?
A. The name changed on May 12, 2026, following a 14-year global research and consensus process published in The Lancet, endorsed by more than 50 organizations including ASRM and the Endocrine Society. The new name reflects the condition’s hormonal and metabolic scope, rather than focusing on ovarian cysts many patients don’t actually have.
Q. Does PCOS (PMOS) mean I can’t get pregnant?
A. No. PMOS can disrupt ovulation, which can make conceiving harder, but ovulation can often be supported with treatment, including medication, IUI, or IVF. It’s a highly treatable cause of fertility challenges.
Q. How is PMOS diagnosed?
A. PMOS is diagnosed using established criteria that consider ovulation patterns, signs of elevated androgens, and ovarian appearance on ultrasound, after other conditions are ruled out. A fertility specialist reviews your full history to confirm it.
Q. How is PMOS treated?
A. Treatment depends on your goals. For fertility, that often starts with supporting regular ovulation through lifestyle changes and medication, and can include IUI or IVF if needed. Your plan is built around your specific situation.
Q. Will my old PCOS diagnosis still count?
A. Yes. If you were diagnosed with PCOS, that diagnosis carries over under the new name. You don’t need to be retested to continue your current care plan.
Q. Will I see both PCOS and PMOS used at the same time?
A. Yes, likely for the next few years. The transition to PMOS is expected to take about three years, so both terms may appear in your records, conversations, and online sources during that time.
