A major change has been announced in women’s health care as polycystic ovary syndrome, commonly known as PCOS, has officially been renamed polyendocrine metabolic ovarian syndrome, or PMOS. Medical experts behind the decision say the old name did not correctly explain the condition and often confused both patients and doctors.

PCOS affects nearly one in eight women around the world. For years, doctors and researchers argued that the name focused too much on ovarian “cysts” even though most women with the condition do not actually have true cysts in their ovaries. Experts now believe the new name better reflects the hormonal, metabolic and reproductive problems linked to the condition.

The decision to rename PCOS was not made quickly. Researchers, doctors, healthcare workers and patient groups from many countries were involved in discussions over several years. Experts said the aim was to choose a name that was medically accurate and easier for people to understand.

Dr Helena Teede, an endocrinologist and professor of women’s health at Monash University in Australia, said the old name created confusion because it highlighted one feature that was not even necessary for diagnosis.

She explained that the condition affects many parts of the body, not only the ovaries. According to experts, women with PMOS may face hormonal imbalance, weight problems, irregular periods, acne, fertility issues, insulin resistance and mental health challenges.

Experts also pointed out that the word “polycystic” often frightened patients because it made them think they had dangerous ovarian cysts. However, researchers say the structures seen in the ovaries are usually not harmful cysts.

Why doctors changed the name

Doctors explained that when the condition was first identified in the 1930s, medical science was limited. During surgeries, doctors noticed ovaries that looked uneven and contained small fluid-filled structures. At that time, these were believed to be cysts.

However, researchers now understand that these are actually immature egg follicles that stop developing properly because of hormonal imbalance. Experts call them “arrested follicles.”

Dr Teede said true ovarian cysts behave differently. They can grow larger, rupture, bleed or sometimes require surgery. Women with PMOS are not necessarily more likely to develop these dangerous cysts.

Because of this, experts felt the word “polycystic” was medically incorrect and misleading.

The debate about changing the name has existed for many years. In 2012, experts from the US National Institutes of Health also stated that the term PCOS created confusion for both doctors and patients.

Researchers said the old name focused on ovarian appearance instead of the real health problems linked to the condition. They explained that many women with PMOS may not even show the classic ovarian appearance on ultrasound scans, yet they still suffer from the disorder.

The new term “polyendocrine metabolic ovarian syndrome” was chosen carefully after discussions with doctors and patients worldwide.

The word “polyendocrine” refers to the condition affecting several hormone systems in the body. “Metabolic” highlights the impact on metabolism, weight control and insulin resistance. “Ovarian” was included because the ovaries remain an important part of the condition.

Experts said the new name better explains the full picture of the disorder instead of focusing only on ovarian appearance.

Thousands of healthcare professionals and patients took part in surveys during the renaming process. Around 56 medical, academic and patient organisations were involved in reviewing and approving the decision.

Researchers also created a three-year plan to slowly introduce the new term into hospitals, clinics, awareness campaigns and educational materials.

Dr Teede said the process was transparent and included opinions from many communities and patient groups around the world.

PMOS affects more than fertility

Experts stressed that PMOS is not only a reproductive condition. It can affect many areas of health and daily life.

Women with PMOS may experience irregular menstrual cycles, difficulty losing weight, acne, excessive hair growth, hair thinning and fertility problems. Some also struggle with anxiety, depression and low confidence because of the condition’s symptoms.

Doctors say insulin resistance is one of the major problems linked to PMOS. In this condition, the body struggles to use insulin properly, which can increase the risk of diabetes and obesity.

Experts believe the new name will help patients understand that PMOS is a full-body hormonal and metabolic disorder rather than simply an ovarian disease.

Researchers also discussed whether to keep the familiar abbreviation “PCOS” to make the transition easier. However, most people involved in the surveys preferred accuracy over convenience.

The term “ovarian” also created debate because some experts worried it might increase social pressure related to fertility. In many cultures, women are judged based on their ability to have children.

Dr Teede explained that using words linked to fertility can sometimes emotionally hurt women who are already dealing with health challenges. However, she added that many women with PMOS can still become pregnant with proper treatment and medical care.

Doctors stressed that early diagnosis and treatment are very important. Many symptoms can be managed through healthy eating, exercise, weight management and medications.

Researchers are also reviewing other medical terms connected to the condition. For example, ultrasound findings currently described as “polycystic ovarian morphology” may eventually receive new terminology that better matches the updated understanding of the disorder.

Some researchers have even discussed whether men may experience a similar hormonal and metabolic condition. Certain men show symptoms such as insulin resistance, obesity, low hormone levels and hair problems. However, experts say there is still not enough scientific evidence to call it a male version of PMOS.

Doctors believe the renaming of PCOS to PMOS could improve awareness and help patients receive faster and more accurate treatment. Experts hope the new name will reduce confusion and encourage more people to understand the condition properly.

They also believe the change will help patients feel less anxious about the word “cyst” and focus more on managing the hormonal and metabolic aspects of the disorder.
