Effect of Low-frequency Electroacupuncture (EA) on Polycystic Ovary Syndrome

Huazhong University of Science and Technology54 enrolled

Overview

Low-frequency electroacupuncture (EA) can decrease serum 17-hydroxyprogesterone (17-OHP), androstenedione (A) and testosterone (T)of young women with polycystic ovary syndrome in the Human chorionic gonadotrophin (HCG) stimulation test ，also，we hypothesize that EA is more efficiency in improving ovulation rate and menstrual cycle than sham acupuncture.

First, patients will be recruited according to the inclusion criteria and exclusion criteria. Second, baseline measurements (including menstrual frequency,human chorionic gonadotropin (HCG) stimulation test,physical examination,trans-abdomen ultrasound of the uterus and ovaries, serum levels of sex hormone steroids) will be taken. Third, each patient will receive 32 sessions of acupuncture in 16 weeks, twice a week. Last, the above baseline measurements will be taken again as soon as the treatment is finished and menstrual frequency will be recorded during the 12 weeks of follow-up after the treatment.

Interventions

acupuncture protocol 1OTHER

Disposable, single-use, sterilized needles made of stainless steel, 0.25 x 30 mm and 0.30 x 40/50mm (Wuxi Jiajian Medical Instrument. 251226 Wuxi, China) will be inserted to a depth of 15-35 mm in some acupoints. After getting the needle sensation (de qi), some acupoints will receive electrical stimulation and the others will receive manual stimulation. All participants will receive treatment twice a week; each treatment session can be separated by an interval of 2-4 days, with a maximum of 32 treatment sessions during 16 weeks. Each treatment session lasts for 30 minutes.

Acupuncture protocol 2OTHER

Disposable, single-use, sterilized needles (0.20 x 20mm) made of stainless steel will be inserted to a depth of \<5 mm at non-acupoints without evoking the needle sensation (Deqi). Electrodes will be attached to the needles and the stimulator will be turned on at an intensity of zero (no active current) in order to mimic EA in the acupuncture protocol 1 group. No manual stimulation of the needles will be performed.

Outcomes

Primary Outcomes

HCG stimulation test

Human chorionic gonadotrophin (HCG) stimulation test: Both at baseline and in one week after the treatment, the patients will receive an intramuscular injection of 5000 IU HCG, and 24 h and 48 h later, serum 17-hydroxyprogesterone (17-OHP), androstenedione (A) and testosterone (T) of the patients will be detected.

Time frame: 16 weeks

Secondary Outcomes

Laboratory examination

Serum levels of sex hormone steroids including blood follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen, progesterone, prolactin and total testosterone will be evaluated at baseline and 16 weeks. Oral glucose tolerance test (OGTT) and insulin releasing test will be performed at baseline and 16 weeks. Serum levels of leptin, adiponectin, resistin, adrenal cortical hormone and beta endorphin will be examined at baseline and 16 weeks later.

Time frame: 16 weeks

trans-abdomen ultrasound of the uterus and ovaries

The uterine dimensions, endometrial thickness and echo type, other uterine abnormalities, presence and size of leiomyoma, uterine artery blood flow parameters (pulsation index, resistance index, Shrinkage value / Diastolic value) will be obtained through trans-abdomen ultrasound at baseline and 16 weeks. The ovarian size in three dimensions, the size of the largest ovarian follicle/cyst and size of every follicle with a mean diameter greater than 10 mm, and total antral follicle (small follicles with mean diameter \< 10 mm) count of each ovary; ovarian artery blood flow parameters will be observed through trans-abdomen ultrasound at baseline and 16 weeks later.

Time frame: 16 weeks

Physical examination

Physical examination including vital signs, height, weight, hip and waist measurements, BMI and assessment of hirsutism by Ferriman-Gallwey score and acne standard acne lesion counts will be performed at baseline and 16 weeks.

Time frame: 16 weeks
