Study of Acupuncture to Control Weight and Improve Pregnancy Rates in Overweight/Obese PCOS Patients

A Randomized Controlled Study of Acupuncture to Control Weight and Improve Pregnancy Rates in Overweight/Obese Polycystic Ovary Syndrome Patients

Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility and is characterized by ovulatory dysfunction, increased androgens, and polycystic ovaries. The goal of this randomized control study is to compare the efficacy between acupuncture and metformin both with intensive lifestyle intervention for overweight /obese PCOS patients in weight and pregnancy rates improvement.

A randomized control study is designed to compare the efficacy of acupuncture and metformin with intensive lifestyle intervention for overweight /obese PCOS patients in weight and pregnancy rate improvement. 92 patients will be enrolled from Renji Hospital affiliated with Shanghai Jiao Tong University School of Medicine and will be divided into 2 groups: acupuncture+ intensive lifestyle intervention group and metformin + intensive lifestyle intervention group. Each group used a specific treatment (shown as the group name) for 8 weeks. In this study, the role of acupuncture in improving weight control and pregnancy rate in overweight/obese PCOS patients will be evaluated, the safety and efficacy of acupuncture as well as metabolic measurements. Molecular targets and models for predicting the sensitivity and prognosis of acupuncture treatment, as well as in-depth research on the molecular mechanism of acupuncture in treating PCOS, have a guiding significance and promote the modernization of traditional medicine.

Inclusion Criteria:

1. Diagnosis of PCOS according to the 2003 Rotterdam criteria with at least two of the following three symptoms: clinical and/or biochemical signs of hyperandrogenism (hirsutism or acne), oligomerism/amenorrhea, and/or polycystic ovaries (PCOS). Biochemical hyperandrogenism is defined as total testosterone > 2.6 nmol/L or free androgen index >7. Hirsutism is defined as an FG score ≥7. Oligomenorrhea is defined as menstrual bleeding > 35 days between menstrual periods in the past year, < 8 menstrual bleeding. Amenorrhea is < 3 cycles per year. PCO is defined by transvaginal ultrasound, where one or both ovaries ≥ 12 follicles 2-9 mm and/or ovarian volume ≥ 10 mL. Other endocrine disorders such as atypical congenital adrenal hyperplasia (17-hydroxyprogesterone <3 nmol/L), androgen-secreting tumors, or suspected Cushing syndrome are excluded.
