There has been global coverage highlighting the transition from Polycystic Ovary Syndrome (PCOS) to Polyendocrine Metabolic Ovarian Syndrome (PMOS) and many patients have been left wondering what this name change means for their diagnosis, fertility treatment, and long-term wellbeing. For years, the term "Polycystic Ovary Syndrome" has caused unnecessary confusion. The name implies that patients suffer from dangerous cysts on their ovaries. Those "cysts" are actually completely natural, healthy fluid-filled follicles that have under-developed due to hormonal imbalances. By updating the medical terminology to Polyendocrine Metabolic Ovarian Syndrome (PMOS), we are finally calling this condition what it truly is: a systemic hormonal and metabolic condition.

Why is PCOS being renamed to PMOS?

The term PCOS has been a misleading description, which is finally being corrected. PCOS isn’t about the ovaries, it’s about a patient's endocrine and metabolic systems. Whereas PMOS can affect almost every aspect of a sufferer's daily life and long-term health, including:
  • Insulin resistance and how the body processes sugar
  • Hormonal fluctuations and ovulatory function
  • Weight management and metabolic rate
  • Long-term cardiovascular health risks
We hope this new name brings comfort to our patients. It proves that daily struggles like fatigue, weight changes, and irregular cycles aren't separate, confusing issues. Instead, they all stem from how your body's energy system works.

PCOS vs. PMOS: Our stance at Herts & Essex Fertility Centre

While we are in full support of using the medical term Polyendocrine Metabolic Ovarian Syndrome to give our patients a more accurate framework for their medical treatment, we also recognise that sufferers have spent years finding answers, seeking fertility advice, and building supportive communities under the banner of PCOS. For that reason, we will use both terms of PCOS and PMOS in our daily conversations to ensure our patients can find the help, resources, and community they need online and in person. Our priority is to ensure our patients always feel connected to the community they know. We are updating the science to provide better care, but we are keeping the conversation accessible, familiar, and empathetic for the people who matter most: the patients.

Frequently asked questions about the PMOS name change

What does PMOS stand for? PMOS stands for Polyendocrine Metabolic Ovarian Syndrome. It’s the updated medical term for the condition previously known as PCOS (Polycystic Ovary Syndrome). Do I have cysts if I am diagnosed with PMOS? No. Despite the old name "Polycystic Ovary Syndrome," the condition does not cause actual ovarian cysts. Instead, a scan typically shows an increased number of small, harmless, natural follicles that have stayed small due to hormone imbalances. Will my fertility treatment change with the new PMOS name? The name change itself doesn’t alter your care. It will allow fertility specialists to build more comprehensive treatment plans that address both reproductive health and underlying metabolic factors like insulin resistance.]]> Day 12 – Advent Calendar 2025 https://hertsandessexfertility.com/day-12-advent-calendar-2025/ Wed, 24 Dec 2025 07:00:07 +0000 https://hertsandessexfertility.com/?p=6448 Our Baby Advent Calendar features our 2025 babies, highlights from our little visitors who popped in to the clinic for cuddles, our annual baby party in the summer and more! ...
