PCOS Has a New Name: PMOS

For years, many people diagnosed with polycystic ovary syndrome, or PCOS, have felt that the name did not fully describe what they were experiencing. The term often led people to focus mainly on “cysts” in the ovaries, even though PCOS is much more than an ovarian condition. It can affect hormones, metabolism, ovulation, fertility, skin, weight, insulin resistance, emotional well-being, and long-term health.

A new article published in The Lancet introduces a major global shift: PCOS is being renamed polyendocrine metabolic ovarian syndrome, or PMOS. The change comes after a large international consensus process involving patients, clinicians, researchers, and advocacy groups. The goal is to create a name that more accurately reflects the condition and supports better awareness, diagnosis, care, and research.

NewYork-Presbyterian’s Health Matters article explains that this change is not just about replacing letters in a name. It is about correcting a long-standing misunderstanding. As Dr. Rekha Kumar, an endocrinologist at NewYork-Presbyterian/Weill Cornell Medical Center, explains, PMOS is “not a condition defined by ovarian cysts.” It is a complex condition that can affect reproductive health, metabolic health, mental health, skin health, and more.

Why Was PCOS Renamed?

The name “polycystic ovary syndrome” has long been considered misleading. The word “cystic” suggests that the condition is mainly about ovarian cysts, but the so-called “cysts” seen on ultrasound are not pathological cysts. They are actually immature follicles.

This misunderstanding matters because it can affect diagnosis. Some people may be told they do not have PCOS because their ultrasound does not show ovarian cysts, even though they may have irregular periods, signs of excess androgens, insulin resistance, or other symptoms connected to the condition.

The NewYork-Presbyterian article highlights this concern clearly. Dr. Kumar notes that many women have been told their ultrasound looks normal and therefore they do not have PCOS, even though ovarian appearance is only one part of the diagnosis.

The new name, polyendocrine metabolic ovarian syndrome, helps shift attention to the full picture.

What Does PMOS Mean?

The new name breaks down into three important parts:

Polyendocrine means that more than one hormonal system may be involved. PMOS is not simply an ovarian issue. It can involve interactions between insulin, androgens, reproductive hormones, and other endocrine pathways.

Metabolic recognizes that metabolic health is central to the condition. Many people with PCOS/PMOS experience insulin resistance, which can influence weight, blood sugar, cholesterol, blood pressure, fertility, and long-term health.

Ovarian keeps the connection to ovulation and ovarian function, which remain important parts of the syndrome. Irregular ovulation, menstrual cycle changes, and fertility concerns are still central for many people affected by the condition.

In other words, PMOS gives a more complete picture: this is a hormonal, metabolic, and reproductive health condition—not simply a “cyst” condition.

How Common Is PMOS?

According to the NewYork-Presbyterian article, PMOS affects approximately one in eight women, or more than 170 million people worldwide. It often appears during the reproductive years and may begin around puberty or early adulthood. However, many people are not diagnosed until they are trying to conceive and begin experiencing fertility challenges.

That delay is one of the major reasons the name change matters. When the condition is framed too narrowly as a gynecological or ovarian issue, the broader hormonal and metabolic signs may be missed.

Common Signs and Symptoms of PMOS

PMOS can look different from person to person. Some people may have visible symptoms, while others may have symptoms that are easier to overlook.

Common signs may include:

• Irregular or absent periods
• Infrequent or absent ovulation
• Acne
• Excess facial or body hair growth
• Hair thinning or androgenic alopecia
• Ovarian follicles visible on ultrasound
• Weight gain or difficulty managing weight
• Insulin resistance
• Abnormal cholesterol or lipid levels
• Elevated blood pressure
• Anxiety or depression

The NewYork-Presbyterian article explains that PMOS is often underdiagnosed because it does not look the same in every woman. For example, someone who is lean, has irregular periods, but does not have obvious excess hair growth may not fit the common stereotype and may therefore be missed.

Why the New Name May Improve Care

Names shape how conditions are understood. When a condition is poorly named, it can delay diagnosis, minimize symptoms, and fragment care.

For example, if PCOS is seen only as an ovarian issue, care may focus mainly on periods, fertility, or ultrasound findings. But PMOS encourages a broader view—one that includes insulin resistance, glucose levels, lipid levels, blood pressure, mental health, dermatology, fertility, and long-term metabolic risk.

Dr. Kumar explains that treatment is often too narrowly focused on the most obvious symptom. If someone is trying to get pregnant, care may focus only on fertility. If someone has acne, care may focus only on skin symptoms. But PMOS calls for a more complete approach that considers the whole person.

Can PMOS Be Managed?

PMOS is considered a lifelong condition, but that does not mean people are powerless. As Dr. Kumar says in the NewYork-Presbyterian article, “lifelong” does not mean “untreatable.” Symptoms can often be improved, metabolic risks can be reduced, and fertility outcomes may be supported with the right care.

Management may include lifestyle medicine, nutrition strategies, metabolic screening, medications when appropriate, fertility support, and ongoing care from clinicians who understand both the reproductive and metabolic aspects of the condition.

Anyone who suspects they may have PMOS should speak with a qualified healthcare provider. A thorough evaluation may include menstrual history, signs of androgen excess, blood work, metabolic testing, and ultrasound when appropriate.

What This Means for Women, Families, and Birth Workers

For doulas, childbirth educators, lactation professionals, and postpartum care providers, this change is worth understanding.

Many people with PCOS/PMOS may come into pregnancy, birth, or postpartum with a history of irregular cycles, fertility treatment, insulin resistance, gestational diabetes risk, body image concerns, anxiety, or previous experiences of not being heard by the medical system.

While doulas do not diagnose or treat PMOS, they can provide informed, compassionate, nonjudgmental support. This may include:

• Helping clients feel heard when they share their reproductive or hormonal health history
• Encouraging clients to discuss symptoms or concerns with their healthcare provider
• Being mindful of the emotional impact of fertility challenges or pregnancy complications
• Supporting postpartum recovery with rest, nourishment, practical care, and referrals when needed
• Using updated, respectful language as terminology evolves

This is also a reminder that reproductive health conditions are often whole-body conditions. A client’s experience is not limited to one symptom, one diagnosis, or one part of the body.

What Should Someone Do If They Suspect PMOS?

One of the strongest messages from the NewYork-Presbyterian article is simple: “Advocate for yourself.” Dr. Kumar encourages people not to let a normal ultrasound be the end of the conversation if they continue to experience symptoms.

A person may want to ask their provider about:

• Irregular periods or ovulation concerns
• Acne, excess hair growth, or hair thinning
• Blood sugar, insulin, and glucose testing
• Lipid panel or cholesterol screening
• Blood pressure and cardiometabolic risk
• Fertility concerns
• Anxiety, depression, or emotional well-being

For some people, seeing an endocrinologist, reproductive endocrinologist, or clinician with metabolic health expertise may be helpful.

Will Everyone Start Saying PMOS Right Away?

Probably not immediately. The transition from PCOS to PMOS will take time. Many patients, clinicians, educators, insurance systems, electronic health records, and public health resources still use the term PCOS.

For now, people may see both terms used together: PCOS, now renamed PMOS, or PCOS/PMOS. This transition period can help maintain continuity while allowing the more accurate name to become familiar.

A More Accurate Name Can Lead to Better Care

The renaming of PCOS to PMOS is more than a terminology update. It is a shift in how the condition is understood.

For people living with this condition, the new name may feel validating. It acknowledges that their symptoms are not “just ovarian,” not “just cosmetic,” and not “just fertility-related.” PMOS recognizes the broader endocrine and metabolic reality of the condition.

For health professionals and care providers, it is an opportunity to improve education, communication, and support.

And for doulas and maternal health professionals, it is a reminder to stay informed, use language thoughtfully, and support clients as whole people—with bodies, hormones, histories, emotions, and lived experiences that deserve to be understood.
