Objective: To observe the regulative effect of electroacupuncture (EA) of Sanyinjiao (SP 6) on genito-endocrine in patients with perimenopausal syndrome (PMS).
Methods: A total of 175 PMS patients (157 cases with complete data) were randomized into EA group (n=81) and medication group (n=76) according to multi-center (3 hospitals) and single-blind control trial method. EA (2/100 Hz, 8-10 mA) was applied to bilateral Sanyinjiao (SP 6) for 30 min, 3 times every week, with one month being a therapeutic course, 3 courses altogether. Patients in medication group were ordered to take nilestriol (2 mg, twice/month for 3 months) and medrysone (2 mg, t. i. d. for 10 days from the 3rd month on). Serum estradiol (E) 2, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) were detected with a chemiluminescence immo-analysis system.
Results: After EA treatment, serum FSH and LH contents decreased significantly and serum E2 increased considerably (P < 0.001) compared with its basic values. Comparison between two groups showed that FSH, LH and E2 levels in EA group were significantly lower than those of medication group (P < 0.05).
Conclusion: EA of Sanyinjiao (SP 6) has a good regulative effect on reproductive endocrine function in PMS patients.
