PCOS officially renamed PMOS to improve women’s health diagnosis

One of the most common hormonal disorders affecting women has officially received a new name in a landmark step for women’s healthcare. Polycystic Ovary Syndrome (PCOS) will now be known as Polyendocrine Metabolic Ovarian Syndrome (PMOS), reflecting the condition’s broader impact on the body and addressing long-standing concerns that the previous name was misleading.

Medical experts say the change is more than cosmetic. The former name focused primarily on the ovaries and the presence of “polycystic” ovaries, even though many patients do not develop ovarian cysts. More importantly, it failed to recognize that the condition affects multiple body systems, including hormones, metabolism, mental health, skin, and reproductive health. (ASRM⁠)

The decision follows years of international collaboration involving healthcare professionals, researchers, and women living with the condition. More than 50 medical and patient organizations contributed to the global consensus, with the goal of adopting terminology that better represents the complexity of the disorder. (Endocrine⁠)

PMOS affects approximately one in eight women worldwide, making it one of the most common endocrine disorders among women of reproductive age. Symptoms can include irregular menstrual cycles, acne, excessive hair growth, weight changes, fertility challenges, and insulin resistance. Because symptoms vary widely, many women experience delays in receiving an accurate diagnosis. Experts hope the updated name will encourage earlier recognition and more comprehensive medical care.

Researchers also believe the new terminology will improve public awareness by emphasizing that the condition extends far beyond reproductive health. It highlights the important role of metabolic and endocrine factors, helping both patients and healthcare providers better understand the disorder and its long-term health implications.

Importantly, while the name has changed, the condition itself has not. Existing diagnostic guidelines and treatment approaches remain in place, although future medical literature and international guidelines will gradually adopt the term PMOS. (Monash University⁠)

Health advocates have welcomed the decision as a significant milestone for women’s health. They hope the new name will reduce misconceptions, improve diagnosis rates, encourage further research, and ensure millions of women receive timely, accurate care.

For patients around the world, the transition from PCOS to PMOS represents more than a new medical term—it signals a broader understanding of a complex condition and a renewed commitment to improving women’s healthcare. (Monash University⁠)
