About this trial
The hypothesis is that acupuncture is equally effective as metformin (both treatments combined with lifestyle management) in improving whole body glucose homeostasis in insulin resistant women with polycystic ovary syndrome (PCOS), and that both are superior to lifestyle management alone. The investigators hypothesize that acupuncture and metformin induce ovulation and improve hyperandrogenism, as well as health related quality of life (HRQoL) and symptoms of anxiety and depression. Although equally effective (acupuncture and metformin), the investigators hypothesize that acupuncture is associated with less negative side-effects. The investigators also hypothesize that these treatments have the potential to restore epigenetic and molecular alterations in target tissues (endometrial-, adipose-, and skeletal muscle tissue) and thus have the potential to prevent the development of type 2 diabetes (T2D).
Eligibility criteria
Qualifiers

Body mass index (BMI) ≥25 to ≤40 given that 95% of all women with PCOS with a BMI ≥25 are insulin resistant (71,72).
PCOS diagnosis according to Rotterdam criteria 2003 (73), with at least two of the following three symptoms: Clinical signs of hyperandrogenism (hirsutism or acne); oligo/amenorrhea; and/or polycystic ovaries (PCOS). Hirsutism is defined as a self-reported Ferriman-Gallwey (FG) score ≥8 (≥5 Asian) (74,75). Acne is defined by a positive response to the question Do you have acne? Oligomenorrhea is defined as an intermenstrual interval >35 days and <8 menstrual bleedings in the past year. Amenorrhea as <3 cycles per year. PCO is defined by transvaginal ultrasound with ≥12 follicles 2-9 mm and/or ovarian volume ≥10 ml in one or both ovaries.
