PCOS is now PMOS. And it's long overdue.
For decades, millions of women were told they had a problem with cysts on their ovaries. Except there is no increase in abnormal ovarian cysts in this condition. The name was wrong from the start, and that single inaccuracy contributed to years of missed diagnoses, fragmented care, and stigma.
Polyendocrine Metabolic Ovarian Syndrome (PMOS) is the new name for the condition previously known as PCOS. The new name, published in The Lancet on May 12, reflects the broader polyendocrine disturbances occurring in women's insulin, androgens, neuroendocrine, and ovarian hormones, and the metabolic impacts these have on their lives.
This rename was led by Professor Helena Teede of Monash University. After hearing from 22,000 people over 11 years, including doctors, researchers, patients, and advocacy organizations, the new name was chosen with priorities of stigma avoidance, scientific accuracy, and ease of communication. Women's lived experience was baked into this process from the beginning.
What the name actually tells us:
PMOS affects 1 in 8 women, yet remains dramatically underdiagnosed, particularly in Black and African American patients, who face a 69% higher rate of missed diagnosis than white patients.
Each letter in PMOS matters:
Poly-endocrine: Multiple hormone systems are involved, including androgens, insulin, and neuroendocrine signaling
Metabolic: Insulin resistance is a hallmark feature
Ovarian: Irregular cycles, anovulation, and fertility challenges
Syndrome: It looks different in every patient
The reach of PMOS goes well beyond the ovaries. It affects reproductive health, metabolic health, cardiovascular health, dermatological health (acne, excess hair), and mental health.
How acupuncture and Chinese medicine can help:
This is where integrative medicine has something genuinely important to offer. Research shows that acupuncture works on several of the core mechanisms driving PMOS:
Hormonal regulation: Acupuncture elevates beta-endorphin levels in both the central nervous system and peripheral circulation, which modulates GnRH and LH release, two key hormones disrupted in PMOS.
Nervous system balance: Abnormal sympathetic nervous activity in the ovaries is part of how PMOS develops. Acupuncture can inhibit the overexpression of nerve growth factor (NGF), reduce that excess sympathetic tone, and help restore normal ovarian hormone response.
Insulin sensitivity: One of the most promising findings: acupuncture influences the phosphorylation of insulin receptors and downstream signaling pathways, directly addressing the insulin resistance that is central to PMOS.
Lipid and metabolic function: Research also points to acupuncture's role in improving cholesterol metabolism, inhibiting excess fatty acid synthesis, and promoting healthy energy metabolism.
Chinese medicine has always understood this condition as a whole-body pattern, not an isolated ovarian problem. The new name finally catches up to that understanding.
If you wonder whether PMOS might affect you, ask your doctor for:
Comprehensive hormone testing, not just an ultrasound
Metabolic screening: fasting insulin, fasting glucose, A1C
Cardiovascular and mental health evaluation alongside reproductive symptoms
Whole-body care across specialties
For every woman who was told it was "just your hormones" or sent home without answers: this rename is for you. And so is this clinic.
