PMOS and your fertility! Why metabolic health matters!
Polycystic ovary syndrome (PCOS) has been renamed polyendocrine metabolic ovarian syndrome (PMOS). Announced in May 2026, the new name better reflects the hormonal, metabolic and reproductive aspects of the condition. You may still see both names during the transition. Endocrine Society.
The old name placed too much emphasis on ovarian “cysts”, overlooking the broader effects on a woman’s health.
The new name recognises:
Polyendocrine, meaning multiple hormonal pathways are involved.
Metabolic: insulin action and blood sugar regulation are important parts of the condition.
Ovarian syndrome: the ovaries are involved, but they are one part of a bigger picture.
Why metabolic health matters
Insulin resistance is a key feature of PMOS. This means the body responds less effectively to insulin, the hormone that helps regulate blood sugar. Supporting metabolic health deserves attention alongside menstrual cycles, ovulation and fertility.
Poor metabolic health may affect both egg quality and the uterine lining. Insulin resistance, ongoing inflammation and reduced cellular energy can interfere with egg maturation and the hormonal signals that prepare the lining for pregnancy, potentially making it less receptive to an embryo.
Acupuncture and PMOS: what does the research suggest?
Acupuncture is one of the tools I use within an individualised care plan for women with PMOS, including those seeking support with their menstrual cycle and fertility goals.
Acupuncture may help women with PMOS ovulate and support their reproductive health. In a 2025 clinical trial, women who received acupuncture alongside letrozole had a higher pregnancy rate than those who received letrozole with sham acupuncture. My approach involves regular treatments over time, rather than just one or two appointments.
The researchers reported:
Higher ovulation rates across treatment cycles: 77.97% versus 49.74%.
Higher pregnancy rates across treatment cycles: 56.72% versus 29.85%.
Reduced testosterone levels: in the acupuncture group (P = 0.005).
Improved endometrial receptivity: the study’s Salle score–based response rate was 86.4% versus 67.2% (P = 0.005).
Lower blood-flow resistance measurements on ultrasound, measured using pulsatility and resistance indices (P < 0.001).
Both groups received letrozole. The treatment group also received acupuncture, while the comparison group received sham acupuncture. These findings are encouraging and suggest the positive effects of acupuncture on fertility in women with PMOS.
If you are trying to conceive, acupuncture can be considered as complementary care while continuing established fertility assessment and treatment.
For individualised PMOS support in Windsor, Melbourne or Ballarat, book a consultation with Dr Frances Tobeck, or call the clinic to find out more about how acupuncture might assist your health and fertility goals.
